Designs for the first UK housing development to achieve level six of the Code for Sustainable Homes have been unveiled by developer Barratt.
The 200 home development will be built at Hanham Hall near Bristol by 2011 as part of English Partnerships Carbon Challenge programme.
The development features a combined heat and power plant for all homes and commercial premises on the site.
It will be fuelled by wood chips or pellets and the energy generated will be carbon neutral. It will also have a sustainable urban drainage system which will ensure that the rainwater run-off is half that of an average greenfield site, and existing landscape features such as hedgerows and trees are being retained.
An additional one kilometre of new hedgerows will be planted to assist the ecology of the site.
