Kevin McCloud follows more couples building their own homes in Graven Hill, Oxfordshire. Vineet and Simmi have engaged a friend from the community to construct their new home, blurring the line between friendship and business - and things become even trickier when Vineet changes his mind about the layout mid-project. Prabhjot and Shalini's new-build is a super-quick kit house which should go up in a matter of weeks. But with such a close community, their home will need to take their friends' tastes into account as well as their own.
