This is a network of local authorities, across the country, which promotes cooperative principles and innovation in local government. The network has established a ‘Housing Commission’ to look at how cooperative and community based organisations might provide solutions to the housing crisis. The Commission is being led by the London Borough of Croydon. This evidence-gathering session in Croydon was attended by many officers from different London boroughs, as well as organisations promoting community housing solutions in London and beyond. PHASES were invited as one of a small number of organisations actually generating community housing in London. The network will report in September 2017 but in the meantime Croydon are hosting a good practice website and blog which will feature PHASES, amongst other organisations.
