It's a family affair as a mother and son develop a house in Knutton in Staffordshire, a father and son work on a one-bedroom flat in London's Cricklewood and a husband-and-wife team take on an ambitious project to make a stonework shop and a brick single-storey former shop one home in Belper in Derbyshire. Martin Roberts and Dion Dublin follow the progress made on their auction buys.

A smart one-bedroom flat in Whitefield in Greater Manchester, a large bungalow bought for an unexpected use in Tipton in Derbyshire and a lovely two-bedroom flat in a Victorian building in London's New Cross are sold under the hammer. Martin Roberts, Dion Dublin and Martel Maxwell talk to the property developers who hope to make a profit from their auction buys.
