AN ECO house that generates its own solar and geothermal energy has gone on the market for £2 million.

The stunning pad also has a wireless camera security system and built-in audio speakers which can be controlled by an iPad.

The five-bedroom home, called The Spiral, in Worth, near Crawley, is set over 4,000sqft and has an open-plan kitchen diner and living room, a wood-clad corridor and a dressing room.

Sliding doors open to a landscaped terrace where there is a built-in hot tub and a lowered fire pit surrounded by stone benches.

The unusual property is surrounded on the outside by a path which branches off from the private drive and curves around the semicircular home, leading to the round entrance door.

It has a recovery ventilation system which supplies fresh air while making sure no heat is lost.

The current owners have spent 18 months designing and building it.

It is being sold by estate agents Hamptons International.
