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.

The design’s pronounced diagonal geometry is a direct response to Pennsylvania Avenue, which bends east toward the Capitol. The building meets the avenue at 90 degrees and hinges back from a corner rotunda to symbolically turn the street into the site.
Circulation systems are choreographed to move people through a sequential unfolding of clearly organized layers of space. Visitors are invited to enter a large outdoor plaza and to proceed inside to a skylit conical space and public concourse offering retail, dining, and vital connections to mass transit and neighboring buildings.
