Het Schip is a block of dock workers' flats with a tower nobody can enter. The tower at the sharp end has no stairs, no floors and no door: it is a hollow wooden frame clad in roof tiles. Michel de Klerk put it there because the corner needed a vertical mark, and for no other reason. It went up in 1919 and holds 102 flats. Councillors asked whether this was too much for working people.
The housing alderman Floor Wibaut answered that workers were owed buildings that were good and also beautiful, and the block went up. Walk round the outside and the wall keeps changing: the 102 flats were built to eighteen different plans, so windows, doors and balconies almost never repeat. Neighbours call the rounded corner flats the cigars. It is still social housing, and you can circle it and cross the courtyard at any hour. The museum has the old school and post office on the Oostzaanstraat side, where one flat is furnished as a 1920s tenant would have had it.
