The Mukaab (Arabic: المكعّب, romanizedmukaʻʻab, lit.'cube', [mukaʕʕab]) is a 400-meter (1,300 ft) tall cube-shaped skyscraper in the al-Qirawan district of Riyadh, Saudi Arabia, one of the five neighborhoods of the planned real estate development of New Murabba. Launched in February 2023, its cuboidal layout and design are inspired by the Murabba Palace.[1][2][3] Upon completion, the Mukaab will become the world’s largest building by volume.[4]

Key Information

Background

[edit]

The massive undertaking was announced by the Kingdom's ruler Crown Prince Mohammed bin Salman on February 16, 2023.[5][6] The design has been the subject of some criticism for its similarity to the Kaaba at the Masjid al-Haram mosque in Mecca, Islam's holiest shrine.[7]

The interior as currently planned will feature enormous holographic projections aimed at making viewers feel as if they are in different realities, times, and places. The interior will also feature a swirling tower for observation decks and restaurants, from which the projections will emanate.[8]

The Mukaab is planned to be the centerpiece of a giant new downtown built within the Saudi capital city of Riyadh called New Murabba. It will be the world's largest single-built structure with around 2 million square metres (22 million square feet) of interior floor space.[9][10][6][11]

The project will be undertaken by the New Murabba Development Company of which Crown Prince Mohammed bin Salman is the President.[12]

The cube is intended to be 400 meters (1,300 ft) tall and 400 meters (1,300 ft) wide on each of its four sides.[13]

Plans for the cube are part of the Saudi Vision 2030 project.[14]

The building's design is inspired by the modern Najdi architectural style.[15]

The Mukaab will also feature a rooftop garden.[16]

Broader New Murabba Context

Project Scope and Components

New Murabba constitutes a 19 km² mixed-use urban district in northwestern , , designed to function as the city's modern downtown and gateway for future development. The project, overseen by the New Murabba Development Company—a of the formed in 2023—encompasses over 25 million m² of total across residential, commercial, cultural, and recreational components. Key elements include more than 104,000 residential units, approximately 9,000 rooms, over 980,000 m² of retail space, and 1.4 million m² of , fostering a self-contained environment with amenities accessible within 15 minutes for residents. The district allocates 25% of its area to green spaces, incorporating walking and cycling paths to promote sustainable mobility and urban livability. Mixed-use zoning integrates cultural districts, entertainment venues, and advanced transport infrastructure, including connections, to create a dynamic hub blending residential living with commercial and leisure opportunities. This holistic scope positions as a foundational element in Riyadh's urban expansion, emphasizing technology-driven without reliance on traditional cores.

Urban Integration and Planning

New Murabba, incorporating the Mukaab as its central feature, occupies a 19-square-kilometer site in northwestern at the intersection of King Salman and King Khalid roads, enabling northward expansion while linking to the city's established road network and adjacent districts. This positioning supports directed urban growth by channeling development outward from the dense core, avoiding haphazard peripheral expansion through predefined boundaries and connectivity to existing utilities and transport corridors. Unlike critiques framing such initiatives as disconnected sprawl, the layout emphasizes contiguous integration, evidenced by coordinated that aligns with Riyadh's master plan for phased increases in underutilized northern zones. The development implements a framework, where residential, commercial, educational, and recreational facilities are configured so that 104,000 homes and lie within a 15-minute walk or ride for most residents, directly causal to lowered vehicle miles traveled and congestion. pathways, shaded boulevards, and multimodal transit hubs—integrated with Riyadh's metro extensions—facilitate this accessibility, mirroring outcomes in empirically studied 15-minute models like Paris's where implementation correlated with 20-30% drops in short-trip car use. Sustainability integrates via 25% green coverage, including parks and wadi-aligned linear greenspaces that leverage vegetation for evaporative cooling and shading to offset heat islands, aligning with data indicating 2-5°C reductions in arid-zone applications. , systems, and efficient further embed resource conservation, positioning the district as a low-emission extension of Riyadh's fabric rather than an energy-intensive outlier.

Construction Progress and Timeline

Site Development Phases

Excavation works for the Mukaab site within the development in began prior to mid-2024, focusing on massive earth removal to ensure foundational stability for the 400-meter cuboidal structure. By October 15, 2024, these efforts had achieved 86% completion at the Mukaab and adjacent podium areas, with over 10 million cubic meters of soil excavated to depths necessary for supporting the building's unprecedented scale and volume. This preparatory phase addressed geotechnical challenges inherent to the site's location, prioritizing and groundwork for the substructure amid the project's alignment with infrastructure goals. Engineering oversight for site development is provided by , appointed in December 2023 to handle masterplanning and structural design integration, ensuring compliance with advanced seismic and load-bearing requirements. By early 2025, broader excavations, encompassing the Mukaab footprint, exceeded 13.5 million cubic meters, reflecting accelerated progress through modular construction techniques and heavy machinery deployment. As excavations concluded in late 2024, the project advanced to substructure phases, including raft foundation works estimated at $1 billion, with contract awards planned imminently as of September 2025 by NMDC Group. This transitions into superstructure erection and eventual interior systems installation, maintaining momentum toward operational readiness by 2030 in coordination with timelines, though detailed interim milestones for assembly remain project-internal.

Projected Milestones and Potential Delays

The Mukaab is targeted for completion in 2030, aligning with Expo 2030 and serving as a centerpiece for the event. commenced in late 2024, with foundation excavation reaching 86% completion by 2024, involving the removal of over 10 million cubic meters of and accumulation of 3 million safe work hours. While specific interim milestones beyond site preparation remain undisclosed in official updates, the project's phased approach prioritizes the core structure within the broader timeline, which has seen the surrounding district delayed to 2040 but Mukaab preserved on its 2030 schedule. Potential delays stem from common giga-project risks, including global disruptions and labor in a region reliant on s, as evidenced by historical slowdowns in Saudi initiatives like . However, these are mitigated by Saudi Arabia's Vision 2030-driven reforms, such as enhanced protections under the Saudi Labor Law amendments since 2021, which have reduced labor disputes and absenteeism rates in sectors by standardizing contracts and oversight. Additionally, integration of technologies in the build process—drawing from precedents in projects like —allows for accelerated prefabrication and reduces dependency on manual labor intensity. Empirical precedents from Saudi giga-projects demonstrate that state-backed funding, via entities like the , enables timelines to outpace private-sector equivalents, where financing constraints often extend durations by 20-50%. For instance, Neom's linear city component, announced in 2017 with a multi-decade horizon, has advanced foundational despite scaled-back elements, contributing projected GDP impacts by 2030 through parallel execution of modules rather than sequential delays. Unsubstantiated skepticism regarding feasibility overlooks this model, where sovereign resources have historically compressed construction cycles, as seen in the rapid progression of Riyadh's from concept to partial occupancy within a decade. Thus, while external shocks could impose slippage, the Mukaab's trajectory reflects a pattern of adaptive acceleration grounded in fiscal commitment over market volatility.

Reception and Controversies

Architectural and Innovative Praise

The Mukaab has garnered endorsements from industry leaders for its unprecedented scale and integration of advanced technologies, positioning it as a redefinition of urban architecture. Measuring 400 meters on each side, the cube-shaped structure will encompass 2 million square meters of floor space, surpassing existing supertalls and enabling it to host the world's largest immersive attractions, such as holographic displays and AI-powered environments. This engineering ambition draws praise for blending traditional Najdi geometric motifs with modern innovations, creating a "technological marvel" that merges reality with digital immersion. A key endorsement comes from the August 2025 strategic partnership with Falcon's Creative Group, a U.S.-based firm, to develop cutting-edge interactive experiences within the Mukaab, including immersive attractions that leverage AI and . Falcon's has highlighted the project's potential to deliver "groundbreaking and innovative ," underscoring the feasibility of its tech-driven vision through collaborative expertise in theme park and media integrations. Additional alliances, such as with Alat for vertical transport technologies, further affirm industry confidence in the Mukaab's structural and operational innovations. Proponents emphasize the Mukaab's alignment with economic diversification goals, projecting contributions of over $51 billion to Saudi Arabia's non-oil GDP through multipliers and job creation. The structure is expected to generate approximately 334,000 jobs, supporting Vision 2030's targets for to comprise 10% of GDP and create 1.2 million sector-wide positions by enhancing Riyadh's appeal as a global destination. These data-driven projections highlight endorsements of the project's role in fostering high-impact industries via scalable urban experiences.

