Land is scarce in Britain. Living on an island world power has its advantages and its disadvantages. On the one hand, there’s plenty of Irish whiskey, but on the other hand, London has per square foot some of the most expensive real estate on the planet. It’s a balancing act. 

One residence that walks that linen quite discreetly is this subterranean mansion in Cheshire England (where the cat is from!). This 4,300 sq. foot residence is almost entirely underground. Below the surface is a veritable cave of wonders including the following: Entrance hall, cloakroom/WC, lounge, dining room, breakfast kitchen, utility room, laundry room, master bedroom with en suite bathroom, dressing room & chute to pool, 2 further bedroom suites, swimming pool, central Jacuzzi with atrium above, gym, bar area, changing room with shower & WC, plant room, garage

Obviously some Dennis the Menace type man-child had a hand in designing this secret layer because its best feature is definitely the waterslide that starts in the master bedroom and ends in the pool. And all of this just a little over $3 million U.S. dollars. Via Country Life
