The Copper Bottom House, designed by architect Adrian James, is a remarkable example of sustainable architecture and a home powered by renewable energy. Built for James and his family, this two-story residence is located on the slopes of Harcourt Hill in Oxford. Its green-patinated copper shell functions as a “habitable power station,” while the roof is covered with solar panels. The thoughtful design not only shields the house from harsh summer sunlight but also allows low winter sun rays to enter, enhancing comfort and energy efficiency throughout the year.
The ground floor of the Copper Bottom House features a double-height gallery space that serves as the heart of the home. Adjacent to it is an open-plan living and kitchen area, with a mezzanine level designed as a home office. The upper floor includes four bedrooms, one of which has a private ensuite bathroom. One of the most distinctive features of the house is its unique origami-inspired copper shell, with an angular roof specifically designed to shield the interior from excessive heat.
Through smart design, the house creates angled side volumes that accommodate east- and west-facing windows, aiding in natural ventilation. At the top of the house, two angular, ear-like structures are designed to draw in cool night air and expel built-up heat during the day. This dynamic and distinctive architectural form contributes to a meaningful living experience, infusing the space with a sense of energy and positivity for its residents.
Copper Bottom House is equipped with 37 photovoltaic panels, allowing it to generate more energy than it consumes, effectively making it a zero-carbon home. The project not only minimizes operational energy use but also offsets the embodied energy from its construction. The interior features white walls and minimalist details, creating a bright and open atmosphere. Combined with oak furnishings and large windows, the space offers stunning views of the surrounding landscape and the spires of Oxford.
