For NedTrain, a company specialized in train maintenance, ADP architecten designed a large-scale, modern extension for its oldest and largest workspace. Since August 2007, this workshop additionally had become responsible for the maintenance of the High-Speed Train and as such its workspace needed to be enlarged and modernized. ADP was commissioned to make the situation more coherent and to expand it with a so-called 'pit rail' resulting in the current expansion of the existing workshops. The new buildings are situated partially between the existing halls. Both its interior and exterior is modern, light and transparent. The building lets in as much daylight as possible through the walls and especially the roof. The later being a modern version of the old saw tooth roof, composed of diagonal planes that are flat and curved. This reinforces the desired lightness of the design.
The design was awarded with the Staalprijs 2008 (Steel Prize).
