No there isn't. Building developers like to have a five year land bank, which I think is reasonable. Councils can compulsorily purchase land and buildings, but only in certain restricted circumstances. The problem is there has to be a market for builders to sell into. I say market advisedly because it is not the same as need.
Our local Council has got into a lot of problems for not meeting its housing targets. Building on a very large development area (1000 plus houses) slowed down drastically during the recession because people were uncertain of the future so were wary of either buying their first house or trading up and with mortgage companies being much stricter about lending criteria, the market almost dried up. the need for housing, of course, did not.
