Double Your House for Half the Money

Sarah meets Candida Gubbins who wants to dig beneath her London flat to create a new floor. Basement extensions are always tricky, but for Candida, project managing her first build and using an inheritance from her mother means she's in for sleepless nights. In Wolverhampton, Jay and Stephen want to bring Kardashian style to their extension. Although estate agents, the couple have never done a building project and at times their eyes are bigger than their wallets. A new baby, a tight timescale plus a daily battle to keep the building site from invading their tiny living space - as well as trying to do a lot of the work themselves to keep within budget - means Sarah is worried whether they will manage to finish on time... if at all.
