In most or all of the Mixed Communities Initiative Demonstration Projects (DPs), altering the mix of housing tenures and types is a central part of the regeneration approach. This short study looked at processes and outcomes of negotiations between the demonstration projects and developers on the specific mix of housing to be delivered. Three case study DPs were used: Canning Town, in Newham, London; North-East Coventry, in Coventry; and North Huyton, in Knowsley. These were selected to provide a spread of locations where negotiations were well enough advanced to provide sufficient case data.
