TRAFFORD's first underground house could be yours - for a cool £2m.

Work is due to get underway in the autumn to build a two-storey subterranean house - to be called Perdu - on land on St Margaret's Road, in the Bowdon conservation area.

Developer Huntsmere says there has already been a high level of interest in the property, which is due to be completed in autumn 2011.

Only the entrance of the house - in the form of a garden folly - will be visible from above ground, in the grounds of Limehurst, a Victorian mansion converted into flats.

Huntsmere decided to build underground because of the restrictions on any development taking place in the conservation area. The scheme was approved by Trafford's planning committee last September, despite objections from 29 residents and ward councillors.

Its features include a waterchute linking the master bedroom on the first floor to a pool below.

Chris Oakes, of Huntsmere, said: “This will be the first luxury subterranean mansion in the area. We are really excited about the development and I am confident that this house will become an architectural landmark, albeit one that most people will never see.”

The house will be laid out in a circular design around a central atrium and bathed in natural light from four ground level lightwells.

On entering the property a flight of stairs will take visitors down to the first level and in to the entrance hall. The main rooms on this floor are the kitchen, lounge, dining room and master bedroom. The rooms are triangular or cheese wedge shaped.

The second level includes the pool area, a gym and two bedrooms.

It promises to have strong eco-credentials with a ground source heat pump providing underfloor heating, a solar tube system for hot water, while a rainwater harvesting system will reduce water consumption. A sophisticated lighting system combined with low-energy light bulbs will reduce electricity use.
