Architect Jan Willem Buijs (1889-1961) is best known for his much-discussed design for De Volharding on the Grote Markt in The Hague. He designed the office building as an innovative light monument: the building has a reinforced concrete skeleton, which made it possible to install non-load-bearing facades. The parapets were given high light boxes, which were provided with advertising texts by placing zinc letters and numbers in the boxes.
