The Real Bat Cave

Check this out. Super-rich homeowners in London are building extensions to their houses underground to avoid conservation regulations on their old homes. Huge, underground, 50 ft. deep extensions for pools, living space, and garages.

One home in north London even has a bespoke chute covered in a special slippery paint, which enables the owner, who loves swimming first thing in the morning, but hates the fuss of dressing, to step out of bed and slide straight into the water a couple of storeys below.
