The article considers the problem of design of a smart apartment as a new level of historical development of small housing. Various aspects of housing cell formation are considered in the scientific works of Bachynska L.G., Gnesya I.P., Gnat G.O. etc.The history of furniture development with the signs of transformation was studied by scientists: Bosyi I.M., Mygal S.P., Z. Dyachun., Vergunova N.S.
