The Structuralist Architectural Drawing 1955-1980

During archival research into the work of architects such as Piet Blom, Jan Verhoeven and Herman Hertzberger for the exhibition Structuralism, we encountered drawings that deviated from the conventional plans, sections and elevations. Instead they comprised abstract structures, geometric patterns with bright colours, visualisations of network-like cities, grids, collages and booklets. Intrigued about the origins and significance of these drawings, curator Ellen Smit initiated a research project with the help of an NWO museum grant. What were these architects actually drawing and why in this manner?
