Private house in a conservation area, overlooking the River Severn made from local oak and glass and a wall of red earth
The house is made from local oak and glass abutting an unusual wall of red earth. Against this encircling wall and buffer spaces to the north, a south-facing open-plan layout opens out to a terrace and a grass meadow with distant views beyond. The vertical volumes of chimney stack and principal bathroom are finished in render using sand from the site itself.
Low environmental impact materials and construction are used throughout, including recycled cellulose, timber, and the site earth. Energy conservation measures include solar panels, rainwater reclamation and a passive solar strategy with vines giving seasonal shading.
