Chambers of Mastaba k1 Beit Khallaf
The stairway (1) becomes the corridor (2) which widens and makes the stone walled chamber for the deceased (3). Wells from above (in grey) were for later offerings and all ended above the rooms. The tomb tried to resemble the owner's house from his life on earth, and by the grave chamber (bedroom) were likely facilities like closet (4), bathroom (5) and lavatory (6).
