The renovation of the Lille Faculty doesn’t erase the past, it builds on it. Two modernist buildings from 1967 are reinterpreted with the ambition to meet contemporary environmental standards. The project aims to turn dysfunction into demonstration by reworking the architectural language of the original structures. The vertical rhythm of the main building returns as a series of deep-set white aluminium fins, parametrically tuned to orientation and sun exposure. A verdigris-toned metal skin reinterprets the original façade, combining memory with performance.

Le Galien, the smaller wing, gains a more distinct presence through a layered façade system, using iridescent finishes that animate its surface with shifting light and shadow. Rather than treating renovation as routine, the project explores what informed reuse can offer. Over 70% of construction waste is reused, and each square metre integrates 3 kg of bio-sourced materials. The result is a façade system that filters heat, enhances natural light, and contributes to a projected 60% reduction in annual CO₂ emissions. Lille Faculty is part of the France Relance program and aims to serve as a demonstrator for how public buildings can evolve toward low-impact futures.
