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.

But the landscape was beautiful and they both felt they belonged there

A derelict woollen mill in a Yorkshire village may not say 'modernist' to everyone. But Chris and Gill - who, fortunately, run their own specialist joinery business - saw it as the perfect opportunity to create a visionary home. They liked the traditional brick of the building and opted to keep the exterior virtually untouched. Inside, they would strip everything out and make a home of fluid spaces, based around an open-plan ground floor, an atrium and a galleried upper floor.
