This almost falls under the "Nice House, shame about the series" category. Although a quite basic functional design the house as a whole works well and I don't mind it not getting a new layout just for the sake of it.
The one change though they have made this year is to the Eviction Room. It looks so much better with the nominees sat in proper chairs, rather than bunched up on a sofa, and the other housemates on the long couch opposite them. It's set up so much better than it was last year and is nicely designed too. It feels more like an eviction set rather than just another room.
