UK firms Huntsmere and NC Homes developed the Perdu mansion, which is listed as an available property with a guide price of £2 million; however, it’s possible the home has already been sold. According to Messenger, Huntsmere opted to build beneath ground to avoid the development restrictions in the Bowdon conservation area, a decision that had been approved by Trafford’s planning committee. The underground home features a radial plan arranged around a central atrium that, in addition to four ground-level light wells, let in natural light.

The underground home is accessed through a “classical garden folly,” a privet garden enclosed by a manicured laurel hedge. A flight of stairs leads down to the first level that comprises the main living spaces including the kitchen, lounge, dining room, and master bedroom with dressing room and en-suite bathroom. The triangular and wedge-shaped rooms wrap around the central atrium. A second staircase also provides access to the second level, but more adventurous types can choose instead to take a waterslide from the master bedroom above directly down to a spacious swimming pool fed by an 8-meter-tall and 12-meter-wide wall of water. This lower leisure area also includes a pool bar, changing rooms, jacuzzi, gym, and two extra bedrooms, both with dressing room and en-suite bathrooms.
The innovative Perdu house also purports to incorporate the highest standards in renewable design to achieve nearly net-zero energy. The environmentally friendly elements include a ground source heat pump, state-of-the-art ventilation and heat recovery system, rainwater harvesting, solar tube system for hot water, and an energy-efficient lighting system with low-energy light bulbs that consumes 80 percent less electricity than a standard system. Since the building is underground, the house also benefits from the earth’s insulating properties to keep warm naturally in the winters while staying cool in summers.
