I'm not convinced London has a housing shortage. Or the UK for that matter. The problem is that anyone can buy a house in the UK and they've become investment vehicles. Also consider London has just reached its pre-WW2 population, and all the properties bombed most likely replaced by more efficient housing.
I found a study about supply and demand for housing, but am struggling to find it. There's a post here which seems credible enough, related to the topic:
