Cohousing is a new form of human settlement which offers a possible solution to the housing crisis. In cohousing communities, people come together and share facilities and belongings, such as a garden, central workshops and car. The energy efficiency contributes to a reduced cost of living for tenants. Equally, cohousing and its community have the potential to offer a different scale of social organisation whilst delivering an environmental concept that leads to a low carbon lifestyle. This paper will present work conducted as part of a PhD study which aims to examine the timeline and consequences of a green agenda moving towards a sustainable living model, by exploring debates around cohousing and sustainable communities and social interaction. Examining people’s contemporary lifestyles as a starting point, this research will develop methods to encourage a greater commitment to cohousing and sustainable living environments. This paper will review two case studies in order to examine the role of cohousing in creating sustainable living environments in the UK. Cohousing concepts will be analysed according to size and features, community structures, cultural and economic values.
