The Government have a target that 80 per cent. of new housing in the Thames Gateway should be built on previously developed 'brownfield' land. The Thames Gateway Delivery Plan, published in November 2007, confirms that, since the inception of the Sustainable Communities Plan in 2003, that target has been exceeded and the Government are committed to keeping to the target over the next three years at least. Figures for the number of dwellings built on brownfield land in Thames Gateway for 2007 as a whole will not be available until later in 2008.
