Historically, buildings in the Lower Rother Valley have used nature as a source of energy. The new house intends to continue this tradition, harnessing its energy from nature while creating minimal impact on the environment. Located on a sloping site, facing south, the single storey 190sqm 3-bedroom home takes advantage of the site’s resources to make the home entirely self-sufficient. At the same time by using passive design principles, a comfortable, low energy live/work environment is created.

‍

The building takes a fabric first approach, and has been designed in close collaboration with engineers from the Low Carbon Trust to minimise the building’s carbon footprint. The house is orientated facing south for passive solar gain and equipped with solar panels to harness the sun; it will be naturally ventilated with openable rooflights; it will use its thermal mass and a high level of external insulation to minimise energy use; gray water will be collected and recycled. These strategies ensure that the house will heat and cool itself without reliance on electric heat or the burning fossil fuels or wood.

The house will be built from recycled car tyres, in recognition that this waste product - millions of which end up in landfill each year - is a widely available natural resource. 1500 tyres (which equates to 13 tons of tyre waste) will be used in combination with rammed earth, excavated from the site itself. The tyres will be rendered with lime render pigmented with earth tones.  To ameliorate the incline in the slope, and reduce visual impact the house will be partially submerged into the landscape.

Food production is an integral part of the proposal, and the scheme includes an extensive timber structured glass house which runs the length of the south elevation providing 45sqm of space for the family to grow their own produce. A coloured zinc sanding seam roof will be installed to harvest rainwater to water plants and flush toilets. The wider project includes the rewilding of the former paddocks and surrounding agricultural fields to improve biodiversity and new vegetable allotments which will be farmed using permaculture principles.

It is intended that the house will be self built by the client - Anneli and Matthew Hukins - with the support and help of friends and craftspeople from the local community, as well as expert knowledge provided by engineers, consultants and members of the Low Carbon trust. Every aspect of the project has been designed with resources and longevity in mind, following circular economy principles.
