Slappe Zwanen is a commissioned project by Projectbureau Ypenburg in collaboration with STROOM Den Haag and 7×11 Ypenburg.
Artcommission Ypenburg commissioned eight artists to produce artworks especially for the Ypenburg project.
The inhabitants of Ypenburg could choose, in consultation with the art commission, the artworks they wanted to have on their houses.
In the field of public art projects Kunst aan Huis Ypenburg is the first project in such a large scale in which the inhabitants of the location are involved in choosing the artworks.
Participating artists: Jeroen Allart, Arja van den Berg, Krijn Christiaansen/Jeroen Bruls, Tom Claassen, Douwe Halbertsma, Ingrid Mol, Bert van Ommen and Theo Schepens.

The Slappe Zwanen are placed on 54 locations in Ypenburg.
