Martin Roberts meets a father-and-son building team working on a large semi in Derbyshire, and a mother and daughter in Belfast doing up a four-bed terrace. Lucy Alexander looks around a modest one bedroom flat in Clydebank in Scotland which is just about ready to move into.

Martin and Lucy travel up and down the country visiting properties which have sold at auction. They see two very different terraced houses in Lynemouth and Belfast and a bungalow in Derby which a couple plan to make their forever home.
