In recent years, the locally protected primary school building on Kiscelli Road has expanded with the addition of a five-year high school. The Alternative Secondary School for Economics is progressing in stages to develop the necessary infrastructure to accommodate the growing student body and specific curriculum requirements.

The planning and consultation process has taken place in multiple phases and continues to evolve. Numerous designs and layout sketches were created to address the expansion needs. In the first phase, the attic was converted, and a new elevator tower was constructed. The second phase, completed at the end of 2024, involved the addition of a third-floor extension, ensuring that each grade level now has an adequate number of classrooms and dedicated communal spaces.

According to the heritage preservation study, modifying the original rooflines significantly altered the building’s overall appearance, and reinstating them would strongly reinforce its original character. For this reason, during the first two phases, we opted for extensions that reflect the original design seen in archival photographs while integrating the school’s functional needs and contemporary architectural language.

The third-floor addition was constructed as a lightweight steel structure positioned behind the preserved original railing. The continuous glass surfaces follow the architectural rhythm of the existing building, with their transparency echoing the original wooden cloister.

The flat roof, maintaining the cornice line of the central building, accommodates the solar panels that were previously installed on the terrace. In terms of spatial organization, the two wings are nearly symmetrical. Facing the street façade, two larger classrooms have been added on each side, directly connected to a communal space equipped with a kitchenette, lounge, and storage lockers—an area shaped collaboratively by teachers and students. A bright corridor leading to this space provides access to additional breakout rooms, a small laboratory, and specialized development rooms.
