The Federation Tower (Russian: Башня Федерация, romanized: Bashnya Federatsiya) is a complex of two skyscrapers built on the 13th lot of the Moscow International Business Center in Moscow, Russia. The two skyscrapers are named Tower East or Vostok (Russian: Восток; literally means "East") and Tower West or Zapad (Russian: Запад; literally means "West").

Key Information

The supertall skyscraper Tower East (Vostok) is currently the second-tallest skyscraper in Europe and Russia after the Lakhta Center, the tallest building in Moscow, and the 55th-tallest building in the world. Zapad is a shorter skyscraper than Vostok and is the eleventh-tallest building in Russia, and the 22nd-tallest building in Europe. The complex stands on the 13th lot, which has an area of 439,154 square meters.

The project was conceived by German-Russian engineer Sergei Tchoban and German professor and engineer Peter Schweger. The complex was designed by architecture companies nps+partner and Schweger Associated Architects. The complex started construction in 2005, with Zapad completed first in 2008 with a height of 242 meters (794 feet). As a result of the Great Recession, construction of the complex stopped until August 2011, and Vostok was completed on 7 December 2017 with a height of 374 meters (1,227 feet). In late 2014, Vostok surpassed the South Tower of OKO, which it is also part of the MIBC, as the tallest skyscraper of Russia and Europe. A spire was to be also built which would have extended the complex's height to 450 meters (1,480 feet) as well as provided an observation deck but it was never completed and was dismantled afterward.

The complex is owned by the AEON Corporation, a Russian private international investment group. The complex consists of two towers built on one podium. Tower East is a 97-story structure and Tower West is a 63-story structure. The complex is bounded by a rectangle of 3 alleys & a driveway. All three alleyways are named Krasnopresnenskaya Embankment, but the driveway on its east side is named 3rd Main Street. On 30 July 2023, across the alley from the back entrance, on the first floor, an aircraft (a Ukrainian drone) crashed into Rosbank (whose address is 1st Krasnogvardeisky Direction 19) & exploded, causing a small amount of damage to its facade.[2][3]

Tower East

[edit]

Planning and early development

[edit]

The higher tower of the complex located in the eastern part of lot number 13 was formerly known as Tower "A". But in November 2006, to avoid name competition with Naberezhnaya Tower, it was renamed Tower "Vostok (East)". Tower East is designed to have 95 above-ground and 3 underground floors, and 17 high-speed elevators will be installed there (JP. Kocher). According to the company Potok, which is the builder of the tower, it used grade B90 concrete which is twice as strong as regular concrete and will allow the skyscraper to withstand a direct hit of an aircraft. In early December 2009, the Potok Corporation management (ex-Mirax Group) announced that in the case of financial problems it could reduce the number of floors of Tower East from 95 to 64 floors. However, in March 2010, the company's management stated that Tower East would be completed according to the original project design.

The construction of this tower is the second stage of the entire complex construction, and during the construction of the first tower, "Zapad (West)", its design underwent some significant changes and became radically different from the original version. In the first place, the square footage of the floors changed, and visually the tower became thicker at the base to the extent that a part of the floors, starting with the 11th, protrude a little beyond the 13th lot borderline. The tower core was significantly revised, too, and now has a trapezoidal shape rather than hexagonal as in the earlier design. The load-bearing columns became twice as thick; therefore, the amount of concrete required for the construction of the columns increased 4 times, and, consequently, significantly increased the total mass of the building.

Construction

[edit]

Construction started in 2005. During the construction of the foundation slab on 21–24 February 2007, a new record listed in the Guinness Book of Records was set: 14,000 cubic meters of concrete were placed then. Somewhat unusual in the construction process was that the first base plate was covered with the second base plate, which resulted in the complex losing one underground level and the construction delayed by at least five months. The extravagance of this decision lies in the fact that, judging by the photographs obtained from the site, the builders began active preparations for the construction of the first underground floor, but suddenly stopped working, dismantled the installed cranes, cut the reinforcement bars previously prepared for the columns and began to place reinforcement for the second base plate. That the construction organizers did not clearly comment on the reasons for this decision was also unusual. The tower was climbed solo by the Frenchman Alain Robert in September 2007.

In the process of further construction the pace of the tower erection changed over a fairly wide range: the underground and podium parts of the building were being built at an average rate of about two levels a month; after the podium was completed, the construction of standard floors went at a faster rate of four floors per month, while at the technical 33–34 levels of the building the construction of that floor was significantly suspended and lasted more than five months; one of the cranes was replaced with two more powerful ones, and a strong metal outrigger structure was formed, contributing to the greater rigidity of the building and its resistance to wind loads.

As of mid-May 2008, the tower was built to a height of about 170 meters (560 feet). In November 2008, due to the Great Recession and a lack of funding, construction of the skyscraper was suspended.

The building is actively used as a sightseeing object and a high-rise structure for extreme sports lovers (base jumpers, climbers, etc.), as well as a site for shooting films and videos (TV shows, advertising, and movie production). In 2012, the Moscow 24 TV channel shot a movie about the business complex. Another film dedicated to the skyscraper was made by the Discovery Channel TV channel in 2009.

