Significant later works

Fallingwater, one of Wright's most famous private residences (completed 1937), was built for Mr. and Mrs. Edgar J. Kaufmann, Sr., at Mill Run, Pennsylvania. Constructed over a 30-foot waterfall, it was designed according to Wright's desire to place the occupants close to the natural surroundings. The house was intended to be more of a family getaway, rather than a live-in home. The construction is a series of cantilevered balconies and terraces, using limestone for all verticals and concrete for the horizontals. The house cost $155,000 (equivalent to $3,285,000 in 2023), including the architect's fee of $8,000 (equivalent to $170,000 in 2023). It was one of Wright's most expensive pieces. Kaufmann's own engineers argued that the design was not sound. They were overruled by Wright, but the contractor secretly added extra steel to the horizontal concrete elements. In 1994, Robert Silman and Associates examined the building and developed a plan to restore the structure. In the late 1990s, steel supports were added under the lowest cantilever until a detailed structural analysis could be done. In March 2002, post-tensioning of the lowest terrace was completed.

Taliesin West, Wright's winter home and studio complex in Scottsdale, Arizona, was a laboratory for Wright from 1937 to his death in 1959. It is now the home of the Frank Lloyd Wright Foundation.

The design and construction of the Solomon R. Guggenheim Museum in New York City occupied Wright from 1943 until 1959 and is probably his most recognized masterpiece. The building's unique central geometry allows visitors to experience Guggenheim's collection of nonobjective geometric paintings by taking an elevator to the top level and then viewing artworks by walking down the slowly descending, central spiral ramp.

The only realized skyscraper designed by Wright is the Price Tower, a 19-story tower in Bartlesville, Oklahoma. It is also one of the two existing vertically oriented Wright structures (the other is the S.C. Johnson Wax Research Tower in Racine, Wisconsin). The Price Tower was commissioned by Harold C. Price of the H. C. Price Company, a local oil pipeline and chemical firm. On March 29, 2007, Price Tower was designated a National Historic Landmark by the United States Department of the Interior, one of only 20 such properties in Oklahoma.

Monona Terrace, originally designed in 1937 as municipal offices for Madison, Wisconsin, was completed in 1997 on the original site, using a variation of Wright's final design for the exterior, with the interior design altered by its new purpose as a convention center. The "as-built" design was carried out by Wright's apprentice Tony Puttnam. Monona Terrace was accompanied by controversy until the structure was completed.

Florida Southern College, located in Lakeland, Florida, constructed 12 (out of 18 planned) Frank Lloyd Wright buildings between 1941 and 1958 as part of the Child of the Sun project. It is the world's largest single-site collection of Frank Lloyd Wright architecture.
