Why is there a bath just sitting by itself on a landing? Who would want to bathe in full view of the rest of the family? Not me!
Having had a look at the floor plan because I thought exactly the same, it's actually part of the flipping enormous master suite, so it is private and behind a bedroom door.
I agree though, the photo makes it looks like it's a landing by the stairs. In fact a lot of the photos are really awful. OK, there's no disguising the mind melting paintwork but the bones of the layout aren't that bad if they were photographed properly.
For example, why haven't they picked up the bog brush & bottle of bog cleaner because photographing the toilet area!!
