The Edith Maryon Foundation (German: Stiftung Edith Maryon zur Förderung sozialer Wohn- und Arbeitsstätten) is a nonprofit organization founded in Basel, Switzerland, in 1990. The foundation is dedicated to removing land and real-estate property from speculation and ensuring their long-term use for social, innovative, and sustainable purposes. It makes its properties available to third parties for socially oriented housing, cultural, or workplace projects. The foundation’s main areas of activity are in Switzerland and Germany.
The foundation was established in 1990 by Christoph Langscheid, John Ermel, and Michael Riggenbach with an initial capital of 12,000 Swiss francs. It is regarded as a pioneer of mission and impact investing focused on real estate and land. In many of its housing projects, elements of the cohousing concept are applied.
The foundation is named after the English sculptor Edith Maryon, a close collaborator of Rudolf Steiner who initiated social housing for the coworkers of the Goetheanum. Over a generation, the foundation’s real-estate portfolio has grown to 166 projects, some of which are held through subsidiaries.
As of December 2024, the foundation’s total assets amounted to 343 million Swiss francs. Its growth has been largely financed through donations, legacies, and interest-free loans from numerous private individuals. Over the years, the foundation has also become an active grant-making body in the fields of art and culture.

Under the program title Housing Assistance (German: Wohnhilfen), the foundation has, since 2003, provided rental-deposit guarantees based on a solidarity fund. In total, more than 13,000 households in north-western Switzerland have been able to obtain a rental contract through this mechanism, with around 1,000 new guarantees issued each year.
In addition, the foundation operates a hardship fund (Härtefällefonds) in cooperation with the Christoph Merian Foundation and, together with the Canton of Basel-Stadt, manages on behalf of the Basel Housing Foundation a cooperative-share fund (Genossenschaftanteilfonds) designed to facilitate access to cooperative housing.
The highest governing body of the foundation is the Foundation Council (Stiftungsrat), consisting of five members. An advisory board of nineteen people supports the council. Day-to-day operations are carried out by the foundation’s office in Basel, which employs 19 staff members (as of 2025).
