Box-like volumes create the monumental form of this functionalist former laboratory – for sale in the Netherlands.

The Wageningen building was designed in the 1950s by Dutch architects F E Röntgen and A Kruidhof as an earth science laboratory for the Dutch Geodesy Association. It was later used as offices, and in 2001 its top floor was converted into a three-bedroom penthouse flat.

Built in functionalist style, the white brick property features sharp vertical and horizontal lines, extensive glazing and a flat roof that tilts upwards. A watchtower soars above its roof while an original concrete mural depicting organic shapes decorates a side elevation.

The 5,274 sq ft penthouse apartment, which occupies the former laboratory, has a glass wall spanning the entire building, with views out to the Rhine river. An open space runs between the partitioned living rooms and the glazed elevation, which give a sense of the room’s original volume.

On sale with Netherlands Sotheby’s International Realty for €3.55m, the building also has ground, and first-floor office rooms that could be let commercially or be a future adaptive reuse project.
