This article reviews a decade of co-housing studies and publications, to identify major themes and research gaps. Generally, co-housing is seen as a promising model for urban development, and most empirical case studies report active and diverse communities, creating and maintaining affordable living environments. However, numbers are small and there is as yet no quantitative evidence to substantiate the claims. Nevertheless, important lessons can be drawn from co-housing as an integrated practice to meet today’s societal and environmental challenges. Rather than its utopian ambitions, the frictions with current institutional frameworks point the way to transform these into more adequate agents of development.
