Built in the Usonian style, a term Wright used to distinguish contemporary American architecture from past conventions, the home is outfitted with several nods to the ideas of the late architect. Practically all of the wood detailing in the home was hand-carved by the owner, Mr. Frank, who is an avid wood worker. In the foyer, pictured here, a custom-made 'light box' fixture that Mr. Frank built hangs from the ceiling.

One of the most intricate wood carvings Mr. Frank created is in the dining room, shown here. The ceiling feature was hand carved and screened with lamp shade material to diffuse the light from fluorescent tubes within. 'All you see is diffused, beautiful, even light,' he said. He also built the 12-person dining room table and chairs.

Mr. Frank enjoys the dramatic high-backed chairs in part, he says, because they 'create a room within a room' for guests seated at the table. Despite their high-concept design, Mr. Frank says they're very comfortable. The dining room set, as well as much of the other woodworking in the home, is included in the sale, he said. Most of the wood furnishings were carved from red oak around 1985, he said.

Mr. Frank, a neurologist, expects to retire from his practice later this year. Ms. Frank is a former nurse. They met during a research program, he said. Mr. Frank credits his interest in woodworking to his father, who was a mechanical engineer. 'I caught on to doing things with my hands and have been doing it ever since,' he said. The living room, with a recessed sitting area and stone fireplace, is pictured.

The wood trim on the ceilings and walls were also created by Mr. Frank. Flooring throughout the main floor of the home is travertine marble. Natural stone plays an integral part in the home's design, both inside and out. Mr. Frank says there is 600 tons of quarried stone, mostly from Wisconsin, used throughout the property.

A home office features one of the home's fireplaces. The narrow, flat bricks used in this fireplace were a signature of Wright's design, Mr. Frank said. There is also a woodworking shop on the property, where Mr. Frank created many of the home's wood finishes.

The home measures roughly 10,000 square feet, or 12,000 square feet when including the basement, the listing agent said. The home has seven bedrooms and 8½ baths, according to the listing. One of the bedrooms is shown.

Mr. Frank says they wanted wide hallways with a lot of wall space to display their art collection.

The home includes a three-level elevator. There is also an indoor sports court for racquetball and basketball, among other things.

The lower level includes a home theater with a projection screen, as well as this 1950s diner-inspired social area. They live in the home with their daughter and two grandsons. Mr. Frank said the home is equipped with smart-home features that control the lighting and other systems.

Mr. Frank says they're reluctant to sell, but 'you got to retire sometime, and you got to downsize.' Were it up to them, 'we would be happy to be buried in the backyard,' he joked. They expect to stay in the area after the sale.

The home was listed in February with Michael Zawislak of Baird & Warner, for $2.6 million. Prior to that, in 2011, it was listed with a different broker for just under $3 million.
