Transformation of the  Insulinde office building, Schimmelpennincklaan Den Haag 

The Insulinde office building designed by Leo Falkenburg in 1917 for the Dutch East Indies Union (National Monument) has been transformed into eight very different apartments.

The cramped original floor plan has been opened up, creating long sightlines in the building. A patio in the roof construction has been created above the glass ceiling in the hall to provide the attic with natural light and outside space. This creates a light and spacious penthouse, in a residual space that was previously used as storage. A sustainability upgrade has also been made: the use of double glazing in the original steel frames and the application and special very high-quality thin insulation boards in such a way that the original detailing of moldings, tiling and paneling was not affected.
