The museum building, an architectural attraction in its own right, was Frank O. Gehry's first building in Europe, realised in cooperation with the Lörrach architect Günter Pfeifer. Together with the museum, which was originally just designed to house Rolf Fehlbaum's private collection, Gehry also built a more functional-looking production hall and a gatehouse for the close-by Vitra factory.
Although Gehry used his trademark sculptural deconstructivist style for the museum building, he did not opt for his usual mix of materials, but limited himself to white plaster and a titanium-zinc alloy. For the first time, he allowed curved forms to break up his more usual angular shapes. The sloping white forms appear to echo the Notre Dame du Haut chapel by Le Corbusier in Ronchamp, France, not far from Weil.
