The paper investigates how rethinking domestic care spaces—especially kitchens—can enhance housing affordability and promote collaborative living. Drawing from feminist and critical spatial theories, it examines how food-related spaces can challenge capitalist home models and support collective care. Through two French case studies (Symone de Cyrène homes and La Ferme du Rail), the essay explores how shared kitchens enable flexible living arrangements and social negotiation. It concludes by discussing two key challenges: ensuring equitable participation in shared care work and designing spatial strategies that extend domestic care into broader urban infrastructures.
