A "stunning" energy-efficient home has been constructed in south Devon, the Telegraph reported this weekend.

The green home is a conversion of a 1970s T-shaped house, constructed underground to improve its eco-friendliness.

Highly energy-efficient, the earth-sheltered green home is built into a hillside overlooking the River Dart. The result is a sound-proof green home that saves up to 80 per cent of its energy costs as it is warmed and cooled by the earth, the newspaper claimed.

According to Mike Inness, an architect from Harrison Sutton Partnership, the unique home has "the wow factor".

"In all our projects now, clients want a sustainable home with features such as rainwater collection, pellet boilers and heat-recovering ventilation systems," he said. "This house takes that eco-awareness one step further."

The house would be ideal for "a keen fisherman or someone like a pop star", Peter Symons from Stags in Totnes told the newspaper, adding that its underground aspects offer an acoustic advantage and added privacy.

According to Sustainable Build, there are fewer than 100 underground homes in the UK.
