The residence tucked on two acres southwest of Camelback Road and 56th Street is one of 350 designed by famed architect Frank Lloyd Wright, who wintered in Scottsdale, but it’s one of only two that Wright designed for his children.

The 2,200-square-foot home, built in 1951 of circular concrete block, wood and metal, remains impeccably intact, due in large part to the fact that it has only had one owner. David Wright lived in the home until his death 11 years ago and his widow, Gladys, passed away this winter at 104. Designed by Wright as an example of how to live in the desert Southwest and representative in every way of Wright’s belief that form indeed follows function, a spiral ramp hugging the outside of the home leads visitors to the second level’s main living areas. Elevating the bedrooms and leisure rooms allows those areas to capture desert breezes and circulate the air throughout the home.

The interior ceilings, bookcases, cabinets, built-in seating and storage, all original, are carved out of Philippine mahogany. The concrete floor in the living room is adorned with a Frank Lloyd Wright-designed rug, inspired by Wright’s interest in Asian textiles. It’s as if a museum curator had been living here to preserve its contents. A guestbook sits on a bookshelf and the shortage of entries reflects the value the Wrights placed on privacy.

Gladys’ luggage (monogrammed with the initials “G.W.”) remains in a room off the living area. An old shaving kit sits on the vanity shelf in the bathroom. The tables and chairs are all original. The kitchen has original counters (the first prototype of Formica) and cabinets, all of which appear to be in remarkably good shape. The furniture, rugs, keepsakes, knickknacks and original blueprints all convey with the sale of the home. It’s been speculated that the buyer of the property will be a devotee of Frank Lloyd Wright and will preserve the home as an architectural art piece.

So many aspects of the home seem far ahead of their time, including the disproportionately large fireplaces, ample storage, built-ins and niches, stained concrete floors, ambient lighting, butted glass, walls of windows and a wrap-around deck. Below the living areas is a three-car carport, butcher’s-style walk-in cooler with wine storage, secluded courtyard and egg-shaped pool. The guest house, designed by Frank Lloyd Wright’s chief architect John Howe, could serve as an ideal writer’s retreat or home office.

Worthy of the buzz it has created in real estate and architecture circles, this “castle in the air” is befitting of royal treatment.
