Edgar J. Kaufmann in the context of Palm Springs, California

Fallingwater is a house museum in Stewart Township in the Laurel Highlands of southwestern Pennsylvania, United States. Designed by the architect Frank Lloyd Wright, it is built partly over a waterfall on the Bear Run stream. The three-story residence was developed as a weekend retreat for Liliane and Edgar J. Kaufmann Sr., the owner of Kaufmann's Department Store in Pittsburgh. The Western Pennsylvania Conservancy (WPC), which has operated Fallingwater as a tourist attraction since 1963, maintains 5,000 acres (2,000 ha) surrounding the house.

Edgar Kaufmann Sr. had established a summer retreat at Bear Run for his employees by 1916. When employees stopped using the retreat, the Kaufmanns bought the site in July 1933 and hired Wright to design the house in 1934. Several structural issues arose during the house's construction, including cracked concrete and sagging terraces. The Kaufmanns began using the house in 1937 and hired Wright to design a guest wing, which was finished in 1939. Edgar Kaufmann Jr., the Kaufmanns' son, continued to use the house after his parents' deaths. After the WPC took over, it began hosting tours of the house in July 1964 and built a visitor center in 1979. The house was renovated in the late 1990s and early 2000s to remedy severe structural defects, including sagging terraces and poor drainage.

Broadacre City was an urban or suburban development concept proposed by Frank Lloyd Wright throughout most of his lifetime. He presented the idea in his book The Disappearing City in 1932. A few years later he unveiled a very detailed twelve-by-twelve-foot (3.7 × 3.7 m) scale model representing a hypothetical four-square-mile (10 km) community. The model was crafted by the student interns who worked for him at Taliesin, and financed byEdgar Kaufmann. It was initially displayed at an Industrial Arts Exposition in the Forum at the Rockefeller Center starting on April 15, 1935. After the New York exposition, Kaufmann arranged to have the model displayed in Pittsburgh at an exposition titled "New Homes for Old", sponsored by the Federal Housing Administration. The exposition opened on June 18 on the 11th floor of Kaufmann's store. The model is now on display at the Museum of Modern Art. Wright went on to refine the concept in later books and in articles until his death in 1959.

Kaufmann's was a department store that originated in Pittsburgh, Pennsylvania.

The store was owned in the early 20th century by Edgar J. Kaufmann, patron of the famous Fallingwater house. In the post-war years, the store became a regional chain in the eastern United States, and was last owned by Federated Department Stores. At the height of its existence, it had some 59 stores in 5 states. Formerly part of May Department Stores prior to that company's acquisition by Federated on August 30, 2005, Kaufmann's operated as part of the Filene's organization in Boston, Massachusetts. On February 1, 2006, the Filene's/Kaufmann's organization was dissolved and the management of its stores was assumed by Macy's East and the new Macy's Midwest. On September 9, 2006, Macy's retired the Kaufmann's name as Federated Department Stores converted the former May Company brands to its masthead. In 2015, Macy's closed and sold the iconic Pittsburgh store for redevelopment as part of the company's ongoing reorganization of its owned properties. Core Realty of Philadelphia, the new owners of the building, have named the proposed mixed-use property "Kaufmann's Grand on Fifth" in honor of the historic property.

The Point Park Civic Center was a proposed civic center for downtown Pittsburgh, Pennsylvania, United States, where the confluence of the Allegheny and Monongahela Rivers forms the Ohio River. Frank Lloyd Wright designed the structure on a commission from Edgar J. Kaufmann in the late 1940s. Wright initially envisioned a circular building more than 1,000 feet (300 m) in diameter and 175 feet (53 m) tall. The structure, containing an opera house, sports arena, three movie theaters, and a convention hall, was wrapped by a spiraling strip of road. The plan expressed Wright's insistence on bringing the automobile into the social setting. It did not find favor with Pittsburgh authorities.

To make the design more palatable to its audience, Wright developed a radically different proposal for a monolithic tower supporting bridges across the Allegheny and Monongahela. This too was unsuccessful, and none of Wright's work for the site was ever built. The site is now occupied by Point State Park. Elements of Wright's plan contain similarities to other Wright designs, including the Solomon R. Guggenheim Museum and his unrealized plans for Monona Terrace.
