The Ministry of Transport, Public Works and Water Management asked ZJA to design the pumping-engine building at traffic junction Raasdorp in the polder Haarlemmermeer which lies four meters below sea-level.
The old pumping-engine stood in the way of the new highway A5, also designed by the architects ZJA.
The design of the pumping-engine building is based on simplicity. The design is basically no more than a sheet of perforated steel covering the pumping-engines. Artificial light provides in a special effect at night: the silhouette of the pumping-engines is visible through the perforations.
