The extension has a flat roof with a three-layer bitumen insulated system, and double-glazed aluminium windows and doors to help with draft concerns. This building adopted low U-values with a high air tightness to reduce the energy demands and associated CO2 emissions. New openings were created to form new doorways and window fenestrations. Natural lighting was a priority for the Academy, therefore rooflights were included within the design to allow the highest level of daylight possible to enter the space. Green WindyPods were installed around the windows to match the school colours.
This extension connects to the original school building which dates back to 1912. Special consideration was taken with construction detailing to make sure connection points would be long lasting, waterproof, and in accordance with Building Control. Scale is minimised by accommodating areas at ground floor level, reducing the impact on the surrounding school.
