The Narkomfin-Building is a Heritage Site of outstanding European value. The Constructivist Narkomfin housing group in Moscow represents a key monument in Russian Avant-garde architecture. The communal house of Mojsei Ginzburg and Ignaty Milinis is a world-famous chef-d'oeuvre of the modern movement and stimulated the international pursuit of social housing reform in the 20th century. It is part of our common European heritage and worthy of nomination for the UNESCO World Heritage List. Its conservation and restoration is of common European interest and concerns all of us.
