The renovation and remodeling of the partly monumental building complex of the Hoogheemraadschap van Delfland was realized by the architect’s office “Mecanoo Architects”. This has led to a more sustainable office building with clear lines, lots of light, flexible workplaces and a clear appearance. The view of the surrounding historic buildings through the glass façade made with the Stabalux screw tube (SR) contributes significantly to the orientation and perception of the building.
