The Burwalls site is split into two halves, according to some of the estate agents' details I've looked at. This read section has some more modern-looking places where you can buy an entire house, if you're rich.
The mansion itself has been divided up into "lateral apartments". If you don't know what those are, you probably can't afford one.
