Mutualization, flexibility, and modularity of spaces, as well as generational, social, and functional diversity within a place, are the foundations of the restructuring of a neighborhood project. Our architecture contributes in several ways to create the conditions for inter-generational living. The hybridization in the same place with multiple functions, offerings, and activities intended for seniors, professionals, students, and families, and the mastery of this typological mix, are key factors for success in this project. Our programmatic approach aligns with the ambitions of the City of Luxembourg and the history of the site. The goal is to create a space dedicated to culture, urban sports, commerce, and inter-generational and inclusive activities.
