One Marina Boulevard is conceived as a gateway to Singapore’s new downtown, serving as headquarters to the National Trades Union Congress (NTUC) and as an office space for multi-national corporations and local companies. The 32-storey building is sited at the edge of the city’s financial district and adjacent to the public promenade that lines Marina Bay. As a testament to the enduring economic benefits of the tripartite compact between the NTUC, the employers and the government, the architects sought to attain a high degree of transparency and connectivity with the public spaces of the surrounding downtown, an expression of the programme’s civic nature.
An open-plan ground floor has been designed to engage the site’s high-frequency public circulation. It features a porous lobby and covered walkways with retail spaces at the basement level and a cafe on the second-storey mezzanine — conduits to attract visitors inward. To complement the porosity of the ground level, high-transparency, green curtain walls compose the facade above.
Formally, the block tower is punctured on three of the building’s elevations by communal sky terraces. The facade emphasises verticality by means of articulated linear fins, a characteristic accentuated by structural columns revealed at the terrace voids.
This verticality is reflective of internal programme organisation, which is layered into two stacked zones: the lower zone consists of NUTC offices and shared facilities including a 600-seat auditorium, meeting rooms, retail space, and a multi-storey carpark. The upper zone begins at level 16, where floor plates are divided into two column-free office spaces joined by a central services core.
