Stiftung trias was established in 2002, to help community groups and co-housing projects access financing. Trias takes land off the market by separating the ownership of land and buildings: supported initiatives lease the land from the foundation in the form of a long-term Heritable Building Right and their lease fee is collected in a mutual fund run by Trias. In recent years, Trias has also been working with public administrations, securing functions for properties that municipalities are obliged to sell under austerity laws.
