I predict the blue container bathroom to have gone/moved. This will make more room for a shower that can be enclosed to void any chance of getting camera shots of them in the nude, a door to be added somewhere to a mini gym, the Kitchen to have changed colour, and the bedroom will be made slightly smaller, (to make room for the gym, and as there will be less housemates. ALL beds will be single and will have bedside cabinets. Also, the front room (we already know) has been moved to where the dining room was, and there will be the hot tub where the lounge door was in the BB10 house. I also expect the pictures on the diary room doors to be changed to something fire-ey.

I also think Shirley Jones will put the screen back onto the side of the house, so the top of it is inline with the roof, and I think that the front door to the house will be changed to a CBB5 style, where it was all black, and was quite a bit bigger, and also had a yellow frame around it.
