This monograph by architecture critic Hans Ibelings sheds light on the little-known work of Dutch architect Gert Boon, who steadfastly adhered to his principle of seeking coherence through geometry. Belonging to the same generation as celebrated names like Aldo van Eyck, Herman Hertzberger and Piet Blom, he held very decided views but rarely aired them in public. Boon's work and career are documented here on the basis of his projects and archive at the Netherlands Architecture Institute, with specially commissioned photographs of buildings and interiors, such as holiday homes in Bergen, a school in Marken, a large housing complex in Arnhem and private houses.
