Though this 2,808-square-foot home in Lewes, East Sussex, England, used to be an old workshop, Sandy Rendel Architects transformed it into a beautiful home with a building shell that was made of SIPS (structured insulated panels), and prefabricated offsite.
The roughly 5,000-square-foot Lens House renovation, which was finished in 2012 and just won a 2014 RIBA National Award, required six years, major remedial work on the roof and walls, approval from the planning committee, and even a sign-off from a horticulturalist to guarantee the backyard excavation didn't interfere with a walnut tree. "These things aren’t for people who are in a hurry," says architect Alison Brooks. The focus is the ten-sided trapezoidal office addition. "It wraps itself around the house with a completely different set of rules than the Victorian building," she says.
