What role can interiors play in adapting to the rapidly changing lifestyles of our cities’ inhabitants? Resulting from a study project carried out at the Geneva University of Art and Design (HEAD – Genève), Renewing the city from the Within formulates alternatives to the urban development model centered on building expansion, by proposing scenarios for the renewal, from the inside out, of existing collective housing buildings in Geneva. By analyzing a sample of collective housing buildings from the three main periods of the city’s development, the publication develops scenarios aimed at adapting these typologies to a convivial and mixed lifestyle, based on principles of solidarity, hospitality and sharing.
