Sue and Martin took a holistic approach when they converted a pair of Devon barns into a family home. They believed that the house should look like a natural part of the landscape. So they built it using environmentally sustainable techniques and allowed much of its design to evolve during the build. The oldest barn, dating from the 1600s, was built from stone and cob - a straw-and-mud mixture characteristic of Devon - while the newer, 19th-century barn was totally of stone. The older barn would have a thatched roof, the newer barn slates. A south-facing sitting room would overlook a double-height glass atrium, which would become an indoor garden, filled with citrus trees. Four bedrooms and a study would go upstairs.
