Architecture of G2378
The mastaba of Senedjemib Mehi, eldest son of Senedjemib Inti, sits on an independent site on the north
side of the paved court of G2370. According to Reisner 2378 was built soon after G2370 and before G2374. At that time G2375 was in place with  its open court facing west. G2378 was built over the eastern end of the court of G2375.
Moreover, its northern part overlay older constructions of mud brick represented by a series of rooms.
The mastaba received two additions on the west, G2376 and G2377. It was excavated by the Harvard–Boston Expedition in December, 1912.
G2378 has a retaining wall or casing of different types of  masonry and therefore belongs to Reisner’s type VIII a(2) or (3). The chapel is of the multiple room type (7), and consists of a pillared portico (Room I) and two interior rooms. Room II is an east–west corridor
or anteroom, south of and parallel to the east–west offering room (Room III). It has a slot with a serdab behind its west wall.
The mastaba measures 23 x 12 m and has an area of 276 sq. m. The proportion of the length of the mastaba to the width is 1/1.92.
The total floor area is 34.86 sq. m; the relation of the floor area of the chapel to the area of the mastaba is 1/7.91.
