The go-ahead has been given for renovation work on the high-rise residential building at 14, Rue des Troncs, Serrières. Working closely with representatives of the general contractor, prévoyance.ne, and an interdisciplinary team with experience in this kind of approach, a strategic working plan has been specifically developed to renovate the building and improve its energy performance while preserving its expressive, typological and architectural character. The approach involves a series of interventions on the building’s shell and common areas, as well as complete renovation of the kitchens and bathrooms of the 50 flats concerned.