Religious and Cultural Criticisms

The Mukaab's cubic form, measuring 400 meters on each side, has elicited religious criticisms primarily for its visual resemblance to the , the cube-shaped structure at the center of Mecca's that serves as the focal point of Muslim prayer and pilgrimage. Announced in February 2023 as part of Riyadh's development, the project prompted immediate backlash on platforms from Muslim commentators worldwide, who accused Saudi authorities of and intentional mockery of Islam's holiest site. Critics, including writers in outlets like Muslim Skeptic, argued that erecting a massive secular complex in this shape dilutes the Kaaba's unique sanctity, with some labeling it a symptom of Vision 2030's secularizing push under Crown Prince . Saudi officials and supporters have rebutted these claims, asserting that the design draws inspiration from Najdi architectural traditions—such as the mudbrick cubes common in central Arabian heritage—rather than any religious imitation. The term "Mukaab" simply translates to "cube" in , and project proponents, including influencer Abdullah Al-Bander, have dismissed linkage to the as "extremist thought" rooted in theories, emphasizing the structure's role in cultural enrichment through immersive attractions like holographic theaters and retail spaces that celebrate Saudi identity without religious connotation. These debates reflect wider tensions in between rapid modernization and religious conservatism, where Vision 2030 initiatives—such as lifting bans on cinemas in 2018 and hosting events like —have faced similar accusations of eroding Islamic traditions but empirically expanded the sector's GDP contribution from near zero to over 1.7% by 2023, drawing millions in revenue while maintaining core religious prohibitions. Defenders argue such projects foster economic diversification without undermining faith, pointing to the absence of any official endorsement of sacrilegious intent and the project's compliance with Islamic guidelines on architecture and public morality. Nonetheless, the controversy persists among conservative voices, who view the Mukaab as emblematic of a broader cultural shift prioritizing spectacle over spiritual primacy.

Feasibility and Environmental Debates

The unprecedented scale of the Mukaab, measuring 400 meters on each side and equivalent in volume to approximately 20 Buildings, has prompted analyses questioning its constructability, particularly regarding structural integrity, loads, and foundation stability in Riyadh's seismic and sandy terrain. Early 2023 assessments highlighted the need for innovative solutions, such as advanced modular construction and high-strength materials, to mitigate risks associated with such mass. However, ongoing site work counters these concerns, with excavation at the Mukaab and podium sites reaching 86% completion by October 2024, involving the removal and repurposing of over 10 million cubic meters of earth, demonstrating logistical feasibility through heavy machinery deployment and phased earthworks. By October 2025, further progress included over 14 million cubic meters excavated, advancing to enabling works without reported major halts. Environmental debates center on resource demands in Riyadh's arid climate, where annual averages under 100 mm and depletion poses systemic risks. Critics argue the Mukaab's enclosed volume and climate-controlled interiors could exacerbate through cooling and needs, potentially conflicting with Saudi Arabia's net-zero ambitions under Vision 2030. Project plans incorporate verifiable mitigations, including a closed-loop water system for recycling and efficient usage targeting reduced consumption compared to conventional high-rises, supplemented by Riyadh's broader expansions yielding over 5 million cubic meters daily. These measures, when benchmarked against sprawling urban developments, yield lower per-capita water footprints due to and tech integration, though long-term efficacy depends on operational data absent as of 2025. Labor feasibility intersects with Saudi Arabia's reliance on migrant workers for megaprojects, where pre-2020s kafala sponsorship enabled exploitation claims including wage theft and passport confiscation, amplified by advocacy groups. Reforms since 2021, culminating in the June 2025 abolition of kafala for a contract-based model allowing job mobility without employer exit visas, have reduced such incidents, with a new National Policy on forced labor emphasizing rights enforcement. While unions persist in alleging abuses on sites like , verifiable compliance data from 2024-2025 inspections shows declining violations, offsetting earlier hyperbole lacking granular project-specific evidence.

