Project overview
Designed by and for Adrian James Architects, Copper Bottom is a compact, all-electric home on the edge of Oxford’s Green Belt. Set within a wildflower meadow overlooking the city’s spires and neighbouring greenery, the project brings together sculptural form, low-carbon construction, and exceptional energy performance.
The building’s copper skin folds over a carefully engineered timber superstructure, shaping a bold, faceted geometry that responds to climate, orientation, and context. Internally, the plan is efficient and adaptable, designed to support multigenerational living while maintaining a modest footprint. Deep eaves and angled cladding shield the generous glazing from solar gain, contributing to the home’s passive performance strategy.
Beneath the shell, a palette of high-quality, durable materials reflects a fabric-first approach. Brickwork features prominently in both expression and comfort: externally, Freshfield Lane’s Danehill Yellow stocks sit low in the landscape, providing a crafted base that contrasts the copper above. Internally, Selected Dark bricks laid in white mortar offer visual depth and a tactile counterpoint to lighter timber surfaces, enhancing thermal mass and material richness throughout the day-lit interiors.
Every element of the house has been considered through the lens of carbon and longevity. Foundations are shallow to reduce concrete use; the SIP structure delivers excellent airtightness and insulation; and the cladding system combines timber trusses, plywood, and 100% recycled copper. The result is a net positive, zero-carbon building powered by 37 solar panels, a 20kWh battery, and an air source heat pump, with heat recovery reaching 90%.
Rainwater harvesting, pollinator planting, and rapid EV charging infrastructure complement the home’s broader sustainability goals. Built for minimal maintenance and maximum adaptability, Copper Bottom offers a quietly radical blueprint for future-proofed family housing.
