Problem addressed

Amsterdam faces a severe housing crisis, with rising prices and speculative ownership putting secure, affordable homes out of reach for many residents. Traditional market-driven models fail to deliver long-term affordability or empower tenants, who often have little influence over how and where they live. In this context, a group of young Amsterdammers asked how they could live more sustainably, socially and affordably, without treating housing as an investment asset. They identified a gap for non-profit, resident-led housing that guarantees stable rents, community governance and environmentally responsible construction over the long term.

Innovative solution

De Torteltuin is a housing cooperative in development where residents collectively design, build and manage their future building on Centrumeiland, IJburg, in Amsterdam. The cooperative keeps ownership and decision-making in the hands of the resident community, ensuring development, use and management are not driven by profit. Homes will be let at fixed, low rents, protecting residents from market volatility and treating housing as a basic right rather than an investment object. The new building is planned as energy-neutral, climate-resilient and nature-inclusive, combining shared facilities, democratic governance and long-term social value for both residents and the surrounding neighbourhood.

Key results and benefits

Since the first brainstorm in January 2020, De Torteltuin has secured an option agreement with the City of Amsterdam for a plot on Centrumeiland. In 2023, the cooperative obtained a development loan from the Stimuleringsfonds and produced a final architectural design together with Natrufied Architecture. A successful bond campaign has already reached its target of 500,000 euro, enabling the cooperative to move towards construction, planned to start in early 2025. These steps create the basis for long-term affordable rental housing, strong resident participation and a visible example of community-led, sustainable urban development in Amsterdam.

Potential for mainstreaming

De Torteltuin demonstrates how non-profit housing cooperatives can alleviate pressure on overheated urban housing markets while promoting social cohesion and sustainability. The model aligns with Amsterdam’s Action Plan for Housing Cooperatives and the city’s ambition to realise around 40,000 cooperative homes by 2040. Its governance structure, fixed-rent approach and use of bond financing via a separate foundation provide a replicable framework for other citizen-led initiatives. By showing that residents can co-design, co-finance and co-manage an energy-neutral, community-oriented building, De Torteltuin offers a practical blueprint for scaling cooperative housing in other municipalities.
