CaSA Architects has achieved NPPF 55 status for the development of a new house in a listed parkland near Frome, Somerset. NPPF 55, recognised as one of the most difficult planning applications to achieve, sets strict planning restrictions to allow only truly outstanding or innovative architecture of the very highest quality and standard to be built in the English countryside. The house is proposed as an exceptionally high standard sustainable building with a minimal environmental footprint both in construction and in use. CaSA Architects design includes: • a fabric-first approach to deliver a highly insulated and airtight construction to achieve the exacting German Passivhaus standard • using natural, unprocessed materials as much as possible • careful orientation of the building to optimise passive solar gain and minimise heat loss through the glazing • on-site energy generation with photo voltaic panels. The South West Design Review Panel guidance letter in support of the design observed “We welcome the house as a demonstration that good, strong, contemporary architecture can sit harmoniously in a rural setting close to heritage assets.” The project is expected to go to site in the autumn of 2016.
