De Warren is the first newbuilt housing cooperative in the Netherlands, located in Amsterdam. It is where I live and am a cooperative member. The building was developed by the future residents themselves, with a strong focus on social and ecological sustainability, and affordability. I am part of the Social Architecture circle, where I work on activities, governance, and mediation. My role includes facilitating general assemblies, helping to resolve interpersonal conflicts, and organising parties and events, so that we can live together in a way that feels good for everyone.
since 2023
De Warren is home to around 50 residents living in 36 apartments. One third of the building is dedicated to shared facilities, including a multipurpose room for sports and dance, a co-working space, a recording studio, a chill room, extra kitchens, and guest rooms. I really enjoy knowing everyone in my building, sharing meals, inventing elaborate parties, hosting living room concerts, and never quite knowing where all the cups go.

Alongside the social side of things, sustainability was a central ambition from the start. The building uses a timber hybrid structure, reused materials, living facade, renewable energy systems, and is energy positive. The cooperative model allows residents to keep rent prices low and stable over time to pay off the mortgage together, because the building is not run for profit.

De Warren is what I would describe as a more mature community. Not only literally, by being already physically built, but also because over the years the way we organise ourselves has settled. People know each other well, and responsibilities are clearly distributed. We use Holacracy to structure our decision making, and clear communication channels are in place to keep things transparent and organised. Residents actively contribute their time, both to maintain the community itself and to organise activities for the neighbourhood and the public. It just works.
De Warren is an important reference for my other projects. Many things have been tested here, so there is a lot of knowledge and experience to draw from. It reminds me that collectivity is not an ideological pipe dream, but something grounded and real.
