The proposed building is located to the south of the running track, as a key component of a wider new events area flanked by existing Harriers’ buildings. From its elevated position the building overlooks the new playground, woodlands and lake. It offers community/learning space, a bistro, and public convenience facilities for all park users. The building form follows passive design principles, harnessing sunlight in winter whilst preventing overheating in summer. Bio-based materials such as timber (for structure, insulation, and roof shingles), hemp (insulation and facing blocks) and clay (boarding and plaster) were specified. The foundations will be made of crushed stone, whilst the use of cement has been avoided as much as possible. Embodied and operational carbon of the building have been carefully considered to achieve a low carbon build.
