This new mosque and social center erected in a residential suburb of Singapore on an irregular, sloping site between a major highway and a secondary road. A square modul of 3.5 m is set out along the central axis of the plan, orientated to the direction of Mecca. The main elements of the project are conceived within this grid of modules. The minaret, a 24 m high tower surmounted by a bulbous dome, is situated to one side of the main building mass (prayer hall, courtyard, and ablution hall). The same module is found in the elevations. Each square is indicated by the exposed white concrete frame, enclosing an arched brick window opening. The basement of the complex houses a library and work room.
