America Online converted the British Aerospace high-bay warehouse on its recently acquired campus into offices to accommodate rapid growth. Design challenges included fast-track construction, increasing square footage and introducing daylight and windows within a rigid concrete structure. By inserting a second floor, the usable area increased from 120,000 to 183,000 square feet. New glass-and-metal cladding and roof monitors allow for increased light and views. The building houses 740 employees, provides computer and conference rooms, a company store and food-service facilities. Its dynamic design embodies the AOL culture in its responsiveness to changing work areas and technologies.
