The series of five car-free settlements – called Sky Village, Wilderness Village, Meadow Village, Cape Village and Sea Village – will provide a year-round community for 15,400 residents on a site near the north-eastern town of Byala.
The resort scheme – for developer Byala Beach Resort – will also feature a lakeside spa, an activity centre, a sports park, restaurants, shops, and a 220-berth marina.
Residents will be encouraged to leave their cars in the underground car park at the entrance to each village, and to use the electric shuttle buses, electric pool cars and bicycles provided.
Other sustainability strategies include using biofuels to power the CHP plant used to provide year-round power to the five villages.
A spokesman for Foster + Partners said the scheme is 'informed by the vernacular architecture of the region.'
The spokesman added: 'The hill towns have narrow streets with a tight grouping of residences, which creates environmental benefits such as reduced wind speeds, as well as providing sunny balconies and cool streets.'
The scheme's frst phase, the Sky Village, is due on site in 2009 and is expected to complete in spring 2011.
