The architecture and planning companies in Occitanie are primarily mid-sized firms, many founded in the late 20th and early 21st centuries. They specialize in urban development, infrastructure, and sustainable design. Urbanis focuses on revitalizing private housing, while GROUPE BETEM provides multidisciplinary engineering services. GROUPE SERM/SA3M manages urban development in Montpellier, and Oppidea Europolia handles urban planning for Toulouse Metropole.
A notable pattern among these companies is the prevalence of headquarters in Toulouse and Montpellier. Several firms, including ISAURE transforme un sujet immobilier en Projet Humain and Maison Tournesol, emphasize sustainable and human-centered design approaches, reflecting a regional focus on ecological and social responsibility in development.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
