Housing activists construct a barricade on the Sweets Way housing estate close to the home of its last surviving resident, Mostafa Aliverdipour, on 23rd September 2015 in London, United Kingdom. A group of housing activists calling for better social housing provision in London had occupied some of the properties on the 142-home estate in Whetstone, in some cases refurbishing properties intentionally destroyed by the legal owners following eviction of the original residents, in order to try to prevent or delay the eviction of Mr Aliverdipour and the planned demolition and redevelopment of the entire estate by Barnet Council and Annington Property Ltd.
