You name it, this house has it: an air-source heat pump, a rainwater harvester, central-vacuuming system, triple-glazing and motion-sensitive lighting system. It also features underfloor heating and self-closing loos. The five bedrooms are arranged over three storeys.
Riefa boards are a new type of green roof substrate. They are a hi-tech fibre board made from organically grown and sustainable natural resources, including rye flour and tree bark. There are some other ingredients in there too, but forgive me if, for reasons of commercial confidence, I don’t expand on them here. But rest assured they are innovative and do what the designer intends. http://www.riefagreenroof.co.uk
