This is The Edge, a factory-built home inspired by Mies van der Rohe’s Farnsworth House (not to be confused with the E.D.G.E. prefab). UK-based Boutique Caravans designed and built the modern prefab – which measures 22′ x 42′ – with cold-formed steel, SIPs, and triple-glazed windows. It’s a show house in Penmayne Edge Park in Rock, North Cornwall, a community of 10 low-energy holiday homes in the UK.
The Edge has two bedrooms, two baths, a fully-integrated kitchen, multi-room audio with iPod docks, mirror televisions, zoned underfloor heating, and scheme lighting, according to Stuart Duncan of Boutique Caravans.
In terms of construction, The Edge includes a super-insulated airtight structure, a heat recovery system, rainwater recycling, and solar photovoltaics. Most of the steel structure is outside of the SIP envelope (125mm thick with polyurethane foam) to eliminate thermal bridging.
At the same time, the steel structure is extremely rigid and strong. Each vertical steel column has a removable eye to lift and place The Edge on a site with precision. Here’s a time-lapse video of the construction; Boutique Caravans ships The Edge in two halves and connects them on the site.
The Edge is built to a Level 4 of the Code for Sustainable Homes, which has a total of six levels. To save energy, the prefab has halogen and LED lighting, top-notch Bosch appliances, and an efficient Nilan heat recovery and ventilation system.
Boutique Caravans makes The Edge with two or three bedrooms in a variety of layouts. The strong exterior shell provides some design flexibility because none of the interior walls are load bearing. The Edge is built for about $225 per square foot, or ~$200 per square foot “without the fun stuff,” said Duncan.
