The structure consists of a rectangular wall oriented north-south and measuring about 650 by 350 metres. The walls consist of two outer walls made of roughly hewn limestone about 15 metres apart; the space between them is filled with crushed stone, gravel and sand. In the northwestern corner, the walls survive to a height of 4.5 to 5 metres (over 15 courses of stone). The style of construction suggests an original height of around 10 metres. In the south the state of preservation is clearly worse than in the north. Since the west wall of the structure is 30 metres shorter than the east, the south wall probably consisted of two parallel walls forming an entranceway. This pattern recurs in the larger funerary complex of Djoser's step pyramid.
