Open Roof Space Project was designed as a pedagogical space with a spatially hybrid program that fosters meeting, making, learning and working. To this end, borrowing from Fuller’s trimtab concept, the project intervened in a lightweight yet effective manner and chose the formerly dormant empty rooftop space of the existing building, measured at approximately 1700 m² within 15000 m². This scale difference allowed for experimentation while offering sufficient room for a critically diverse program.
