Willem Wissenplein 1, The Hague, The Netherlands, 2596 BE
The Nirwana-Flat is the oldest block of apartments in the nation. Built in a modernist art deco style, the apartments put most dwellings built nowadays to shame, yet were a difficult sell when they were built. It's hard to believe people once were skeptical of living in these spacious, comfortable homes, as now they are some of the most prized addresses in the city. The complex sits just across the street from the Haagse Bos.
