Completed in 1986, Darul Aman Mosque is one of nine new mosques designed and built by the Housing and Development Board (HDB) to cater for the religious needs of the island's Muslim community. These mosques are not intended as prayer houses only, but also accommodate other activities ranging from religious classes to welfare programmes set up for the benefit of the ummah. The project was financed by the Mosque Building Fund Scheme, a body established in 1975, which manages money contributed by Muslims.
The mosque consists of a main prayer hall preceded by a courtyard, flanked by two smaller courtyards. Two additional prayer halls with a classroom are placed on either side of this main core. The larger courtyard can serve as prayer space. The mosque is laid out symmetrically along an axis determined by the entrance and the qibla wall. The two smaller courtyards are used to separate the main prayer hall from the ancillary facilities such as the classrooms and offices, and also allow for natural ventilation throughout the building. The overall design is based on local Malay architectural forms, and features traditional pitched roofs and timber construction, in the present instance, however, these forms are executed with modern materials and current construction techniques. From the structural elements to the lattice screens, a simple rhombic motif is applied throughout the building and conveys a visual unity to the entire mosque.
