To the right of the antechamber is the burial chamber; to the left is another small room, a Serdab.
The earliest serdab of this type is found in the pyramid of Menkaure, but is was during the reign of Djedkare Isesi that it became a part of the standard pyramid layout.
In his tomb he is described as a hereditary prince, count, sealer of the king of Lower Egypt (jrj-pat HAtj-a xtmw-bjtj) and on a statue found in his serdab (and now located in Hildesheim), Hemiunu is given the titles: king's son of his body, chief justice and vizier, greatest of the five of the House of Thoth (sA nswt n XT=f tAjtj sAb TAtj wr djw pr-DHwtj).
