Grand Designs: Devon

Grand Designs, the show that follows Britain's most ambitious house-building projects, returns for a brand new series. Presented by designer and writer Kevin McCloud, each programme follows a different set of people who set out to pursue their vision and build their own dream house. For the last 20 years, Pat Becker has been living in a large Georgian family house overlooking the sea in Devon. Now that her family have flown the nest and the house has grown too big for her, she's decided to build a new home at the bottom of the garden. Shaped like a curvy seashell, the new house has concrete and polystyrene walls, which spiral down from the central staircase. Her architect has promised it will take only six months to build but constructing a round house is never straightforward.
