On an industrial site in Utrecht called De Uithof a new building (6000 m3) appeared, to increase the capacity next to two existing power stations. The size and construction of the building are largely determined by the technical requirements. The building is completely covered in order to keep noise pollution to a minimum. A skin of steel is folded over the machinery and the giant filters and dampers. Its striking form is emphasized by the self-supporting steel skin and gives the building a sculptural role in the landscape.
