Sitting on seven acres of secluded woodlands, the 1940 James B. Christie House embodies Wright’s Usonian concept, which called for simple, single-story dwellings that embrace natural materials and a strong visual connection to the outdoors. The expansive horizontal structure, built from cypress wood, brick, and glass, features an L-shape plan common to Wright’s Usonian houses. Glass walls, clerestory windows, and original built-in seating, tables, and chairs can be found throughout the home. It’s currently on the market for $1.45 million.

Wright designed the Stuart Richardson House in 1941 for an actuary and his wife following his concept of Usonian architecture. Constructed ten years later under his guidance (and meticulously restored to “purists’s standards” in 2006), the 1,800-square-foot three-bedroom features a unique hexagonal floor plan that leaves all but two of the residence’s angles measuring either 60 or 120 degrees. The brick house also boasts extensive cypress paneling and woodwork, most noticeably on the ceilings, where boards meet at chevron-like angles, drawing the eye toward various points of the house. It’s now on sale for $1.2 million.

This humble Staten Island structure was part of a line of prefabricated homes that Wright designed for builder Marshall Erdman, reflecting their shared passion for affordable, easy-to-construct housing. The Crimson Beech, as it’s known, is an L-shaped structure with four bedrooms, a sunken living room, a standard carport (as opposed to a garage, which was added in later iterations), and a gallery. It was built in 1959 and is still used as a private residence.

Wright was responsible for both the planning and the design of three of the homes within the Usonia community, located in Pleasantville, NY. Situated on 97 acres of land, the community eventually grew to have 47 homes. “One of Usonia’s main draws was the idea that you could build a beautiful home in the community for very little money—$5,000 to $7,500, according to Wright’s original estimates,” writes Amelia Schonbek in a history of the cooperative on Curbed. (Of course, those prices ballooned quickly—as Wright projects tended to do.) But the community—and its Wright-designed homes—remains to this day, and is now listed on the National Register of Historic Places.

Another Usonian home can be found on Long Island, where Wright built this seven-room house for publisher Ben Rebhuhn and his wife. Built for $35,000, the house has two bedrooms, with the second floor opening up into a huge, two-story “great room” on the ground level. The home was nearly destroyed by a fire in the 1970s, but after the fact, it was restored by Wright acolyte Morton Delson and remains a single-family residence.

The now-lost Hoffman Auto Showroom on Park Avenue wasn’t the only collaboration that Wright did with Austrian auto importer Max Hoffman. The architect also created a personal residence for Hoffman in Rye, NY, within a posh gated community. The “seashore cottage” was designed to Wright’s exacting specifications, though Hoffman was able to persuade him to make some changes; a carpet design, never used, ended up in Wright’s Taliesin compound. The L-shaped home has gotten some additions over the years, including an enclosed garage.
