Providing sufficient affordable living space—especially in European conglomerations—is one of the great challenges of the future, requiring new solutions. In the face of demographic change, changing family structures, and a growing environmental awareness, completely new residential forms have evolved in Europe: cross-generational residences, residential cooperatives, housing projects for senior citizens, ecological estates, integrative residences, or district neighborhoods. The significance of communal living, in particular, will change in light of social traditions and framework conditions such as housing policy and the housing market. This book provides an insight into communal living in eleven European countries—Austria, the Netherlands, France, Great Britain, the Czech Republic, Denmark, Sweden, Norway, Finland, and Germany—and presents a range of exemplary residential projects with their architectural and social concepts, as well as their different funding schemes.
