The two tiered mosque has a rectangular plan. The Ottoman prayer hall faces towards the south. It has a flat paved roof topped with 27 sliding domes on square bases. Holes pierced into the base of each dome illuminate the interior. The roof is also used for prayer during peak times, when the domes slide out on metal tracks to shade areas of the roof, creating light wells for the prayer hall. At these times, the courtyard of the Ottoman mosque is also shaded with umbrellas affixed to freestanding columns. The roof is accessed by stairs and escalators. The paved area around the mosque is also used for prayer, equipped with umbrella tents. Sliding Domes and retractable umbrella-like canopies are designed by the German architect Mahmoud Bodo Rasch and his firm SL Rasch GmbH and Buro Happold.
