Green City

Friedman elaborated on the idea that cities are very much in need of public green space. This amenity is extremely expensive as the use of cityspace for greenery is often understood as unused space that must be payed for out of developments of buildings. Hence the accomodation in cities with a lot of public green space is also expensive.

Section and bird’s eye view of the Green City principle, Yona Friedman, 1979

By using the principles of the Ville Spatiale it would be possible to integrate space for greenery over the floors of the structure, or use the structure exclusively as a park or a public garden. It would also be possible to regulate the temperature in winter by adding glass screens as in a hothouse. In an inhabited Ville Spatiale structure it could be made mandatory to reserve 30% of the useable space for gardens.
