People pass a shopping centre at Elephant and Castle south London, Britain October 5, 2015. In the past decade, 50 social housing estates with 30,000 homes have been regenerated across London. The total number of homes on those locations has doubled, but with a net loss of 8,000 homes available for the lowest social rents. Supporters say regeneration schemes create more and better homes in a city facing a housing shortage and eye-watering property prices. Objectors say they lead to social cleansing, with poor Londoners priced out as neighbourhoods go upmarket. REUTERS/Neil Hall
