nah itll take longer than that to get the HWH outta there, and the blue will be going and a "new" bedroom with proper beds will be coming in.
if you look closely at the HWH lounge, the floor is raised and the ceiling is dropped to accommodate the bars so those will be going as well, the extra diary room will be taken out and the room will open up to the extension (why theres been no camera angles from the far side of the HWH bedroom id say) itll look like a lot of works been done but not really (theyre clever like that) for example look at the HWH lounge, see all the blue and corrugated iron walls, looks like panels connected by the wood? exactly what it is, it'll just get taken off the top of the already painted (presumably creme coloured) finished wall, and done, looks like a brand new wall, when its just been covered up the whole time.
similar with the honeymoon suite/latecomer bedroom, they basically just use easy hang wallpaper and different furniture arrangements to transform the rooms and make them look completely different
