A couple of weeks ago, the Cupertino City Council approved the long-awaited, 3.2-million-square-foot Apple Campus 2. Approval means that the building, notable for its purely circular footprint, is to arise on an open field north of Interstate 280, with completion expected in about two years. Designed by architectural luminary Sir Norman Foster, the main office building is notable for a purely circular footprint. Both Apple and the architect suggest that the horizontally oriented, four-story building will be gentler on Gaia than a tall building.
