Housing costs in Milan continue to climb, widening the gap between income and house prices. The newest report by the Affordable House Observatory (OCA), which is being promoted by the Consortium of Workers' Cooperatives and LUM in collaboration with the Department of Architecture and Urban Studies (DAStU) of the Politecnico di Milano, indicates that low-middle-income workers are finding it increasingly challenging to access housing in the Lombard capital. The study, conducted by Massimo Bricocoli, Marco Peverini, and Lorenzo Caresana of the Politecnico di Milano, contends that a worker can afford to buy only 19 square meters, an employee 25 square meters, while a middle manager can purchase up to 48 square meters.  Even within the metropolitan belt, access to housing remains critical: an average wage is insufficient to purchase 50 square meters in many well-connected locations. Renting outside of Milan may appear to be the only sustainable alternative, but transportation costs and commuting time have a significant impact on income and standard of living. As a result, the research emphasizes the importance of a metropolitan plan that blends housing policies and transportation infrastructure in order to ensure accessible and sustainable solutions.
