What STOA Groupe does

STOA Groupe is a privately held French real estate developer headquartered in Bordeaux, operating as a SASU under the legal stewardship of Aurélien Achille Marconi. The group is organized into four wholly-owned subsidiaries — STOA Promotion (new-build development), STOA Agence (transactions, rental and co-ownership management), STOA Rénovation (heritage rehabilitation), and STOA Bâtiment (renovation project management) — and delivers a human-scale product line of new-build and renovated residential properties (apartments, houses, mixed-use units) typically capped at 50 units per program. The platform is regionally concentrated in Nouvelle-Aquitaine, spanning Bordeaux Métropole, Bassin d'Arcachon, Pays Basque, and Charente-Maritime, with a dedicated regional office in Biarritz and a combined team of 27 employees.

The group's core technical and methodological differentiator is its co-construction personalization model, which embeds buyer-driven customization of floor plans, materials, finishes, and optional smart-home features (DeltaDore, Porcelanosa, Circouleur, Hitachi) into the RE2020-compliant construction process. It is paired with an explicit RSE (CSR) roadmap emphasizing biosourced materials and environmental performance, and a mixed-tenure structuring model in which 40–70% of units per program are allocated to social rental, social accession, or intermediate housing via partnerships with established bailleurs sociaux (Domofrance, Erilla, 3F) and Bail Réel Solidaire (BRS) mechanisms.

Commercially, STOA runs a sales-led go-to-market combining direct field sales, an in-house agency, and a referral network of banks, notaries, and financial partners. Revenue is generated primarily through one-time VEFA (off-plan) sales of new-build units and renovated properties, with a recurring managed-services layer from STOA Agence's rental and co-ownership management. Approximately 50% of 2024 programs are pre-sold to institutional social landlords, which secures construction financing and enables project launches; the remaining pipeline is sold to individual primary-residence buyers, first-time buyers (primo-accédants) using PTZ/BRS schemes, and buy-to-let investors using LMNP, LLI, and residual Pinel inventory. Average production is roughly 250 new units per year, scaling toward approximately 350 units across 8 programs in 2024.
