In the context of the transformation of the industrial PAV district in Geneva, and its presumed obsolescence, this project questions the rehabilitation of the Marbrerie 13 building and its heritage, rejecting tabula rasa and transforming it into social housing anchored in the existing structure.

Le Seuil is a dwelling designed for students seeking affordable housing and elderly people escaping isolation. It is composed of three porous grids, each establishing a threshold of intimacy between private and shared spaces, where each inhabitant defines their own degree of sharing.

Minimal architectural interventions make room for appropriation through furniture and for the definition of uses by the inhabitants. Shared spaces become places of encounter and spontaneous exchange, and encourage mutual support and intergenerational cohabitation, without imposing co-living, while respecting each person’s privacy and way of life.
