Although Bruce Goff (1904-1982) is very famous in the Chicagoan architecture milieu, he is not so well known (I think) outside of the United States. His Bavinger House (1955) in Norman Oklahoma is however a very interesting hybridization of high level of craft (see the joint between the glass and the stones) with a more deliberate approximation (see the net handrail or the polyurethane volumes).
This house is only the most expressive manifesto of Goff’s architecture but there are several other buildings that definitely deserve attention.
