Ronald Reagan Building and International Trade Cen

Ronald Reagan Building and International Trade Center

Occupying the last open site on Pennsylvania Avenue, the Reagan Building was designed to complete and augment the 70-acre wedge of government offices known as Federal Triangle.


At 3.7 million square feet, it is the largest federal building after the Pentagon, fulfilling an extraordinary rich mixed-use program of government offices, private businesses and public amenities while creating significant public spaces. In the seemingly impenetrable wall of government buildings that separates downtown from ceremonial Washington, the Reagan Building emphasizes access and permeability.
