Originally built for the State, War, and Navy Departments between 1871 and 1888, the Eisenhower Executive Office Building now houses a majority of offices for White House staff.
The Eisenhower Executive Office Building, located next to the West Wing, is an impressive structure that commands a unique position in both our nation’s history and its architectural heritage.
Designed by Supervising Architect of the Treasury Alfred Mullett, the granite, slate, and cast iron exterior makes the EEOB one of America’s best examples of the French Second Empire style of architecture. It took 17 years for Mullett’s masterpiece to finally be completed.
History
Next door to the White House, the Eisenhower Executive Office Building (EEOB) commands a unique position in both our national history and architectural heritage. Designed by Supervising Architect of the Treasury, Alfred B. Mullett, it was built from 1871 to 1888 to house the growing staffs of the State, War, and Navy Departments, and is considered one of the best examples of French Second Empire architecture in the country. In bold contrast to many of the somber classical revival buildings in Washington, the EEOB’s flamboyant style epitomizes the optimism and exuberance of the post–Civil War period.
