Blair House, also known as The President's Guest House, is an official residence in Washington, D.C., the capital of the United States. The President's Guest House has been called "the world's most exclusive hotel" because it is primarily used as a state guest house to host visiting dignitaries and other guests of the president. Parts of the historic complex have been used for an official residence since the 1940s. Located just across Pennsylvania Avenue from the White House, it is a complex of four formerly separate homes—Blair House, Lee House, Peter Parker House, and 704 Jackson Place.

Blair House is one of several residences owned by the United States government for use by the president and vice president of the United States; other such residences include the White House, Camp David, One Observatory Circle, the Presidential Townhouse, and Trowbridge House. President Harry S. Truman and his family lived in the original Blair House from 1948 to 1952 during the White House Reconstruction. Truman survived a 1950 assassination attempt there.

Bednar of the University of Virginia School of Architecture, "Four taller office buildings dating to earlier in the 20th century were demolished and replaced with next rowhouse office builds. One has an open base to serve as an entry to the New Executive Office Building via courtyard. The historic structures were preserved and rehabilitated for smaller federal agencies. The New Executive Office Building has an offset H-shaped plan with a long brick facade along 17th Street."The building was designed by architect John Carl Warnecke, who also designed 722 Jackson Place and the National Courts Building (717 Madison Place) on the opposite side of Lafayette Park during the same period. Warnecke sought to "harmonize [the structures] with Lafayette Square's historic character and retained the domestic facades but joined the separate interiors."According to Shelley Lynne Tomkin in Inside OMB, most Office of Management and Budget civil service employees work in the NEOB, while most OMB political appointees work across the street in the EEOB.