On 5 July 2011, the construction company Potok announced the tower construction to be resumed. The actual growth of the tower was scheduled to begin in September 2011. As of 30 March 2012, the 67th story of Tower East had been completed; the glazing of the tower was being conducted as well.

On 2 April 2012, firefighters and firefighting helicopters struggled to put out a massive blaze that broke out on the 67th floor of the under-construction Federation Tower East. "The fire was visible from much of the Russian capital's western half. Two firefighting helicopters noisily circled the blaze, dumping huge buckets of water on the flames before the Emergencies Ministry said the fire had been stopped from spreading by about 11:30 p.m. (1930 GMT), some three hours after it broke out."[4] "The area affected by the fire has exceeded 300 square meters (3,200 square feet)", Major-General Sergei Anikeyev, deputy head of the city's emergency department, told the news agency Itar-Tass. "The 14 people who were at the top floors when the fire started have been evacuated. No one was hurt," he told Itar-Tass.[5]

On 18 December 2014, Vostok was topped out when the skyscraper reached its planned height of 374 meters (1,227 feet). The construction teams, including Turner, celebrated the pouring of the last structural concrete cube, 374 meters above the ground. The topping-out generated excitement in the Russian press, as the tower received the title of being the tallest building in Russia and Europe, surpassing OKO's South Tower.[6]

On 20 January 2017, Europe's tallest elevator shaft was constructed in Vostok, with the launch of the tallest elevator in Europe taking place simultaneously with the opening of the southern entrance lobby of the tower. According to Russian Construction, the elevator's cabin moves without switches from the second underground level to the 94th story. Schindler freight-passenger elevator will go up at the height of 355 meters above the ground level. Its total path of motion with the consideration of underground floors will amount to 365 meters. The elevator's carrying capacity is 2 tons.[7] During an interview with the director general of the "Federation Tower" Ltd., Mikhail Smirnov by Iterfax-Realty, construction of the skyscraper would finish by the end of March 2017. Earlier, the Moscow State Construction Supervision Committee reported that the tower would be put in operation by July 2017, Interfax reports.[8]

On 6 October 2017, the Lakhta Center of St. Petersburg surpassed Vostok's height of 1,227 ft (374 m), making it the tallest building in Russia and Europe.[9]

On 7 December 2017, construction of Vostok was completed, making it the tallest completed skyscraper in Russia and Europe currently.[10]

Purpose

[edit]

Vostok would be used for multiple purposes, high rise development designed to house offices, retail areas, a five star hotel, and luxury apartments upon completion. A number of luxurious offices will occupy the penthouse's area of 12,000 square meters from the 90th to 98th stories.[11] The upper levels of the 95-story tower will include the hotel lobby, restaurants, and a public viewing platform. The lower levels will contain retail shops and restaurants as well as the hotel's ballroom, and conference and events center.[6] The building would also feature the highest digital clock in the world.

Tower West

[edit]

Planning and early development

[edit]

The lower tower of the complex is located on the western part of lot 13 in the MIBC. The tower was formerly known as Tower "B" but in order to avoid name competition with Naberezhnaya Tower, it was renamed Tower "Zapad (West)". In November 2006, after the name competition, it was renamed Tower West. Tower West is planned to have 62 stories above ground and four underground floors, with 11 twin and six high-speed elevators.

Construction

[edit]

The erection of Tower West was the first stage of the entire Federation complex construction, but the height of the tower was increased in comparison with the original models (originally, Tower West was planned to be half the height of Tower East). The cross-section of the tower's core, originally planned to be hexagonal, was modified after construction began and is now trapezoidal. The core was constructed so it rose above the rest of the structure, which was assembled one or two floors behind. The building was completed in early 2008.

Purpose

[edit]

Tower West would include a hotel spa and swimming pool. The 61st floor of the Tower West accommodates the tallest restaurant in Moscow, 'Sixty', run by Ginza Project.[citation needed]

Awards

[edit]
  • 2009 – The western tower of the Federation business complex was the winner of the World FIABCI competition Prix d'Excellence in the category "Office Property".[citation needed]
  • 2011 – The Federation Tower was awarded with the "Records of real estate market" prize in the "Business Center No 1" nomination.[citation needed]

View on Grokipedia
from Grokipedia
The Federation Tower is a supertall skyscraper complex situated in the Moscow International Business Center (Moscow City) in Moscow, Russia, comprising the East Tower (Vostok) and West Tower (Zapad), with the former standing at an architectural height of 373.7 meters (1,226 feet) across 93 floors above ground and the latter at 239 meters (784 feet) with 63 floors. Developed initially by Mirax Group and designed by architects including Sergey Tchoban and Peter Schweger, the complex serves mixed uses including offices, residential apartments, and a hotel, marking a key element of Moscow's post-Soviet architectural transformation into a global business hub. The East Tower, completed in 2016 after construction began in 2005, briefly held the record as Europe's tallest building upon reaching its height milestone in 2014, utilizing pioneering super high-strength concrete technology for the first time in Russia, though it was later eclipsed by Saint Petersburg's Lakhta Center in 2018. Construction faced significant setbacks, including a major fire in 2012 that engulfed upper floors of the East Tower, highlighting safety and regulatory challenges in Russia's rapid skyscraper development. Despite such incidents and developer financial difficulties leading to ownership changes, the complex stands as an engineering achievement, contributing to Moscow's skyline with over 3.5 million square feet of floor area and earning international architecture awards for its design.

