One Raffles Place Tower One, formerly known as OUB Centre, was designed by renowned architect, the late Kenzo Tange. Standing tall for more than three decades and counting, the tower has been consistently included in the list of top skyscrapers in the world.

The building, consisting of two triangular structures, provides tenants with regular column-free office space to ensure maximum efficiency in planning and usage. The dramatic entrance is presented by an eight-storey high cutaway, coupled with skylights and other lighting effects to impress all who enter the building.

Tower One has attained the Green Mark Gold Award certified by the Building & Construction Authority (BCA) in recognition of the energy efficiency and environmentally sustainable design.
