The Richard C. Smith House is a small Usonian home designed by Frank Lloyd Wright and constructed in Jefferson, Wisconsin in 1950. It is one of Wright's diamond module homes, a form he used in the Patrick and Margaret Kinney House, the E. Clarke and Julia Arnold House and a number of other homes he designed in the late 1940s and early 1950s. Wright seems to have started the design at the huge oak which was already on the lot. His blueprints show that he drew an imaginary triangle around the tree, then oriented the diamonds, terrace and house around it.
