MARSEILLE
Marseille is in the midst of one of the most consequential construction periods in its modern history, as the city simultaneously tackles a large-scale social housing renovation backlog and delivers ambitious new development along its evolving port periphery. The Aix-Marseille-Provence Métropole, the largest metropolitan authority in France by surface area, has committed €2.1 billion to construction-related programmes over the 2026–2029 period, placing the region among the most active construction markets outside the Île-de-France.
The Euroméditerranée regeneration zone — France's largest urban regeneration operation outside Paris — continues to expand in 2026. Phase 2 of Euroméditerranée, covering 168 hectares north of the Old Port, is now well into its delivery phase, with 11 major construction projects currently active including office towers, social housing blocks, a new secondary school, and a €220 million data centre complex that represents the largest single-building investment in the zone to date.
Social housing renovation is an urgent priority. Marseille's housing stock includes some of the oldest and most thermally inefficient social housing estates in France, and a dedicated renovation programme — La Marseille de Demain — is targeting 15,000 apartments for deep energy retrofit by 2030. The programme is funded through a combination of state grants, metropolitan subsidies, and housing association investment, and is generating sustained demand for external wall insulation contractors, mechanical ventilation specialists, and low-temperature heating system engineers.
Mediterranean climate adaptation is shaping new building standards. Increased frequency of extreme heat events has prompted the Bouches-du-Rhône departmental council to issue new supplementary building guidelines requiring all new residential buildings to include enhanced thermal mass, strategic shading devices, and natural cross-ventilation pathways. Architects report that these requirements are fundamentally changing the plan form and section of new apartment buildings across the city.
