The queen's pyramid originally stood 16.8 metres (55 ft) high with a slope of 52°, similar to that of Userkaf's, with a base 26.25 metres (86.1 ft) long. The core of the pyramid was built with the same technique as the main pyramid and the cult pyramid, consisting of three horizontal layers of roughly hewn local limestone blocks and gypsum mortar. The core was undoubtedly covered with a fine Tura limestone outer casing, now removed. In fact, the pyramid was so extensively used as a stone quarry in later times that it is now barely distinguishable from the surroundings and its internal chambers are exposed.
The entrance to the substructure is located on the pyramid's northern side and consists of a descending passage leading to a T-shaped chamber. This chamber was located under the tip of the pyramid and is oriented on an east-west axis like the rest of the queen's pyramid complex. It has a pented roof made of large limestone blocks, a construction technique common to all pyramid chambers of the 5th dynasty. The substructure is thus a scaled-down version of Userkaf's without the magazines.
