It's not a pool up above. The floor would cave through with the concentrated water pressure. The upstairs at Elstree is useless anyway. It's all pipes and wires. Can't see them building a staircase and going to the huge technical effort of building an upstairs room just for the final series.

There is already a jacuzzi type thing outside anyway. I know the house is going to be amazing but come on.
