Zurich is a centre of global finance. Its real estate influences not only the rise of rent and property prices but also methods of extracting value from housing and residents. Switzerlands largest city also has a century-old commitment to public benefit and non-profit housing, implemented through a cooperative model of sharing resources.

In doing so, aspects of Zurichs model become transferrable to other places.
