Buehler, Maynard and Katharine, House

Why it's listed
Built in 1948-1949 at 6 Great Oak Circle in Orinda, this house was designed by Frank Lloyd Wright for engineer and inventor Maynard Buehler and his wife Katherine. It is a Usonian design, among the first of that type Wright built in California. The L-shaped plan is divided into a family area with a hexagonal living room, a bedroom wing, and a concrete block workshop at the east end. Walls are wood-clad over a steel frame, with red-colored concrete floors, a flat multi-level roof and wide eaves. The rear faces a creek and a large Japanese garden through glass walls. A 1994 fire destroyed much of the bedroom wing. Walter Olds, who had supervised the original construction as a Taliesin apprentice, oversaw the 1995-1997 rehabilitation, working from Wright's original plans. A guest house and playhouse that Olds designed in the early 1950s, along with the pool and garden features, are part of the property.
Significance in brief: The nomination presents the house as a superb example of Wright's late residential work and one of his first Usonian houses in California. It combines Wright's L-shaped "polliwog" plan with a hexagonal living room. The house was carefully rehabilitated after a 1994 fire under Walter Olds, who had supervised its original construction, which kept its integrity.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
