This ia brilliant article. In my view the land supply argument in London is all post rationalised. The capacity studies were based on Borough targets which in turn are often (not all) based on historic supply rates.
There is enormous supply of land in London. Its just that we estimate low density where in fact there is a small city the size of docklands in Silvertown Quays but there is no central vision to support the acquisition and parcelling out of the development plots. Many valiant attempts have been made. But none effective.
Councils frequently refuse planning applications and where they approve them, often make them financially unviable.
That's why little is built. There is plenty of land. There is just no framework for achieving the development we need. Everything is stacked against it.
