Phillips Family Athletic Center continues Greenhill's commitment to excellence in academic and athletic standards. The commitment is exemplified in a 50,000 square foot addition comprised of a 25-meter natatorium and a 1200-seat competition gymnasium appended to two sides of a renovation field house. The gymnasium is stacked on top of an entire level of support space. A bow-shaped roof crowns the gymnasium volume with extended sunscreens running the length of each side. These shading devices, in turn, are supported by diagonal steel struts springing form the top of the buttress columns.
