The Government is working with organisations including Network Rail, the BBC and Royal Mail to identify disused sites that could be used for housebuilding.
Housing minister Grant Shapps revealed that enough Government land to build 80,000 homes has already been identified and that minsters are aiming to release enough for 100,000 homes by 2015.
Mr Shapps also announced the allocation of the £500 million Growing Places Fund to 39 local enterprise partnerships, which will create thousands of jobs in construction and related industries.
As well as this, £45 million from the Get Britain Building Fund will be allocated to unlock 18 of the most difficult stalled sites in the country, with the aim of delivering 1,301 homes.
Mr Shapps said: “With the Prime Minister putting housing centre stage on the road to economic recovery, I am determined that we shall not repeat mistakes of the past.”
