The first definitive image has been released of what Barratt calls “the UK’s most sustainable development”.

Work began on Hanham Hall, near Bristol, last year. This is what it will look like in early 2011 when residents move in. The 6.6ha 195-home scheme will have its own biomass plant and will be the first large-scale zero carbon scheme to meet level six of the Code for Sustainable Homes. The engineer is Arup and the architect is HTA Architects.
