This episode looks at listed buildings. Is it possible to extend and adapt listed buildings or are they simply a historic headache? A very determined couple attempt to turn a Grade 2 star listed building into a beautiful family home. The Crown House in Hastings is an abandoned pub, but if Pete and Janine Rich can get permission for change of use, from commercial to residential, they will take the first step in a quite remarkable transformation. The projected spend is high, but the potential rewards are even higher. Joel Griggs has sunk all his savings into a most unusual project: he wants to create a crime museum in Hastings. Joel's museum will be located in caves behind a Grade 2 listed facade. He is confident he can make the business a success - but only if he gets planning permission to erect a large sign on the front of his listed building. If all goes to plan, Joel will be turning over an astonishing £80,000 per annum.
