Located along the Saigon River, opposite the city’s development symbol – Landmark 81, Hyperhall is a renovation project that transforms an old factory into a basketball court for youth. Inspired by the city’s vibrancy and the industrial nature of the current situation, we proposed a modern metal shell that envelops the entire old factory. The structure is preserved while meeting the typical functional requirements of a FIBA-standard basketball court. Additionally, the mezzanine has been expanded to create an observation and cheering corridor for spectators, along with a small food and beverage space.
