Some of the most extraordinary buildings of the Soviet era are those that sprung up as a result of the New Economic Plan, a period of economic and artistic flowering.
Constructivist buildings, such as Melnikov's House (1927) and Narkomfin (1928), are unappreciated by the mayoral regime, yet they rate among the best avant-garde buildings in the world. Only three 20thcentury buildings in Moscow are protected, all of them at the lowest level. Narkomfin is the most at risk of these buildings. Despite the filling-in of the open ground floor in the 1930s, the original form of the building is entirely legible. It is still partially inhabited, but is falling apart at the seams.
