Why it is special A striking, L-shaped design which maximises exposure to the sun. The layout, including doorways, can have many variations. All living spaces face south. How it is built Timber-frame and clay bricks, using non-sulphur plaster. Solar-panel roof can be updated with technology. Eco features Large windows maximise heat gain, while external shutters avoid heat loss and avoid overheating. Other features include an internal heat-exchange system to minimise heat loss; rainwater and greywater recycling; green roofs to retain rainwater; photovoltaic panels; organic insulation (such as sheep’s wool). |
