After five years in the making, BIG has completed The Heights, a new public school building in Arlington, Virginia that not only offers a unique and energy-efficient take on school architecture, but also helps maximize density and open space. Located along the Rosslyn-Ballston corridor, The Heights combines two existing secondary schools into a new 180,000-square-foot building that opens like a fan with a cascade of green-roofed terraces to provide an indoor-outdoor learning landscape.
