Papaverhof
The Papaverhof is a housing complex in The Hague designed by Jan Wils which was built from 1919 to 1921. This complex became his breakthrough as an architect and today it is a Rijksmonument that was selected for the Top 100 Dutch heritage sites. The complex includes 128 middle-class homes built in horse-shoe fashion around a sunken garden. It was restored several times, in 1958, in 1971, in 1989, and most recently in 2006.
Besides the communal garden in the middle, each home has its own yard with enclosing wooden fence and cement flower pots in matching architectural style.
