Three teams of builders go head to head, pricing up jobs and offering designs, and the homeowners choose which team to go with. The first job on offer is for homeowners Sarah and John in Farnworth near Bolton. They desperately want to update their 70s bathroom on a budget of £3,000. The builders offer up three very different designs. Tracy and Vic embrace the 70s vibe, offering a watermelon colour scheme and wood panelling, Alex and Chris suggest uPVC ceiling cladding to help condensation, and Mark and Chris come up with a practical hydraulic sink to help John, who has a form of dwarfism. But who will Sarah and John go for? Meanwhile, in Cobham, Surrey, Rebecca wants smart storage solutions for her under-stairs cupboard. The builders come with three different designs, but of course only one pair can win the job.
