The show starts at an ancient stone circle on the Salisbury Plain, then we check progress on the site. Richard Trethewey explains the shower, pump and heating systems and introduces plumber Stan Newton. On the roof, David shows the single membrane weatherproofing system. Our master carpenter points out the features of the American custom windows, and then takes viewers to the workshop where the flat's kitchen furniture is being made.

Our master carpenter shows us the details of the new staircase leading up to the flat. Carla goes through the lighting plan for the entire flat. David Booth reviews the front wall and discusses the kitchen installation. Tiler Terry Hallow works in the master bathroom, while the guys inspect the hardwood flooring and trim and stainless steel hardware. We then visit the Thames Barrier. New steel beams are fitted in the front wall, and only a few feet away, Jeremy looks at the recently installed kitchen. Design consultant Peter Leonard walks through the flat with Carla.
