Overview of Nantes Métropole’s Housing Initiative
Nantes Métropole, the governing body for the city of Nantes and its surrounding 24 communes, has published a comprehensive review of its local housing programme covering 2019‑2025. The report, produced by the municipal authority, outlines how the metropolitan authority acted as an “amortisseur” against the national housing crisis by deploying significant financial resources and policy tools to increase the supply of both social and affordable housing.
Scale of Housing Construction Achieved
Between 2019 and 2025 the metropolitan plan facilitated the construction of 7 400 new homes, of which roughly 4 000 are social housing units. The average annual authorisations amounted to 4 000 permits, falling short of the 6 000 target set in the original plan. About 80 % of the new dwellings are offered at regulated prices, and a notable portion were built using the bail réel solidaire (BRS) model, which allows purchase at 30‑50 % below market value.
Financial Commitment and Funding Sources
The anti‑crisis plan, launched in 2023, was allocated €50 million. Additional direct investments totalled €56 million for new social and affordable homes, while €141 million were spent on renovation of existing stock, covering 1 200 co‑ownership buildings and over 10 000 private dwellings. Over six years, €70 million funded the refurbishment of roughly 6 300 social homes.
Sustainable and Inclusive Design Features
Several projects incorporated environmentally friendly construction methods, such as a wooden housing cluster in Vertou built on municipally ceded land. These homes were sold for less than €300 000 for a 100 m² unit, illustrating a blend of affordability and reduced carbon footprint. The BRS scheme also limits speculative resale, supporting long‑term sustainability of the housing market.
Targeted Support for Vulnerable Groups
The programme prioritised vulnerable populations, delivering 700 new places in social residences, pensions de famille and emergency shelters. Specialised accommodation was created for seniors, young adults, and people with disabilities, including 178 units for residents under 30 and 130 temporary homes for fragile households, 22 of whom are children.
Progress on Social‑Housing Targets
The share of social housing in the metropolitan area rose from 22.49 % in 2018 to 24.99 % by 1 January 2025, approaching the 25 % minimum mandated by the SRU law. The BRS+ extension in 2025 added 270 solidarity‑ownership units to the stock.
Outlook for the Next Programme (2028‑2033)
A new Local Housing Programme (PLH) will commence on 1 January 2028, outlining ambitions for the next six years. The forthcoming plan aims to ensure dignified housing for all, promote construction that aligns price, location and sustainability, and improve the existing stock through regulated evolution. The metropolitan council expects to adopt the new PLH in December 2027 after two years of consultation with communes and partners.
