Villa Müller (Nad Hradním vodojemem str. 642/14), located in Prague's district of Střešovice, is the house that was designed originally by Adolf Loos for Mr. Frantisek Müller and his wife, Milada Müller. The villa built in 1928-30 is considered to be the chef-d'oeuvre of the international architectural avant-garde. The construction of the villa is strictly functionalist. It's evident in the multi-level parts of individual rooms.
