London-based forresterarchitects completed a home that’s so airtight it could be heated with a hairdryer. Constructed in Britain’s largest protected wetland at Norfolk Broads, the new-build Pond House is a stunning larch-clad dwelling built to passivhaus standards. While energy efficiency is a major guiding principle for the solar-powered home, the Pond House was also designed as an environmentally responsive solution that respects the surrounding sensitive landscape.
Inspired by the local vernacular, the 110-square-meter Pond House comprises a cluster of interconnected timber structures carefully angled to optimize passive solar conditions. Rough-sawn untreated Siberian larch clads all of the structures, including the roof, which also features fully integrated solar thermal and photovoltaic panels. The house derives its name from the small pond that forms the focal point of the rear garden. Rainwater is collected, treated, and reused as irrigation or is slowly released back into the ground.
The Passivhaus Planning Package guided the development of Pond House. As a result, heating and cooling costs have been dramatically reduced and the house enjoys comfortable indoor temperatures year-round. Since Pond House is wrapped in a highly efficient and airtight thermal envelope, heating requirements have been reduced so much that a traditional heating system is no longer necessary. Strategically placed windows allow for passive solar heating.
