At the Winkerlaan in Utrecht, Dutch architecture firm EVA architecten has completed SO Fier, an energy-neutral primary school for Special Education Cluster 2 students that emphasizes sustainability, flexibility and connections with nature. The school, which belongs to SPO Utrecht, is split into two volumes — academia and a gym — that read as a single mass thanks to the continuous brick masonry that wraps around the facade as well as the rounded corners that soften the building’s appearance.
