The 520m2 project near the town of Carcassonne, called Brau House, will be planned in two phases, comprising a six-bed main house, and a four-bed guest wing.
According to Robert Dye Associates, the scheme 'grows' out of the hillside, leading the eye round the site to the vineyards below, and the mountains north and south.
From the drive, the ground plane extends as a 'giant roof deck' providing a viewing platform, shading and access to the lower living spaces, and fully sliding glass wall to the east.
The practice will use gabion walls and poured concrete to achieve structural solidity, thermal mass and 'defence against termite attack'.
The house will also employ solar panels to provide heating and hot water, and rainwater will be collected for grey-water use.
The practice hopes to have the first phase completed by next year.
