In the mood for architectural inspiration? Look no further. Following on from the success of the first series, in which the Royal Institute of British Architects chose Britain’s best new home, with the Grand Designs team tagging along, the show returns for a second series tonight. Kevin McCloud, Damion Burrows and Zac Monro explore some of Britain's most innovative homes, which are, as with last year, in competition for a prestigious prize. In this episode, Kevin profiles five country homes including a house camouflaged within a hill and a slice of spectacular California modernism in Cornwall.
