Here is an unsettling question: Our population and our cities are growing. How will we handle our needs for sustainable housing? Here is one solution... In this talk Eef Tanghe explores the widely varying benefits of living together in more tightly knit co-housing communities. Eef Tanghe is a manager for Cohousing Projects, a cooperative that supports people to build their own cohousing community in Flanders. While initiating her personal project near Ghent, she acquired expert knowledge by hurdling many obstacles and visiting other communities in Belgium and abroad. Today, more than 20 groups of neighbors rely on her financial, architectural and legal advice to get their own community up and running. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
