Key Information

Background

[edit]

Formerly known as the Tanjong Pagar Centre, the 65-storey, 1.7 million sq ft skyscraper was developed by GuocoLand and designed by Skidmore, Owings & Merrill.[4] It is the headquarters of Guocoland Limited (Singapore) and is the only skyscraper exempted from the height restriction of 280m.[5] Guoco Tower houses the rooftop Urban Park, the Wallich Residence apartment complex, and a hotel by Sofitel Hotels & Resorts.[3] The tower also has a mall, which includes a variety of food options like City Hotpot and Ah Lock & Co. and Aburi-EN.

The development won the 2014 World Architecture News Mixed-Use Award in the Future Projects category,[6] and was shortlisted for the 2015 World Architecture Festival Commercial Mixed-Use Award in the Future Projects category.[7]

History

Planning and Development

The development of Guoco Tower originated from the of a prime site in Singapore's , previously known as the Tanjong Pagar Centre site. In November 2010, GuocoLand Limited successfully bid for the 1.5-hectare, 99-year leasehold site at through a tender process organized by the (URA), with the building agreement signed in February 2011. The site, located at the intersection of Peck Seah and Choon Guan Streets, was acquired for S$1.708 billion, equivalent to S$1,006 per per plot ratio, positioning it as a key opportunity to revitalize the precinct with an integrated mixed-use project. GuocoLand Limited, a of Guoco Group Limited and part of the , served as the primary developer for the project, which carried an estimated gross development value of approximately S$3.2 billion. This ambitious undertaking aimed to create a vertical integrating , residential, , and retail spaces directly above the MRT station, enhancing connectivity and urban vitality in the area. The project's scale and strategic location underscored GuocoLand's commitment to landmark developments that blend commercial functionality with public amenities. In 2011, the URA granted approval for the mixed-use under its planning framework, permitting a maximum height of 290 meters—exceeding the standard 280-meter limit for buildings in —to establish a new while aligning with the authority's vision for a sustainable and pedestrian-friendly . This approval facilitated the project's progression, emphasizing integration with and green spaces. In 2012, GuocoLand appointed Skidmore, Owings & Merrill (SOM) in collaboration with local firm Architects 61 as the lead architects, following an initial design selection process; SOM's expertise in supertall structures was pivotal in shaping the tower's innovative form. The project's visionary approach earned early recognition, including the 2014 World Architecture News Mixed-Use Award in the Future Projects category, highlighting its potential to redefine urban mixed-use developments through seamless integration of diverse functions and public realms. This accolade affirmed the planning and design decisions made in the pre-construction phase, setting the stage for its role as Singapore's tallest building upon completion.

Construction

Construction of Guoco Tower began in July 2013, with serving as the main contractor responsible for erecting the 64-storey mixed-use . The project, part of the larger Centre development, involved constructing a towering structure reaching 290 metres in height on a constrained urban site in Singapore's . Key milestones included the topping-out ceremony in January 2016, marking the completion of the structural frame, followed by the overall structural completion in mid-2016. The engineering firm Arup handled the structural design, overseeing critical aspects such as the foundation and load-bearing systems to support the building's and mixed functions. This included implementing a pile-raft foundation system analyzed through 3D geotechnical simulations to manage soil behavior under heavy loads. One of the primary challenges was integrating a three-level basement, extending 18 metres deep, directly with the existing while coordinating with the adjacent 150,000-square-foot Tanjong Pagar Urban Park. The site's dense surroundings—bounded by roads, heritage shophouses, and operational infrastructure—necessitated careful excavation to avoid disruptions to nearby shallow foundations and transport lines. Arup's design incorporated a belt-wall system and transfer plates to stabilize the stacked office and residential towers above the basements. To address the tight urban constraints, the project employed top-down construction methods, allowing simultaneous building of basements and above-ground levels to accelerate progress and minimize site disruption. This approach, combined with innovative structural solutions, enabled the workforce to complete the core building process within approximately three years despite the complexities of the location.

Architecture and Design

Sustainability

Environmental Design Features

Guoco Tower incorporates advanced energy systems to minimize consumption and promote efficiency. The building features high-performance chillers and cooling towers that achieve over 30% energy savings compared to conventional systems, alongside energy-efficient centrifugal chillers and LED lighting with motion sensors. Photovoltaic panels on the rooftops and integrated into the City Room canopy generate renewable energy, contributing up to 2% of the development's needs while facilitating east-to-west air movement. Rainwater harvesting systems collect and store water for landscape irrigation, supporting overall energy reduction targets that have resulted in a 7% decrease in consumption from 2019 levels. As of FY2025, energy consumption decreased by an additional 4% compared to FY2024, following optimizations from a December 2024 energy audit of the chiller plant and air-conditioning systems. The tower employs green materials to reduce environmental impact during construction and operation. Interiors utilize low-VOC and formaldehyde-free paints and adhesives to improve , while recycled materials, including concrete with recycled content, are incorporated into structural elements. Landscaping features native plant species across eight elevated gardens and the Urban Park, enhancing and integrating over 8,000 square meters of greenery into the design. Water management practices focus on conservation and to achieve substantial reductions. A three-step includes harvesting rainwater and condensate water, a dual-pipe network for non-potable uses, and high-efficiency, low-flow sanitary fittings, leading to a 39.3% drop in consumption from 2019 levels. These measures target over 35% overall savings through efficient fixtures and . As of FY2025, use intensity decreased by 3% to 1.45 m³/m² compared to FY2024. Ventilation systems emphasize natural airflow to lessen reliance on mechanical cooling.
