Amsterdam is known for its narrow houses and alleys. In the Jordaan there used to be even smaller alleys in between the houses. These alleys often lead to run down accommodation for the poorest of the poor, hidden behind the rows of houses facing the main streets. When the ‘front row’ houses were expanded most of these alleys vanished, and with them the hidden houses. The Dolfijnengang, one of the alleys on Westerstraat, gave access to house numbers 56 to 68. Which is why today there’s a number-gap between number 54 and 70. Natwerk, known for creating stuff just for the fun of it, recreated the missing houses on the Westerstraat.
