The home, one of Wright's Usonian projects, a term coined by Wright to describe his vision of the US landscape, is in the Puget Sound area and is being sold by Jack Cullen, the stepson of the original owner and client Ray Brandes.
Brandes and his wife Mimi wrote to Wright in 1951, asking him to design a small house for a 'simple unaffected servant-less life'.
Wright designed 50-odd Usonian houses, devising the brand in the 1930s and continuing to design them until his death in 1959.
The Usonians were not stock plans. Wright designed each one uniquely, down to the furnishings and light fixtures.
They were generally L-shaped in plan, as is the Puget Sound home, and normally constructed of concrete block and redwood.
