# The 30 largest Architecture and Planning companies in Paris
Tamtam tracks 145 Architecture and Planning companies headquartered in Paris. This list ranks the 30 largest by number of employees on LinkedIn, led by 脡cole, IDEA INC and OUI. Their median headcount is 153. Half of them were founded in 2000 or later.
The architecture and planning sector in Paris features a mix of established firms and younger studios. Companies like AIA Life Designers integrate architecture, engineering, and consulting with a focus on well-being, while INTERIOR specializes in high-end modular partition walls. Grand Paris Am茅nagement supports municipalities with land development, and Ateliers Jean Nouvel is a multicultural team working on diverse global projects. Many firms offer comprehensive services beyond traditional architecture, including urban planning, interior design, and product design.
A notable pattern among these companies is their diverse founding dates, spanning several decades. For instance, AIA Life Designers was founded in 1965, INTERIOR in 1981, and 脡cole in 2007. This indicates a continuous evolution of the architectural landscape in Paris, with both long-standing expertise and newer approaches coexisting.

## 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 11, 2026.
