This 3-bedroom home replaces an old bungalow which previously occupied the site. The new dwelling is built to Passivhaus standards of air-tightness and insulation, making the building very affordable to heat and very low-carbon. It also includes a green sedum roof to encourage biodiversity and mitigate rainwater run-off. The house features timber cladding and slate roof tiles. This palette of natural materials keeps embodied emissions low and respects the local vernacular of the village setting.
