In the 1950s and 60s, a school of Dutch architects emerged, which aimed to re-introduce the human scale into modern architecture. Their building designs were based on geometric structures, often composed of smaller units and with a possibility for future extension. The new architectural language was called Structuralism. One of the most iconic example was the orphanage by Aldo van Eyck, which could accommodate 125 children and now serves as office space. But there are many more examples of structuralist architecture in Amsterdam, from Herman Hertzberger’s Apollo Schools to Theo Bosch’ housing complex Pentagon.
