The house sits at the top of the Claverton Valley on the outskirts of Bath, and replaces a low-grade mobile home. The design is a response to the woodland setting and arranges accommodation into two distinct elements. The main volume is clad with rough-cut oak boarding and contains the entrance and kitchen on the ground floor and living room above. A second, single storey wing is faced with oxidised steel panels and contains sleeping areas that open directly into the garden. The grass roof of the bedroom wing provides a terrace to the adjacent first floor space. The house employs experimental construction and technology, incorporating rainwater harvesting, passive and active solar energy, and is virtually free from pvc materials.
