Private Sezin School Open Roof Space is a ‘beyond-classroom’ pedagogical space with a spatially hybrid program that fosters meeting, making, learning and working. To this end, the design team at ATÖLYE intervened in a lightweight yet effective manner and chose the formerly dormant empty rooftop space of the school, measured at approximately 1,700 m2 within 15,000 m2. In terms of furniture, the team developed its existing CNVS furniture line with modular and flexible products. Ranging from acoustically isolated hub structures to mobile bookshelves and stand-up work tables, the bespoke furniture portfolio allowed for permutational layouts. Collaboration with British startup Open Desk, an open-source furniture system, added diversity to the portfolio with its CNC fabricated models. All furniture was manufactured with FSC-plywood, low-impact felt, recycled sponge and recycled steel. Ecological wood wool panels were placed across the ceiling surface to reduce reverberation and increase intelligibility in different learning settings, while serving energy efficiency goals. Architectural nuances including wide corridors for spill-out usable spaces, no-shoe zones for informal interaction, elevated platforms for focused work, writeable wall surfaces, and acoustic windows provided spatial diversity. The designed space suggested all users to become actants rather than passive observers.