Overview

Location and Site Context

The Federation Tower complex is situated at Presnenskaya Embankment, 12, in the Presnensky District of central , , as part of the (Moscow-City). It occupies plot number 13 within this planned development zone, encompassing 10,730 square meters of land. Moscow-City lies on the Presnensky Peninsula bordering the Moskva River, an area designated for redevelopment in 1992 to create Russia's primary financial district on previously underutilized territory west of the city center. This site was selected due to its strategic central position and the unique scale possible for high-density business construction, distinguishing it from other Moscow locales constrained by historical or infrastructural limitations. The immediate site context integrates the towers into a cluster of supertall skyscrapers, including the adjacent and Eurasia Tower, fostering a vertical with integrated commercial, residential, and facilities. The surrounding Presnensky area benefits from proximity to major transport links like the Third Ring Road and Kutuzovsky Avenue, supporting its function as Moscow's economic nerve center amid a backdrop of evolving post-Soviet .

Architectural and Engineering Significance

The Federation Tower complex exemplifies pioneering architectural ambition in post-Soviet , introducing the concept of a "vertical " for the first time in the country's modern history, with integrated mixed-use spaces spanning offices, residences, and amenities across its towers and podium. Designed primarily by Sergey Tchoban of SPEECH and Peter Schweger of Schweger Architekten, the towers feature a unified aesthetic code emphasizing dynamic facades that vary by orientation while maintaining structural coherence, drawing on contextual urban integration within Moscow's Center. At 374 meters for the Vostok (East) Tower, it held the title of Europe's tallest building upon completion in 2016, symbolizing a leap in supertall design that prioritized visual lightness through slender profiles and glazed envelopes despite extreme height. Engineering significance lies in its adaptation of advanced structural systems to Moscow's environmental demands, including high loads and subzero temperatures, marking the first Russian application of super high-strength for supertall construction. The core-and-outrigger system comprises a robust central —1.4 meters thick at the base—reinforced by 25 perimeter columns (each 2 x 1.4 meters at foundation) and three levels of steel outrigger trusses every 25-30 stories to efficiently transfer gravity and lateral forces, enabling the towers' tapered forms without excessive material use. Foundations rest on a massive for load distribution, while innovations like twin systems—allowing dual high-speed cars per shaft—enhance vertical mobility efficiency, a domestic first. The facade employs Russia's inaugural structural glazing with argon-filled insulating units, optimizing and transparency. These elements collectively demonstrate causal advancements in load-path optimization and material resilience, setting precedents for subsequent high-rises in seismic-inactive but climatically harsh regions.

Planning and Design

Initial Conception and Site Selection

The Moscow International Business Center (MIBC), within which the Federation Tower is situated, originated from a 1991 proposal by Soviet architect Boris Tkhor to develop a dedicated business district in Moscow, addressing the post-Soviet need for modern commercial infrastructure amid economic liberalization. The site's selection in the Presnensky District, spanning roughly 100 hectares along the Presnenskaya Embankment east of the Third Ring Road, prioritized underutilized industrial and riverside land approximately 4 kilometers west of the Kremlin, enabling high-density vertical construction without encroaching on central historical zones while leveraging proximity to transportation and the Moskva River for logistical advantages. This location facilitated the subdivision into multiple plots for phased skyscraper development, transforming a former quarry and low-rise area into a self-contained financial hub. The Federation Tower's specific plot, designated as one of MIBC's key parcels, was initially earmarked for the —a 600-meter supertall designed by Norman Foster and Boris Thor—but the project was shelved due to economic and technical hurdles, prompting a pivot to the Federation concept to maintain momentum in supertall ambitions. Developer Sergei Polonsky's Mirax Group acquired to the site in the early , viewing it as ideal for pioneering Russia's entry into global competition given its stable soil post-remediation and alignment with MIBC's master plan for clustered high-rises. Conceived by German-Russian architect Sergei Tchoban and engineer Peter Schweger, the Federation Tower was envisioned as a "vertical "—integrating offices, apartments, hotels, and public amenities in a single complex—to symbolize Russia's architectural ascent and economic vitality, with construction groundwork initiating in 2003 to claim Europe's height supremacy. This approach drew on the site's expansive footprint and allowances, prioritizing multifunctional over horizontal sprawl to optimize in Moscow's constrained urban fabric.

