The Bospolder-Tussendijken district in Rotterdam is one of the five poorest areas in the Netherlands. However, it has a lively social fabric. Many strong family and informal networks offer people a safety net when they are in difficulty. The announcement of a private heat network in the district prompted the development of an alternative approach that would enable local residents to become co-owners, a Local Energy Action Plan. One of the pilot projects in this plan is the redevelopment of the ‘Dakparkschool’ and the building block’s inner yard, which could become exemplary for other (public) buildings in the district. The renovation of the school building, installation of solar panels and depaving of the playground are the entry point to future-oriented classes for the pupils and the mobilization of their parents and neighbours in the energy transition. OOZE developed this spatial, financial and organizational design strategy as part of the International Architecture Biennial of Rotterdam Atelier between 2018 and 2021.
