Design of a sustainable, carbon neutral pavilion for a park in Brent Cross which contains cafe, sport and community facilities. Our concept is inspired by the traditional park Bandstand, a common park architectural form that has stood the test of time due to its simplicity, flexibility, and adaptability. Our design takes this archetype and updates it to meet the challenges of the climate emergency, creating a new pavilion for Clitterhouse Playing Fields. A key feature of our proposal is a large outdoor decking area which will be an open, informal, flexible space for the entire community to meet and gather at any time, whether that be to meet the team before a big match, play a quiet game of chess, take a yoga class or go for a jog. The deck is broken up with a series of green courtyards to create a variety of spaces at different scales for different groups to meet. The deck is sheltered from the sun and rain by a lightweight timber canopy which is also used to harvest sunlight and rain to be used within the building. Spaces within the building that require strict thermal control such as the café and sport facilities will be formed using rammed earth walls with cork insulation and heated with ground source heat pumps to achieve PassivHaus standards. The earth for the walls will be taken from the construction site and waste rubble will be used to form gabion cage foundations.
