The corridor in turn led into a hallway stretching left and right, forming a T-shaped chamber arrangement.

It is noteworthy to mention that the terrain of Dahshur provided a rather soft and loose ground, a circumstance that forbade any deeper underground chamber building and thus forced the tomb builders to create chambers inside the mastaba and over ground level.

A similar case happened during the construction of the Bent Pyramid, when the walls and ceilings of chambers under ground level started to form cracks.

A special feature of Netjeraperef's offering chapel are the two stelae (once set each left and right of the altar), of which one is nearly completely preserved.

One of the stelae, however, was stolen during restoration work in Middle Kingdom period and re-used as a door frame for Sneferu's valley temple at Meidum.
