L'Enfant Plaza is a complex of four commercial buildings grouped around a large plaza in the Southwest section of Washington, D.C., United States. Immediately below the plaza and the buildings is La Promenade shopping mall.The plaza is located south of Independence Avenue SW between 12th and 9th Streets SW (9th Street actually runs underneath the centers of the buildings on the easternmost side of the plaza). It was built perpendicular to L'Enfant Promenade, a north-south running street and pedestrian esplanade part of which is directly above 10th Street SW. The plaza is named for Pierre (Peter) Charles L'Enfant, the architect and planner who first designed a street layout for the capital city (see L'Enfant Plan). It was dedicated in 1968 after completion of the north and south buildings.

The Hilton Washington DC National Mall The Wharf, previously known as the L'Enfant Plaza Hotel, is a 367-room hotel located on the top four floors of a 12-story mixed-use building in downtown Washington, D.C., in the United States. It was designed by architect Vlastimil Koubek, and was opened on May 31, 1973, as the Loews L'Enfant Plaza Hotel, named after Pierre Charles L'Enfant, the first surveyor and designer of the street layout of the city. The hotel sits atop L'Enfant Plaza, an esplanade and plaza structure erected above a highway and a parking garage in the Southwest quadrant of the District of Columbia. The plaza and hotel were approved in 1955, but construction did not begin on the plaza (on which the hotel sits) until 1965. The plaza and esplanade were completed in 1968. The start of construction on the hotel was delayed three years, and was completed in May 1973. The construction led to a lawsuit after it was found that the foundation of an adjoining structure had encroached on the hotel's property. The hotel suffered a serious fire in 1975 that claimed the lives of two people. L'Enfant Plaza Corp., which owned the hotel, sold the structure to Sarakreek Holdings in 1998, which in turn sold it to the JBG Companies in 2003. A legal battle ensued over the hotel's ownership. The hotel's original operator, Loews Hotels, was replaced after thirty-two years by Crestline Hotels & Resorts in 2005, which was in turn replaced by the Davidson Hotel Company in 2010. The hotel closed on December 3, 2013, for what was originally intended to be a year-long overhaul and upgrade of the entire property. It reopened on April 1, 2019, as the Hilton Washington DC National Mall.

The Inner Loop was two planned freeways around downtown Washington, D.C. The innermost loop would have formed an oval centered on the White House, with a central freeway connecting the southern segment to the northern segment and then continuing on to Interstate 95. Interstate 95 would have met Interstate 66, Interstate 295, Interstate 695, and US 50 while traversing the Inner Loop. A second loop was an arc across the northern section of the city, beginning at East Capitol Street at the Anacostia River and using the Missouri Avenue NW and Nebraska Avenue NW commercial corridors to terminate in Georgetown.

Tiber Island also known as The Island was a man-made island in Washington, D.C. formed when the Washington City Canal was dug to connect the stream beds of Tiber Creek and James Creek, creating an island out of an existing peninsula southwest of the Capitol. The canals have since been filled in, rejoining the island to the mainland. The Southwest Waterfront, Buzzard Point, National Mall, and L'Enfant Plaza areas were once on the island; at that time, their isolation from "the mainland" led to the area's colloquial nickname as "The Island."The Tiber Island Cooperative Homes derive their name from the historic island.

The United States Department of Housing and Urban Development (HUD) is one of the executive departments of the U.S. federal government. It administers federal housing and urban development laws. It is headed by the Secretary of Housing and Urban Development, who reports directly to the President of the United States and is a member of the president's Cabinet.

Johnson, to develop and execute policies on housing and metropolises.

The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative.The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served in the position since February 2021. The department's headquarters are in southwestern Washington, D.C., in the James V.

The Office of Intelligence and Counterintelligence (OICI), also abbreviated IN, DOE-IN, DOE/IN, I&CI, or OIC, was established in 2006 by the merger of pre-existing Energy Department intelligence and security organizations. It is an office of the United States Department of Energy (DOE) responsible for all intelligence and counterintelligence activities throughout the DOE complex; due to this central role, OICI is designated DOE's Headquarters Intelligence. As a component of the United States Intelligence Community in addition to the Department of Energy, OICI reports to both the Director of National Intelligence and Secretary of Energy.

The Robert C. Weaver Federal Building is a 10-story office building in Washington, D.C., United States. Owned by the U.S. federal government, it was built by the General Services Administration as the headquarters of the United States Department of Housing and Urban Development (HUD). It was completed in 1968 and designed by Marcel Breuer in the Brutalist style. The building is one of two that Breuer designed for the U.S. federal government in the District of Columbia, along with the Hubert H. Humphrey Building, and is listed on the National Register of Historic Places. The building was first conceived in 1962, when President John F. Kennedy established the Ad Hoc Committee on Federal Office Space. Work began after Kennedy's successor Lyndon B. Johnson signed the Housing and Urban Development Act of 1965. A cornerstone-laying ceremony took place in November 1966, and the building was formally dedicated on September 21, 1968. The plaza was redesigned in the 1990s by Martha Schwartz. The structure was renamed for Dr. Robert C. Weaver, the first Secretary of Housing and Urban Development and the first African American Cabinet member, in 2000. After HUD announced plans to move out of the building in 2025, the federal government considered demolishing it. The Weaver Building has a curvilinear precast concrete facade, similar to Breuer's previous UNESCO Headquarters and IBM La Gaude. It is shaped like two back-to-back "Y"s, with four curving wings extending off an elongated core. Breuer designed a 6-acre (2.4 ha) plaza, which serves as the roof for an underground parking garage. The facade contains concrete panels with deeply recessed rectangular windows; the ground floor is recessed behind concrete pilotis. As built, there were two basements, a ground-level lobby and communal area, and nine office floors above. Although the building's design received architectural praise when it was built, its Brutalist style and the unoriginality of its design have also received negative commentary, especially from several HUD secretaries.
