Sydenham Hill, London

Kevin meets south London chef Corinne, who loves to entertain and is rustling up plans for a beautifully crafted, double-kitchen home designed around her love of cooking. The end-of-terrace plot is on a hill and surrounded by woodland within a strict conservation area, so it won't be an easy build. But having come through a divorce and cancer treatment, Corinne sees the house as vital on so many levels, not least as an opportunity to create a space that represents her new lease of life.
