Maybe they built it to be a tourist attraction? Gemma is going to be in the house in the diary room for photos and autographs during the week. With the diary room upstairs, they can do that all summer. Plus people come to visit the house when the show is over.If they did that then that's what I don't get, why invest all that $$ and effort into the show then give only the bare minimum air time? It's like building a million dollar nightclub and not employing any door staff so no-one can get in.
