Grand Designs - Season 14 Episode 6 Norfolk: Periscope House

Natasha Cargill wants to build a home shaped like two enormous periscopes in rural Norfolk. But a limited budget and tight planning restrictions start to take their toll. To get planning permission for her build, Natasha Cargill has to ensure not only that the materials used are sustainable, but also agree to measure the amount of diesel used to deliver them. The planning controls are so rigid in fact that even details like the type of portaloos the builders use and the size of her bath have to be monitored. Natasha has just pounds 330k to spend on construction and just six months to complete.
