Kurokawa’s building is truly exceptional in the Netherlands. This is primarily because of its remarkable design, but also because of the extremely advanced materials used.
An example is the use of titanium for the roof and the wall facing the Rietveld building. Kurokawa used titanium in earlier designs, partly because it is so reliable. It had not been used before in the Netherlands for a museum.
Another high-quality material is the deer brown stone. It is used for the elliptical facade on the Museumplein side. Great technical skill was required to make this material follow the curve of the facade. This use is unique in Europe.
