In’li, a subsidiary of the Action Logement Group and the leading provider of affordable housing for employees and young professionals, and GA Smart Building, a low-carbon developer-contractor and specialist in off-site construction, signed an agreement during the Île-de-France Mayors’ Exhibition for a residential development of 58 affordable housing units in Thiais (94), at the foot of the “Thiais–Orly” station on Metro Line 14. This first partnership reflects their intention to work together on future projects and further develop off-site construction.
Located in the heart of a rapidly transforming district whose development is led by the EPA Orly-Rungis-Seine-Amont (ORSA), coordinated by Grand Paris Aménagement, the project will be part of a vibrant mixed-use environment combining housing, retail, and public facilities.
Developed through a co-promotion partnership between GA Smart Building and Société des Grands Projets, and designed by the architectural firm DREAM, the project will include a retail podium and 121 residential units of high architectural and residential quality, including 58 affordable housing units acquired by in’li.
This new residence will provide housing for employees and young professionals in the heart of the Paris-Orly airport employment hub, which supports 28,000 jobs and represents one of the major economic centers of Greater Paris.
The project is also pioneering in terms of off-site construction, featuring low-carbon concrete façades manufactured industrially by PREGA, GA Smart Building’s subsidiary, as well as semi-load-bearing stone construction. Thanks to off-site construction, delivery times will be shortened and site disturbances reduced, while ensuring high-quality execution and compliance with the 2028 threshold of France’s RE2020 environmental regulation. Project delivery is scheduled for 2029.
More broadly, over the coming months, in’li and GA Smart Building—both members of the Association Filière Hors-Site—intend to strengthen their collaboration to scale up off-site construction across France. Several projects are currently under review.
I am delighted with this agreement with GA Smart Building, which marks our first collaboration on a project of exceptional quality. Located in a rapidly transforming district of Thiais, at the heart of the Orly employment hub and directly served by Metro Line 14, this future residence will provide affordable housing for employees and young professionals. More broadly, GA Smart Building and in’li share the ambition of scaling up off-site construction to deliver high-quality housing while reducing timelines and lowering costs. Within the in’li Group, a subsidiary of Action Logement, we strongly believe in off-site construction and, as a residential property company, we aim to invest more heavily in off-site projects. This first acquisition from GA reflects our desire to work together on future developments.
I am delighted with this first collaboration with the residential property company in’li, which shares our conviction regarding the benefits of off-site construction in delivering high-quality housing within significantly reduced timelines. Developed in partnership with Société des Grands Projets and as part of the urban development programme led by EPA Orly-Rungis-Seine-Amont and coordinated by Grand Paris Aménagement, whom I thank for their continued trust, this residence will contribute to the transformation of a rapidly evolving district in Thiais, at the heart of the Paris-Orly airport employment area. It will help address the need to house employees and young professionals close to their workplaces, in low-carbon, affordable homes designed to meet contemporary needs.
