138th Secondary School “Prof. Vasil Zlatarski”

The Urban Lung – From Asphalt Fortress to Breathing Ecosystem

The Manifesto Context The era of the school as a closed, asphalt-heavy institution is over. At 138th Secondary School, we are moving “Beyond the Gates” to replace restrictive boundaries with a vibrant social ecosystem. This project is not a mere renovation; it is a surgical re-engineering of the urban DNA, proving that architecture is the most powerful tool for neighborhood connectivity.

The Architectural Intervention Faced with a polarized debate between the need for professional sports facilities and a desire for lush greenery, our design acts as the ultimate mediator. We refused to choose. By intelligently scaling a high-performance sports hub—featuring an adaptable football pitch and athletics track—we preserved enough space to transform the remaining barren asphalt lot into a multi-functional green park.

The New Academic Wing We have built the school’s missing “heart”: a new academic wing housing a light-filled atrium and a massive 915 sq.m sports and assembly hall. Designed with modularity and the future in mind, the interior features flexible layouts that can evolve with educational needs. Crowning the structure is a unique rooftop “Green Terrace,” an outdoor classroom where students learn through direct contact with nature.

The Urban Accumulator This project redefines the school as an Urban Accumulator. Through strategic layout and independent entrances, the large-scale sports base is safely “unlocked” for thousands of local residents outside of school hours. We have replaced the “heat island” of the past with a high-energy urban hub where the school and the neighborhood finally breathe together.
