Speaking at the Labour Party conference in Bournemouth today (24 September), the Prime Minister said that he would oversee the inception of 10 of the so-called 'Brown Towns' - up from the five he promised in July.
In March Housing Minister, Yvette Cooper, announced government plans to build the zero-carbon settlements on brownfield sites.
Four months later the then-chancellor pledged that he would build five of the towns should he be voted in as Tony Blair's successor. The first of them - by Arup Urban Design - was unveiled in June (Arup reveals pioneering 'Gordon Brown green town') and is for Northstowe in Cambridgeshire.
It includes 9,500 homes and is being driven by English Partnerships and Gallagher Estates.
The fist phase of the scheme is due for completion in 2016 and will include 4,800 houses.
