You may have seen this one before, but its a good un. When interior designer Kathryn Tyler decided she wanted her first home, she was determined to use her skills to design and build the house herself. Her original plans, to erect a house on a tight hillside plot in her parents' back garden in Falmouth, were put on hold when her father died. Now, Kathryn has revived her concept, designing a Scandinavian-inspired eco house to fit this limiting plot. Although it's built from quite conventional materials, the house is far from normal. With a white-painted brick ground floor, and a lightweight timber frame first floor, this cubist shell gives the interior designer a chance to show off her flair inside, with cleverly designed zones and beautifully displayed vintage Danish furniture. But surely it can't all be plain sailing for someone as young and inexperienced as Kathryn?