Design Process and Architects

The Federation Tower complex was conceived in 2003 by Russian-German architect Sergei Tchoban, through his firm NPS Tchoban Voss Architekten, in collaboration with German architect Peter Schweger of Schweger Architekten, as a flagship supertall development for the Moscow International Business Center. The initial design positioned the towers as the visual and functional dominants of the site, with a shared stylobate plinth integrating office, residential, hotel, and retail spaces into a "vertical city" model—the first such implementation in modern Russian architecture. This concept drew on high-rise precedents emphasizing mixed-use efficiency and iconic silhouettes, featuring paired glass "sails" for the towers to create a dynamic, sail-like profile symbolizing forward momentum. The design process involved iterative collaboration among international firms, incorporating Tchoban Voss Architekten for conceptual and facade development, Schweger Architekten for structural integration, and the Russian firm SPEECH for detailed execution, particularly on the East Tower (Vostok). Engineering input from firms like focused on adapting the design to site-specific challenges, such as seismic activity and wind loads, while pioneering super high-strength usage in to achieve the East Tower's 97 stories and 374-meter height including . Tchoban's biodesign influences, evident in organic facade geometries, complemented Schweger's engineering precision, ensuring the towers' 442,915 m² gross area balanced aesthetics with constructability. Despite financial delays halting progress after 2008, the core architectural vision remained intact upon resumption, with final approvals reflecting the original parameters adjusted for updated building codes and material advancements. The collaborative model exemplified cross-border expertise, prioritizing empirical structural performance over stylistic novelty, as validated by post-completion awards including the Chicago Athenaeum International .

Intended Purpose and Economic Rationale

The Federation Tower complex was developed as a multifunctional "vertical city" within the (MIBC), marking the first implementation of this concept in post-Soviet . It integrates premium Class A spaces across lower floors, luxury residential apartments in upper levels, a high-end , retail galleries, restaurants, and leisure amenities such as a wellness club and panoramic , all connected via a shared and underground infrastructure. This design facilitated a self-contained environment for professional, residential, and commercial activities, optimizing vertical space on the 100-hectare development site near the Krasnopresnenskaya embankment. Economically, the tower served as a strategic anchor for positioning as a competitive global financial hub, drawing on an exceeding $740 million to construct advanced facilities including energy-efficient glazing, cutting-edge , and integrated links like a dedicated mini-metro. The rationale emphasized attracting and multinational firms through modern totaling millions of square feet, alongside residential and components to support a of elites. As part of the broader $10-12 billion MIBC initiative, it aimed to catalyze economic diversification beyond resource extraction, generate high-skilled employment, and project Russia's modernization ambitions internationally by establishing a prestigious dominant in Europe's tallest building at completion.

Construction

Timeline and Key Milestones

Construction of the Federation Tower complex's (Zapad) began in 2005 and reached completion in , standing at 242 meters with 63 floors. The East Tower (Vostok), intended as the taller structure at 374 meters with 97 floors, saw initial groundwork in the mid-2000s but faced significant delays following the global financial crisis, which halted progress amid developer Mirax Group's bankruptcy proceedings. Work resumed in August 2011 under new ownership by AEON Corporation, focusing on resuming and accelerating the East Tower's development. Key structural milestones for the East Tower included reaching advanced height stages by 2015–2016, with the spire installation marking around that period, enabling it to claim Europe's tallest building status temporarily. Full architectural completion of the complex occurred on November 15, 2017, followed by official handover of the East Tower on December 7, 2017, incorporating office, residential, and functions. These dates reflect verified engineering and occupancy certifications, prioritizing empirical project logs over earlier projected timelines affected by economic disruptions.

East Tower Development

Construction of the East Tower, known as Vostok Tower, commenced in 2004 alongside the broader Federation Tower complex in Moscow's International Business Center. Initially designated as Tower A, it was renamed Vostok in November 2006 to reflect its eastern position on the site. Progress advanced rapidly in the early stages, with the underground and sections built at approximately two floors per month, accelerating to four floors per month up to levels 33-34, and reaching 45 floors by May 2008. The global financial crisis prompted a suspension of work from 2008 to 2011, leaving the East Tower as the world's tallest building on hold during that period. In 2009, developers considered reducing its height to 69 floors amid funding shortages, but this plan was abandoned by March 2010 in favor of the original design. Resumption occurred in 2011 under new ownership by AEON Corporation, though further delays persisted until late 2013, with substantive advancement restarting in spring 2014. A significant setback occurred on April 2, 2012, when a erupted on the 65th floor amid stored materials, raging for several hours but resulting in no injuries or major structural damage. Following resumption, the monolithic frame reached completion on December 9, 2014, marking a key milestone that temporarily positioned the tower as 's tallest structure at 343 meters by November 25, 2014. Originally envisioned with a height exceeding 500 meters including an ambitious spire, the design was scaled back to 374 meters due to aviation regulations and project revisions, with the separate 506-meter spire element ultimately dismantled in 2015 after partial construction. The tower achieved full operational completion on November 15, 2017, comprising 93 floors dedicated primarily to office space.

