Moscow, Ovchinnikovskaya Embankment 18-1 (former ministry for economic development). The building was built in stages - a late stalinist core in 1960 (left), a modernist annex in the 1970s (center), and again a pseudo-stalinist annex (right). The facades look similar, but inside it's evident that these are three different buildings.