Anticipated Impacts

Economic and Developmental Outcomes

The Mukaab is projected to inject approximately SAR 180 billion (about $48 billion USD) into Saudi Arabia's non-oil gross domestic product (GDP), supporting the kingdom's efforts to diversify away from hydrocarbon dependence. This capital infusion stems from the structure's 2 million square meters of total floor space, encompassing commercial, retail, leisure, and cultural facilities designed to generate sustained revenue through tourism, hospitality, and consumer spending. Construction and operational phases are expected to create around 334,000 jobs, with initial building efforts employing up to 900,000 workers, thereby stimulating short-term employment in labor-intensive sectors like engineering and logistics. As a centerpiece of the development, the Mukaab aligns with Saudi Vision 2030's benchmarks for economic transformation, including targets for to comprise 10% of GDP by 2030 through attracting 150 million annual visitors nationwide. Its integration of advanced digital technologies—via partnerships with Public Investment Fund-backed firms—positions it to foster tech hubs focused on immersive experiences, such as volumetric displays and smart infrastructure, thereby drawing (FDI) in innovation-driven industries. This causal pathway—large-scale investment yielding iconic assets that signal openness to global capital—mirrors Dubai's strategy, where projects like the and have elevated non-oil GDP contributions from and real estate to over 30% of the emirate's economy, validating high upfront capital's returns via amplified FDI inflows exceeding $20 billion annually in recent years. Empirical evidence from Dubai's model underscores megastructures' superior (ROI) compared to incremental , as concentrated spectacles generate network effects in branding and visitor multipliers: Dubai's sector now sustains over 7% annual non-oil growth, with iconic builds recouping costs through exponential revenue from 17 million visitors pre-pandemic, far outpacing diffuse developments in per-square-meter yield. Saudi projections for the Mukaab anticipate similar dynamics, with its 9,000 hotel rooms and 1.8 million square meters of leisure space poised to capture high-value experiential , reducing oil's GDP share from over 40% toward Vision 2030's sub-20% goal.

Social and Cultural Transformations

The Mukaab, as the centerpiece of the development, is designed to integrate residential, , and cultural spaces within a single structure, fostering greater social interaction among Riyadh's residents in line with Saudi Arabia's Vision 2030 reforms aimed at building a vibrant society. This mixed-use approach includes over 80 state-of-the-art venues inside the cube, alongside proximity to mosques, parks, and healthcare facilities within a 15-minute walk for inhabitants, promoting community cohesion without relying on car-dependent segregation. Such planning aligns with post-2017 social liberalizations, including the allowance of public concerts—such as the first major event in that year—and the 2018 decree permitting women to drive, which have incrementally expanded public leisure options while upholding core Islamic prohibitions on alcohol and mixing in private settings. By hosting festivals, cultural events, and immersive experiences like 3D holograms, the Mukaab is projected to position as a global cultural destination, attracting international visitors to experiences that blend Saudi heritage with modern innovation, much as the festival has drawn over 20 million attendees annually since 2019 without documented erosion of traditional values. Developers emphasize the structure's name, derived from roots evoking the Kaaba's cubic form and symbolizing generosity and hospitality, as a deliberate nod to Islamic cultural continuity amid technological advancement. This contrasts with critiques portraying such projects as ; empirical patterns from Vision 2030 initiatives, including sustained enforcement of Sharia-based norms alongside rising female workforce participation to 37% by 2023, indicate a pragmatic evolution that preserves while enabling cosmopolitan exposure. The influx of global tourists—targeted to reach 100 million annually by 2030 under broader national goals—via Mukaab's is anticipated to enhance ' intercultural adaptability, evidenced by similar boosts in Dubai's mixed-use where expatriate inflows correlated with 15% rises in local youth engagement in arts without shifts in adherence to conservative . Yet, official projections stress that will remain family-oriented and compliant with Islamic guidelines, countering unsubstantiated fears of by prioritizing that reinforce national pride and unity, as seen in planned gatherings fostering communal identity.
