If you like the idea of going eco-friendly for a while but don't want to completely give up on comforts, this cosy barn powered by renewable energy could just be a happy compromise. The renovated cob and stone property sits within six acres of idyllic riverside woodland and is built out of natural materials, including oak, lime, cob, pigmented clay plaster and locally sourced slate. Inside, there are a few rustic features, such as the exposed stonework and wood-burning fireplace, but otherwise, it's undeniably contemporary thanks to the conservatory, sleek kitchen and pristine bathrooms. The fact that it's powered by a wind turbine and a heat pump is pretty impressive, too. Given the peace and tranquillity of the surrounding grounds, you'll be happy to hear that there's a natural swimming pool close to the home — shared only with the host, who lives on the site, and one other barn — as well as a barbecue and some spots for an alfresco feast. Although it feels like you're in splendid isolation at this address, you can head back to civilisation pretty swiftly if you wish. The town of Truro takes a quarter of an hour to reach in the car, while Perranporth Beach on the north and south Cornish coastlines can be reached in just under twenty-five.