West Tower Development

The West Tower, known as Zapad Tower, marked the initial construction phase of the Federation Towers complex on Lot 13 of the . Construction began in 2005, focusing on erecting the 63-story structure to a height of 243 meters atop a shared nine-story with the adjacent East Tower. This phase prioritized rapid vertical progression using core and perimeter columns for stability in seismic conditions. Progress advanced without the prolonged interruptions that affected the taller East Tower, enabling topological completion by 2008. The tower's design incorporated glass facades and a crystalline form, aligning with the complex's aesthetic while accommodating office functions from lower levels upward. Upon finishing, Zapad stood as a functional high-rise at 242 meters, serving as an operational anchor for the site amid broader economic pressures from the that stalled adjacent work. Engineering efforts emphasized wind resistance and foundation integrity on soft Moscow soils, with pile foundations driven to depths exceeding 50 meters. No major incidents like the fires that plagued later phases of the complex were recorded for Zapad's build, contributing to its timely handover for tenant fit-outs. By 2009, the tower was partially occupied, underscoring its role in kickstarting commercial activity in .

Engineering Challenges and Solutions

The Federation Towers' construction demanded innovative structural solutions to achieve heights exceeding 300 meters on Moscow's geotechnically challenging site, characterized by compressible alluvial soils requiring deep pile foundations to mitigate settlement risks. Engineers employed a composite foundation system with bored piles extending up to 60 meters into bedrock, combined with a reinforced concrete raft slab, to distribute loads and ensure long-term stability amid the site's proximity to the Moskva River. A primary challenge was sourcing and applying ultra-high-strength , with compressive strengths over 80 MPa, which was scarce in at the project's outset due to limited local manufacturing expertise and supply chains geared toward standard grades. This was addressed through collaboration with international specialists, marking the towers as the first in to incorporate super high-strength technology, allowing for more efficient column and core designs while enhancing durability against environmental stresses like freeze-thaw cycles. Lateral load resistance, driven by high wind pressures at elevation, necessitated a robust core-and-outpost system: a central core with walls thickening to 1.4 meters at the base for shear and torsional , augmented by 25 perimeter columns spanning the full to form a perimeter frame that minimizes sway and vortex-induced oscillations from the towers' helical . Integration of up to 30 interdependent engineering systems—encompassing HVAC, electrical, and —posed coordination difficulties in a vertically elongated structure with constrained shaft spaces, resolved via advanced BIM modeling for clash detection and optimized routing, alongside zoned pressurization to maintain fire compartmentation and smoke control. The facade engineering addressed thermal bridging and energy loss in Moscow's sub-zero winters through Russia's inaugural use of structural glazing with argon-filled insulating glass units, providing a curtain wall system that seals against air infiltration while supporting wind loads without intermediate mullions, thus preserving the aesthetic taper.

Architectural Features and Technical Specifications

Structural Design and Materials

The Federation Tower complex employs a composite structural system featuring a for primary lateral stability, supplemented by trusses that connect the core to perimeter columns, enabling efficient load distribution under wind and seismic forces. Three levels of these truss systems are incorporated, with the deepest at approximately 20 feet (6 meters) on the 33rd floor, optimizing stiffness while accommodating architectural constraints. Foundations consist of a massive supporting both towers on a shared , with base columns measuring 2 meters by 1.4 meters to handle gravitational loads from the . The East Tower (Vostok), reaching 374 meters, pioneered the use of super high-strength in , achieving compressive strengths exceeding standard limits to support its height and slenderness. High-strength structures form floors every 25-30 levels, enhancing overall rigidity without excessive material use. Construction materials emphasize locally sourced reinforced concrete for cores and slabs, combined with steel for trusses and perimeter framing to balance cost, availability, and performance in Moscow's variable soil and climatic conditions. The system's design, engineered by , integrates these elements to resist overturning moments, with perimeter steel elements and concrete floor systems providing redundancy.

Height, Floors, and Spire Details

The Federation Tower complex consists of two primary towers: the East Tower (Vostok), which stands at an architectural height of 373.7 meters including its spire, and the West Tower (Zapad), measuring 242.5 meters without a spire. The East Tower features 93 floors above ground and 4 below ground, with the uppermost levels dedicated to observation, residential, and hospitality functions up to an occupied height of 360.1 meters. The West Tower has 63 floors above ground, primarily serving office purposes.

The East Tower's spire forms part of its architectural top, contributing to its status as Russia's tallest completed building upon in 2016, though initial designs envisioned a taller, shared structure between the towers reaching 506 meters for enhanced observation capabilities, which was ultimately not realized due to and regulatory revisions. Floor counts adhere to standards excluding minor mezzanines or non-habitable levels, ensuring consistency in tall building metrics.

