George Clarke revisits Gareth Williams, who had sought his assistance four years previously as he tried to create a new home for his family by restoring a derelict Victorian church in Pembrokeshire. In order to save money, Gareth planned to carry out all the necessary work himself, but the church's location in a working graveyard gave him a host of administrative problems in addition to the difficulty of the physical labour. The last in the current dalliance with Grayson Perry comes to an end today, with the last episode airing at 10.00pm tonight.
