The mosque’s design is Contemporary in appearance and largely open to the outside. The mosque consists of two buildings Assalam Mosque and Al Darwish Abdullah Cultural Centre. The buildings are connected by a gallery and have a patio with fountains between them. The glass minaret of the mosque is 17m high, and the dome is 14m high and 12m diameter.

The mosque consists of two large prayer rooms, a multipurpose room, library, an early childhood area and the offices of the association. The hypostyle prayer hall, with its 20 columns, can accommodate up to 1,500 worshipers, including an upper wing decorated with exotic wood. The use of Sapelli mahogany wood gives resonance and its reddish-brown colour brings warmth and makes the space more convivial. In the large prayer hall, the mihrab is in cedar wood refinedly carved in arabesque with a floral motif. The latter indicates the sacred direction of Mecca – the qibla – towards which the faithful turn to pray and which is the main element in a mosque, because it orients and conditions the shape of the room. The volumes of the building are governed by an order of symmetry and axiality characterized by the purity of forms, the hierarchical succession of spaces and the clarity of the circuits.

The interior of the mosque is decorated with traditional Zellige, made of tiny pieces of clay, carved manually using heavy hammers (menqach), then assembled into a mosaic. Due to its manual manufacture, each zellige tile has imperfections that make it a unique piece. The colours blue, off-white, gold and burgundy, are obtained from a mixture of ore and silica. As for the rest of the decoration, it is limited to arabesque, calligraphy and abstract or geometric shapes.

The building largely favors natural exterior lighting, the dimensions of the glass frames and their distributions allow only very soft light to enter the prayer room, guaranteeing believers a certain tranquility in the accomplishment of their religious duties, after the stress of a day of work. The lighting is reinforced by light fixtures, a finely cut authentic crystal chandelier completes the ornamentation thus playing an important role in the atmosphere and decoration of the room.

From the outside, the 14-metre high dome is supported by a highly resistant glued laminated timber structure, which is clad in a metal covering based on a quartz zinc substrate from the PIGMONTO green range, which changes colour depending on the light. With its imposing volume, the dome is a major element of Islamic architecture, even if its purely liturgical role in the context of a mosque is quite limited, it is used both to indicate the prayer room from the outside and to provide it with volume, sound and light from the inside. the minaret is 17 meters high and made of concrete veil covered with glass blades, equipped with a plasma screen and topped with a crescent moon. Granite was chosen to cover the exterior walls to signify eternity and prestige.