Sustainability and Technological Innovations

The Federation Tower complex incorporates several technological innovations in its vertical transportation systems, including the first installation in of twin configurations, where two independent high-speed cars operate within a single shaft—one reaching speeds of 6 m/s and the other 8 m/s—to minimize wait times and enhance capacity. Additionally, the features unique glass-walled inclined operating at a 10-degree , providing panoramic views during transit. Structurally, the towers employ floors at intervals of 25 to 30 stories, reinforced with high-strength trusses connecting a central core—measuring 1.4 thick at the base—to 25 perimeter columns (each 2 by 1.4 at the base), ensuring lateral stability against and seismic forces. The complex marks Russia's inaugural use of super high-strength , particularly in the East Tower (Vostok), enabling the structure to reach 374 in height while optimizing material efficiency. In terms of energy efficiency, the towers feature Russia's first structural glazing facade system utilizing argon-filled insulating glass units, which reduce heat transfer and enhance thermal performance. The complex connects to a centralized modern boiler house providing cooling, heating, and a high-efficiency heat-recovery system, with staggered climate control tailored to diverse occupancy zones (office, residential, and retail) to optimize resource use. Construction emphasized local sourcing of steel and reinforced concrete, supplemented by river transport via the Moskva River to minimize road traffic emissions. These elements contribute to overall operational efficiency within the Moscow International Business Center's integrated infrastructure, though the complex lacks formal international green building certifications such as LEED.

Tenants and Operational Use

Commercial and Office Occupants

The Federation Tower complex primarily houses Class A spaces in its East and West towers, with tenants concentrated in , , trading, and professional agencies. The lower floors of Tower East feature accommodations across approximately 57 levels, while Tower West includes areas alongside hospitality elements. Demand for space remains high, contributing to low vacancy rates in the , where the overall Class A vacancy fell to 1.9% in the first quarter of 2025. Key commercial occupants include investment and trading firms such as West Capital Group, which maintains operations in the tower for daily business activities from 10:00 to 20:00. Forex4you, a dealing center, and ForexInn, a brokerage firm, are among the providers leasing space, reflecting the tower's appeal to entities in and derivatives trading. Advertising and media agencies, including Buzzcraft and Immobiliare Zinovieva, also occupy offices, leveraging the prestigious location for client-facing operations. Engineering and consulting firms represent another segment, with Blue Projects establishing its Moscow headquarters in the tower in February 2019 to support regional project management. Retail-oriented commercial spaces, such as Apl5 (an electronics retailer), occupy podium-level areas accessible to the building's residents and visitors. Higher "SKY-offices" above the 50th floor, offering panoramic views, attract premium lessees seeking enhanced prestige, with lease rates ranging from 65,000 rubles per square meter annually for open-space formats. The mix underscores the tower's role as a hub for mid-sized firms in niche financial and service sectors rather than dominant multinational anchors.

Residential and Hospitality Elements

The Federation Tower complex incorporates luxury residential apartments primarily in the upper levels of the Vostok (East) Tower, commencing from the 69th floor at an elevation of approximately 250 meters, designed exclusively for high-end living with unobstructed panoramic views of and beyond. These units, intended for affluent buyers, feature customizable unfinished interiors, ceiling heights ranging from 3.2 to 5.5 meters, and expansive 1.8-meter-wide glass panels across floors 84 to 97, with areas spanning 54.1 to 719 square meters. Apartments in the complex, including two- and three-room configurations with private loggias, cater to premium occupancy, as evidenced by active sales and rentals such as a 110-square-meter one-bedroom unit on a mid-level floor listed at $710,000 and a 172-square-meter designer-finished space on the 53rd floor. A standout residential feature is the three-story penthouse crowning the Vostok Tower under a large glass dome, billed as Europe's highest apartment at 23,476 square feet, equipped with 10 bedrooms, 10 bathrooms, lounge areas, a bar, multiple dining spaces, a , music room, wine cellar, , cigar lounge, and access to building-wide amenities including a . Hospitality elements within the complex emphasize resident-focused services rather than a standalone , including a wellness club, panoramic restaurant, and Europe's highest on the 61st floor, enhancing the vertical living experience with recreational and dining facilities integrated into the tower's design. Although early project plans outlined a five-star component, operational emphasis has shifted to these shared amenities supporting residential use, with no current evidence of dedicated hotel occupancy in verified sources.

Amenities and Public Access

The Federation Tower complex provides limited public access, primarily through its base-level retail galleries and upper-floor observation facilities, while most amenities such as fitness centers and pools are reserved for tenants, residents, and hotel guests. The and underground levels feature approximately 15,000 square meters of shopping space with branded stores, cafes, and escalator connections from the main atrium, facilitating pedestrian flow integrated with the broader . A key public attraction is the PANORAMA360 on the 89th floor of the East Tower (Vostok), Europe's highest at approximately 374 meters, offering 360-degree panoramic views of , interactive entertainment zones, an animation program, unlimited and chocolate fountains, a cinema, and a .

Internal amenities like a 1,200-square-meter gym with zones, group fitness rooms, swimming pools, and services on lower levels primarily serve office workers, apartment residents, and the five-star , rather than unrestricted use, though some retail-adjacent cafes extend casual access.

