tbh the house barely changing is probably more do with the financial crises than ratings or being on 5 anything else. It can't be a coincidence that the house has barely changed since 2009 when money problems were getting worse everywhere. (BB11 is an exception because as C4's last series they obviously put a bit of effort into the design) Overall its probably one of the things that faced cuts as to most people the house doesn't really matter.
