Since the completion of the 333,620 SF Central York High School in 2005, the District has experienced unprecedented growth and requires an addition of 52,344 SF to provide more classroom space.  The additions were designed to continue to support an Academy structure and embrace the same sustainable approach as the existing building, which includes the utilization of a ground source heat pump heating and cooling system, daylighting strategies involving light and occupancy sensors, and low emitting and sustainable materials.  The District elected to, at the same time, add a 23,503 SF natatorium that includes an 8-lane competition class pool with movable bulkhead as well as supporting amenities to allow for accommodating District swim and diving meets. The existing Central York High School was completed by principals of SGA while employed by another firm.