Controversies and Criticisms

Construction Delays and Financial Hurdles

Construction of the Federation Towers, initiated by Mirax Group in 2007, encountered severe setbacks in November 2008 when work halted due to the global financial crisis and acute funding shortages. The developer, facing insurmountable debts exacerbated by the recession, suspended operations on the East Tower (Vostok) after reaching approximately 30 floors, leaving the project dormant for nearly three years. This pause stemmed from Mirax's inability to secure credit amid Russia's property market collapse, where high interest rates and investor withdrawal crippled ongoing developments. Mirax Group's financial distress intensified as creditors, including , pursued legal action, resulting in a Moscow court freezing the company's assets in 2009 over unpaid debts totaling at least $242 million. Founder Sergei Polonsky's firm, rebranded as Potok in late 2011, inherited substantial liabilities estimated at $550 million, encompassing obligations to state bank and bondholders. Despite these hurdles, Potok announced resumption of construction on July 5, 2011, with vertical growth restarting in September, supported by creditor financing led by , which committed to overseeing completion. The delays cascaded into prolonged timelines, with the West Tower (Zapad) partially advancing but the taller East Tower lagging significantly; initial projections for 2012 completion slipped repeatedly, culminating in Vostok's in 2016 and full operational readiness in 2017. Financial strains persisted post-resumption, as Potok navigated ongoing creditor pressures and Polonsky's personal legal battles, including convictions in 2017 that further clouded the project's stability. These issues highlighted broader vulnerabilities in Moscow's boom, where overambitious developments outpaced economic resilience, leading to investor caution and elevated vacancy risks in the .

Safety Violations and Incidents

On April 2, 2012, a major broke out on the upper floors of the under-construction Federation Tower East, starting around the 65th floor among construction materials and , and rapidly spreading due to strong winds and the absence of a , as the building was not yet commissioned. The blaze, visible across much of , engulfed approximately 2,000 square meters and reached heights of up to 250 meters, requiring over 100 firefighters and helicopters to extinguish it after about four hours, with no injuries reported among workers who evacuated promptly. This incident underscored vulnerabilities in high-rise safety protocols at the , where rapid development often prioritized speed over interim fire protections, though preliminary investigations did not publicly attribute it to specific code violations beyond the inherent risks of unfinished structures. No other significant safety incidents, such as worker fatalities or structural failures, have been documented during the tower's or operation. In response to broader high-rise risks observed in projects, including Federation Tower, a specialized fall protection system was implemented starting in June 2006 to mitigate hazards from heights exceeding 100 meters, featuring perimeter netting and anchor points integrated into the facade during crane operations. Post-fire reviews did not result in formal penalties against the developers, but the event contributed to heightened scrutiny of compliance in Russia's skyscraper boom, where incomplete buildings lack operational sprinklers or hydrants. The Federation Tower complex, particularly its East Tower (Vostok), has been associated with multiple and over-the-counter (OTC) firms implicated in of ransomware proceeds and other illicit funds. Cybersecurity analyses indicate that firms operating from the tower, such as Suex OTC, processed at least $160 million in from high-risk and illicit sources between 2019 and 2021, including funds tied to attacks on U.S. entities. These operations facilitated the conversion of digital assets into fiat currency, enabling criminals to cash out payments from victims including American hospitals, companies, and governments. U.S. authorities sanctioned Suex in 2021 for laundering activities, with firm reporting that 26% of funds received by the exchange originated from illicit addresses. Additional tenants, including EggChange on the 22nd floor, faced investigations in the U.S. and for similar allegations tied to . Reports estimate that over $100 million in ransomware-related transactions flowed through City entities, with Federation Tower serving as a hub due to its prestige and lax oversight in Russia's financial district. More recent disclosures link tenants like Smart and TGR Group, based in the tower, to a multi-billion-dollar network laundering proceeds from ransomware, narcotics trafficking, and sanctions evasion. The U.S. Treasury designated TGR Group in December 2024 as part of an extensive operation obfuscating illicit client activities, including those evading Western sanctions post-2022 Ukraine invasion. These firms provided layering services for digital assets, integrating dirty money into the Russian financial system while connections to sanctioned exchanges like Garantex amplified evasion risks. Despite Russian regulatory efforts, such as closing some exchanges by 2025, the tower's role highlights systemic vulnerabilities in Moscow's crypto ecosystem.

