The Dutch municipality of Brummen needed a new town hall. The solution turned out to be a Turntoo building: The Brummen Town Hall is built with consistent use of reusable and renewable high-quality construction materials, and a contractual approach that guarantees circularity at the end of the intended use period. The supporting structure, façade and floors are made from wood in pre-fabricated components. The use of concrete has been minimized. The wooden components can easily be dismantled and reused in a new building. Interestingly, manufacturers requested several minimal yet important design changes so that the components could be used more easily in their second-life application.
