Considering these values, if the building really was a step pyramid, it would have had a base larger than that of the famous Step Pyramid of Djoser, while in the case of a mastaba, it would have exceeded in size the already considerable Mastabet el-Fara'un of Shepseskaf. Hypogeum From the North face of the structure, an horizontal corridor, whose entrance is at ground level, goes straight into the center of the structure. The corridor then continues to a descending gallery, lined with limestone, topped by eleven arches and reinforced with pilasters. The gallery finally leads to the burial chamber, placed in the center of the building's base. The rectangular burial chamber is located meters under the ground level and measures x . Its walls are made of roughly worked limestone blocks, presumably taken from a nearby, older necropolis of the 6th Dynasty. The hypogeum was found completely empty during the excavations and was certainly robbed and nearly destroyed in antiquity. Consequently, it is impossible to say if anybody had indeed been buried here. The structure of the burial chamber bears many similarities with that of Mastaba K1 of Beit Khallaf, dating back to the 3rd Dynasty. Funerary complex On the North side of the main structure, the ruined remains of a building were found, which may belong to a mortuary temple originally part of the pyramid complex. However, the remains are not sufficient to obtain a reliable reconstruction of the temple. Remains of a portion of a perimeter wall of mudbricks were also found, but they run in an area that is now under the modern village of Dara.