Awards and Recognition

Design and Construction Accolades

The Federation Tower complex earned the International Architecture Award in 2019 from The Chicago Athenaeum, recognizing its pioneering vertical city concept realized through a design featuring two mirrored towers with sloping glass facades that narrow upward, marking the first such implementation in modern Russian architecture. The award highlighted the structure's memorable silhouette, formed by glass sails facing the River, and its integration of multifunctional spaces including offices, residences, and amenities within a 374-meter height for the Vostok Tower. In the construction domain, the project was the first in to employ super high-strength concrete technology, enabling the Vostok Tower to reach 373 meters and secure recognition from the Council on Tall Buildings and Urban Habitat (CTBUH) as Europe's tallest building upon its 2017 certification, surpassing previous records with structural innovations that ensured seismic and wind resistance. Architect Sergei Tchoban, co-designer with Peter Schweger, received the 2018 European Prize for Architecture, which cited the tower's role in elevating Moscow's skyline through advanced engineering that balanced aesthetic form with functional vertical urbanism. The complex also secured the Grand Prix at the International Property Awards 2019-2020 for its overall design excellence, including panoramic glazing and multifunctional layout, as evaluated by an international jury assessing architectural merit and innovation. Additionally, it won in the European Property Awards for best international , underscoring its construction achievements in integrating high-rise , residential, and retail elements without compromising structural integrity. Earlier, in 2009, the Zapad Tower component received the Prix d'Excellence from FIABCI in the category, affirming its early design viability amid the broader Moscow City development.

Impact on Urban Development

The Federation Tower complex has profoundly influenced Moscow's urban fabric as a flagship project within the (MIBC), accelerating the shift from Soviet-era low-rise dominance to a skyline dominated by supertall structures. Tower East, reaching 374 meters upon its 2016 completion, established a new height benchmark for the city and at the time, embodying vertical expansion strategies that address land scarcity in the capital. This architectural milestone not only redefined Presnensky District's silhouette but also catalyzed subsequent high-rise developments, fostering a cohesive business district that integrates commercial, residential, and leisure functions. Economically, the towers have anchored MIBC's role as a financial hub, providing approximately 443,000 square meters of premium and mixed-use space that attracts multinational corporations and high-net-worth individuals, thereby elevating values and stimulating local exceeding $12 billion across the district. The $1.2 billion cost underscores its scale, contributing to job creation in , , and services while enhancing Moscow's global competitiveness as a destination. By concentrating Class A , it has diversified the beyond traditional sectors, supporting Russia's GDP contributions from the capital, which account for about 25% nationally. In terms of , the Federation Tower pioneered the "vertical city" concept in post-Soviet , stacking offices, apartments, hotels, and amenities—including Europe's highest —within interconnected structures to promote efficient density and reduced . This model has influenced MIBC's overall layout, incorporating advanced infrastructure like enhanced transport links and energy-efficient designs that achieve up to 50% lower consumption than legacy buildings. Such innovations have improved public accessibility and , transforming a former industrial zone into a vibrant, pedestrian-oriented enclave that boosts and daily foot traffic.

Recent Developments

Final Completion and Occupation

The Vostok Tower, the taller component of the Federation Tower complex, achieved structural completion on December 7, 2017, reaching a height of 374 meters across 97 floors, surpassing previous European records for tallest buildings. This milestone followed resumption of construction in 2011 after delays from the , with the full complex—including the earlier-completed 242-meter Zapad Tower—deemed operationally ready by late 2017. The towers incorporate advanced engineering features, such as trusses for stability, enabling occupancy in upper levels previously reserved for construction access. Occupation has centered on Class A , with the complex hosting financial, legal, and corporate tenants drawn to its prestige and location. High-floor offices, such as a 77 m² unit on the 70th floor of the Vostok Tower, have been marketed for at premium rates exceeding 450,000 rubles monthly, reflecting demand for modern fit-outs and panoramic views. By early 2025, overall vacancy in City dropped to a record low of 1.9%, with Federation Tower contributing to this trend amid limited new supply and rising interest in premium assets. Limited residential elements, including a high-altitude penthouse under a glass dome marketed as Europe's highest , have emerged in upper levels, though commercial use dominates the occupancy profile. Sustained low vacancies signal robust post-completion utilization, supported by infrastructure upgrades like direct metro access and proximity to financial hubs.

Post-2023 Updates and Future Prospects

In 2024, retail vacancy rates in the , encompassing the Federation Tower, declined to a record low of 5.8% in the first half of the year, reflecting sustained demand for commercial space despite . Office vacancy in Class A buildings within the district, including those like the Federation Tower, reached a historic low of 1.9% in the first quarter of 2025, down from higher levels in prior years, driven by increased domestic leasing activity. By October 2025, Class A vacancy had further decreased to 1.2%, indicating robust occupancy and limited availability amid a shift toward local tenants resilient to external pressures. Current tenants in the Federation Tower include financial firms such as and West Capital Group, alongside service providers like Office 24/7 and wellness facilities such as Nebo club, underscoring its role as a hub for high-end business operations. Average rental rates for prestigious towers in City surpassed 80,000 rubles per square meter per year by August 2025, a historic high that signals strong market confidence and pricing power for premium assets like the Federation Tower. Looking ahead, the Federation Tower is positioned to benefit from Moscow City's planned expansion, with office space projected to increase by nearly 50% by 2030–2031 through new developments such as iCITY-2, One, Sezar Tower, and Empire II, enhancing the district's status as Russia's premier business enclave. This growth trajectory, coupled with ongoing low vacancy and domestic investment redirection amid sanctions, suggests sustained viability and potential for upgraded amenities or tenant diversification, though specific tower-level plans remain tied to broader district dynamics.
