Hayley and Alan are not your typical restoration heroes. Struggling to find a decent sized family home, they decided to put in a bid for a Victorian chapel in the Welsh valleys. It was derelict and in need of a saviour - they bought the lot for just £25,000. With only £20,000 of their own money left to restore it, they begin a struggle of almost impossible scale. They start in the vestry to the rear, which they hope to transform into a spacious three double bedroom modern home. The plan was to then get a mortgage to complete the whole chapel, but the enormity of the task and the consequence of their tiny budget soon hits home. Simply digging foundations is a gruelling task as, rather than hiring a digger, they opt for doing it by hand to save their tiny budget. As Alun and Hayley struggle to save the centre-piece to the village, the historical investigation gains pace.
