Trois Moulins Habitat

What Trois Moulins Habitat does

Trois Moulins Habitat (TMH) is a French social housing operator (bailleur social / ESH) and property developer primarily established in Seine-et-Marne (Île-de-France) with a secondary presence in Occitanie (Aude and Pyrénées-Orientales). As a subsidiary of Groupe Polylogis, a reference social housing group with ~60 years of operations and approximately 80,000 housing units under group management, TMH manages 19,493 social housing units housing 47,702 residents. The company's core business is the construction, renovation, and rental management of affordable housing (HLM) targeting households with modest incomes, complemented by property ownership programs including PSLA (location-accession with progressive ownership) and VEFA (off-plan purchase), as well as resale of existing units with 10-year buyback and reletting guarantees.

TMH operates a proximity-based service model through 3 agencies and 7 management antennas embedded within housing estates, supported by digital infrastructure including an online tenant portal (Espace Locataire), dematerialized rent billing (with 55% of rent invoices now sent digitally), and the national SNE housing application system. The company deploys BIM (Building Information Modeling) for new construction projects — notably an experimental 152-unit program at Pringy (Seine-et-Marne) — and operates under group-level systems including the Lylo quality management referential and ISO 50001 energy management certification. A partnership with Camarage (formerly Homiz) extends service offerings to include intergenerational cohabitation matching between senior tenants and students.

TMH's revenue model combines three streams: regulated recurring rental income from 19,493 housing units (the primary revenue driver), one-time transaction revenue from property sales under PSLA/VEFA programs, and public financing from government sources including ANRU for urban renewal, Action Logement, and local authorities (Seine-et-Marne department, Melun Val de Seine, Provinois). Rents are regulated and linked to state-set income ceilings (plafonds de ressources), with no agency fees charged. In 2021, TMH partnered with RLF to create DomusNostra, a state-approved coordination company pooling skills across a combined ~30,000-unit portfolio in Île-de-France, Aquitaine, and Occitanie. The company is led by Director General Gilles Sambussy, who also serves as Deputy Director General of DomusNostra.
