The building is listed as a Rijksmonument.
The architect Willem Molenbroek designed the 10-storey building, at the time an unprecedented height in Europe.<ref name=Rijks/> The site at Wijnhaven 3 is just 1 m above sea-level and skeptics claimed that the soft soil of Rotterdam would be unable to adequately support the building, so before construction could properly begin, 1000 piles were driven into the ground to support the building's weight. The building is constructed from iron and steel and cement, and includes two thick interior walls which increase the building's strength. Unlike many other contemporary buildings of the time, wood was not a significant construction material due to the fear of fire. The building cost 127,900 Dutch guilders.
It was also one of the few buildings in central Rotterdam to survive the German bombing campaigns of World War II. Template:Rijksmonument
