The iconic American fashion brand owns six private labels sold in more than 90 countries. In the late 1990s, Gap realized that they needed to unite their disparate leadership and development teams under one roof. They engaged Robert A.M. Stern, Dean of the Yale School of Architecture, to conceive a new headquarters. His 15-story, 540,000 square foot design included a cafeteria, an art gallery, two levels of underground parking, outdoor decks, an exhibition hall, and a rooftop garden.
