Ventilation and the play of light make this neighbourhood mosque a refuge for spirituality. After a difficult life and the loss of her husband and near relatives, the client donated a part of her land for a mosque to be built. A temporary structure was erected. After her death, her grand-daughter, an architect, acted on her behalf as fundraiser, designer, client and builder to bring the project to completion. In an increasingly dense neighbourhood of Dhaka, the Mosque was raised on a plinth on a site axis creating a 13-degree angle with the qibla direction, which called for innovation in the layout. A cylindrical volume was inserted into a square, facilitating a rotation of the prayer hall, and forming light courts on four sides. The hall is a space raised on eight peripheral columns. Ancillary functions are located in spaces created by the outer square and the cylinder. The plinth remains vibrant throughout the day with children playing and elderly men chatting and waiting for the call to prayer. Funded and used by locals, and inspired by Sultanate mosque architecture, it breathes through porous brick walls, keeping the prayer hall ventilated and cool. Natural light brought in through a skylight is ample for the daytime.
