Assembly

What Assembly does

Assemblia is a Société d'Économie Mixte (SEM) headquartered in Clermont-Ferrand, France, created on January 1, 2020 from the merger of Logidôme (a social housing landlord) and Société d'Equipement d'Auvergne (SEAu, an urban development and economic-park specialist). It is described as the first multi-activity SEM in the French housing sector and operates as an integrated urban development platform serving the Clermont-Ferrand metropolitan area and the broader Auvergne territory from Moulins in the north to Brioude in the south. The company is majority-owned by Clermont Auvergne Métropole, with additional public and private shareholders including Riom Limagne et Volcans, Ville de Clermont-Ferrand, Caisse des Dépôts et Consignations, and Caisse d'Epargne.

The company's operations span three core revenue streams. First, social housing rentals across approximately 10,000 dwellings in the Clermont-Ferrand metropolitan area, regulated under French social housing framework (PLAI, PLUS, PLS categories), with around 900 units allocated annually through a housing allocation commission and ongoing tenant management via the "Assemblia et moi" extranet portal. Second, property development and sales, including new-build construction, residential land parcels, and serviced habitat plots, with home ownership facilitated through the wholly-owned DOMIA cooperative subsidiary and commercial/industrial land sold via economic zones such as ZAC des Gravanches, ZAC de Julliat Est, and Parc des Montels. Third, public infrastructure and urban development services delivered under Assistant à Maîtrise d'Ouvrage (AMO) mandates for local governments, including sports complexes (Stade Philippe Marcombes €37M), aquatic centers (Centre Nautique de Chamalières €11.5M), and other community facilities. The company also operates a renewable-energy subsidiary, Ombrières d'Auvergne, which deploys solar parking canopies in partnership with See You Sun and Crédit Agricole Centre France.

Assemblia employs approximately 200–220 staff across operational, financial, habitat, territorial development, and tenant-services functions, supported by four physical offices (Clermont-Ferrand headquarters and Saint-Jacques, Pardieu, and Allier branches). Customer segments span residential tenants, individual property buyers, local governments and public authorities, and businesses acquiring commercial or industrial land. Distribution is conducted entirely through direct channels — the application portal, tenant extranet, DOMIA advisors, and direct public-sector engagement — with no intermediary or reseller layers. There is no proprietary technology platform, no disclosed AI capability, and no external funding rounds; revenue is not publicly disclosed, but portfolio scale, project pipeline, and headcount are consistent with a €100M–€250M annual revenue band for a regional French SEM of this profile.
