Planning and development

Site and location

One Raffles Quay occupies a prominent 1.6-hectare site within Singapore's Marina Bay precinct, in the planning area, where the land has been reclaimed from the sea as part of the nation's expansive waterfront reclamation efforts. This positioning allows the development to serve as a vital bridge between the established business district—Singapore's traditional —and the emerging Marina Bay area, including the Marina South extension, thereby enhancing urban connectivity in the heart of the city-state's financial core. The site's strategic location integrates seamlessly with Singapore's public transportation network, straddling existing rapid-transit subway lines and providing direct underground pedestrian access to key stations such as (North South and East West Lines) and (), both within 400 meters. This connectivity underscores its role in the broader , offering sheltered links via networks like Marina Bay Link Mall and The Sail @ Marina Bay to facilitate efficient commuter flow. Geographically, One Raffles Quay is situated at approximately 1.28°N and 103.85°E , placing it amid a cluster of iconic landmarks in the Marina Bay vicinity, including the integrated resort roughly 1 kilometer to the northeast.

Project inception

The development of One Raffles Quay emerged in the early as a speculative Class A project aimed at accommodating the expanding needs of banking and financial corporations, thereby reinforcing Singapore's ambitions as a premier financial hub in . Conceived during a period of economic recovery following the 2001 downturn, when Singapore's GDP growth shifted from -2% that year to stronger expansion thereafter, the initiative sought to create high-quality space in the nascent Marina Bay district to attract amid limited supply of premium commercial properties. The project was spearheaded by a consortium of three prominent Asian developers: , Hongkong Land, and Keppel Land International, who recognized the site's potential to bridge Singapore's with the emerging downtown area. This partnership formed the core ownership structure, enabling a collaborative approach to the development's initial phases, including feasibility studies and conceptual planning focused on financial sector tenants. A pivotal milestone occurred in March 2001, when the (URA) tendered the 1.6-hectare reclaimed site for development, selecting the consortium's bid of S$462 million after a competitive that emphasized innovative urban integration and features. The URA's approval of the granted initial planning permissions, setting the stage for detailed design and construction preparatory works, with the site acquisition formalizing the project's launch despite prevailing economic uncertainties.

Architecture and design

Overall concept

One Raffles Quay was designed by the New York-based architecture firm (KPF), which aimed to create a structure embodying timeless professional elegance while seamlessly integrating with Singapore's urban skyline. The design philosophy emphasized enhancing the pedestrian network and reinforcing the Downtown Core's emerging street patterns, positioning the development as a pivotal element in the city's architectural landscape. This approach sought to elevate the visual harmony of the area, contributing to Singapore's reputation as Southeast Asia's financial capital through sophisticated, modern lines that avoid ostentation. At its core, the conceptual goal of One Raffles Quay was to serve as a landmark bridging the established business district with the burgeoning Marina Bay developments, fostering greater connectivity in Singapore's central business hub. By spanning reclaimed land and subway infrastructure, the project was envisioned as a transitional node that links these key areas via enhanced pedestrian pathways, including travellator systems at elevated levels, thereby promoting fluid movement and urban cohesion. This visionary linkage not only supports the expansion of financial activities but also underscores the building's role in shaping a dynamic, interconnected commercial environment. Aesthetically, the design features a striking glass facade that allows natural light to permeate the structure, creating a luminous and transparent presence amid the surrounding high-rises. Complementing this is a prominent podium base that facilitates public access through an open plaza and arcade, with an eight-story-high lobby in the north tower serving as an inviting urban gesture. These elements, including a lantern-like crowning on the taller tower, contribute to the building's elegant silhouette and its integration into the skyline, prioritizing accessibility and visual appeal for both occupants and the public.

Tower specifications

One Raffles Quay comprises two towers integrated with a shared multi-story that connects them at the base. The North Tower rises 50 storeys to a of 245 metres, offering approximately 763,000 square feet (70,900 square metres) of net lettable area across its floors, with typical plates measuring 18,000 square feet. These floors feature a column-free , supported by a planning grid of 1,200 mm and a finished floor-to-ceiling of 2,750 mm, enhancing spatial flexibility for occupants. The South Tower stands at 29 storeys and reaches 140 metres in height, with larger typical floor plates of 30,000 square feet that are also entirely column-free. Together, the two towers deliver a total of about 1.3 million square feet (120,000 square metres) of premium , tailored for high-density financial and professional use. A key aspect of the internal structural layout is the innovative transfer system integrated into the central core, which distributes loads effectively around the underlying Mass Rapid Transit infrastructure while enabling the expansive column-free interiors. This system, paired with an outrigger-braced framework, allows for unobstructed floor areas and optimal load transfer across the towers' heights. The towers link via the shared podium and an adjacent through-block plaza, providing ground-level connectivity without upper-level bridging elements.

Construction

Engineering innovations

One Raffles Quay's structural engineering, led by the Meinhardt Group, addressed significant challenges posed by the site's location on reclaimed land in Singapore's Marina South district, where soil conditions are inherently unstable due to marine clay deposits and historical reclamation efforts. The design incorporated large-diameter piles driven through bouldery clay layers to ensure foundation stability, with rigorous quality controls to limit cumulative ground movement to approximately 15 mm, thereby protecting the integrity of underlying infrastructure. This geotechnical approach was essential for supporting the dual-tower complex, which spans 1.3 million square feet of office space across a 1.14-hectare site reclaimed from the sea. A key innovation was the transfer truss system developed for the 50-storey North Tower, the first worldwide application of such a system in a high-rise building to span active tunnels without operational disruption. Meinhardt pioneered a central box core acting as the primary transfer structure, combined with mega steel trusses and raking columns to redirect loads from the east and west perimeter columns over the shallow-depth subway lines of . This hybrid steel-concrete composite system minimized the building's overall weight, enhanced lateral stability against wind loads via trusses and floors, and enabled expansive column-free floor plates of up to 30,000 square feet in the South Tower. The project also integrated Singapore's first commercially applied district cooling system (DCS), centrally managed by , to supply chilled water for air-conditioning across One Raffles Quay and adjacent Marina Bay developments. This system eliminates individual building chillers and cooling towers, utilizing (TES) tanks beneath the to chill water during off-peak hours with lower-cost electricity, then distribute it via a 5 km underground piping network during . By centralizing production, the DCS reduces energy consumption, construction risks, and effects while providing reliable cooling to over 929,000 square meters of space in the district.

Timeline and completion

Construction of One Raffles Quay commenced with in June 2002, under the main awarded to . Early phases focused on foundational work, which presented significant challenges due to the site's location on reclaimed land straddling active tunnels; specialized sub-structure efforts, including piling and stabilization over these lines, to support the dual-tower complex. Tower erection followed, with the 50-story North Tower and 29-story South Tower rising progressively amid innovations like the transfer truss system to navigate underground constraints. The project reached substantial completion in 2006, marking the official opening of the complex as a premier office destination. Initial occupancy was swift, with the building 100% pre-leased to , including major banks that began operations shortly after handover.
