The Ronald Reagan Building and International Trade Center completed the development of Federal Triangle. It is the largest building constructed in Washington, DC in 50 years and the nation's second largest Federal complex. The Center's 3.1 million gross square feet include offices, trade and tourism agencies, retail shops, restaurants, theaters, and exhibition space.

Lee + Papa and Associates designed the urban plazas surrounding the complex including: relocation and redesign of the historic fountain at the 14th Street Entry and all of the surrounding streetscape and the monumental central courtyard that accommodate public events and incorporates public art.
