42UP by AR Studio d’Architectures doubles a Paris school's capacity without expanding its footprint, turning constraint into an opportunity. The project builds five lightweight levels above the preserved 1962 structure, supported by a 42‑meter beam freeing the third floor. A white aluminum skin unifies old and new, filtering light and heat. Inside, open, flexible spaces reflect School 42’s open pedagogy. 42UP stands as a manifesto for density, renovation over demolition, and inclusive, sustainable urban learning.
