Philip and Sue completed the construction of this house in 2019, in the grounds of their old house. The house was a self-build but owing to the complexity of the build a project manager was used.
The house is a timber framed structure constructed on site, with Celotex insulation and Firmacell internal lining. The outside has Western Red cedar cladding, with local stone on the road side. The zinc roof harvests rain which is stored in a 5000 litre tank for irrigating the garden. Photovoltaic panels provide 4.5kW of electricity, and an Air Source Heat Pump provides the domestic hot water as well as the underfloor heating. There is a ventilation/heat retrieval system (MVHR system).
An Everhot range provides a more efficient and controllable stove than a conventional Aga. Two woodburning stoves will provide extra heating in the winter. There is some doubt as to whether the underfloor heating will be used very much.
As the house is new, they have not yet collected data about the energy saved in this efficient new home but it is likely to be substantially lower than similar houses of the same size.
