The Twenty-First Century Academy for Community Leadership (P.S./I.S. 210) in New York is a kindergarten-to-Grade 8 school. Since only a limited footprint is available in this crowded metropolis, the schoolyard was built on the rooftop. Curved steel columns hold the X-TEND stainless steel mesh in position. The installation work on site was supported by CARL STAHL ARCHITECTURE’s experienced assembly team.
