	The building was formerly a farm house constructed in about 1900–1910 and ceded to the National Museum of Kenya in 1965 by the owner, the late Mrs. Selfe. The building is rectangular in plan with a veranda along the south façade. It is entered through a 4.8 m wide straight stairway of 5 steps onto a veranda, and then into the main gallery through a protruding porch that forms part of the central space of the building. Inside, this building is divided into three chambers/galleries, the central being the largest. At the back, the building is abutted by two chambers which are used as the Curator's and Education offices respectively.
