American Films With Unrealistic British Houses

221b Baker Street is a flat in a stately home, from the looks of things. Huge, clean and perfect, impossibly high ceilings. Baskerville Hall has stood in Dartmoor for generations....yet it looks like an Ikea Statikly Munshion

Looks like a standard semi-detached British house from the outside but it's a fucking MANSION on the inside. Imagine having that kind of footprint in London. It'd be worth putting up with the poltergeist activity...
