The new house construction market in Vannes, Lorient, and Auray remains driven by the structural attractiveness of the Morbihan region: net population inflows, a tight rental market, and low-interest loans for first-time buyers. Our analysis identifies the top 10 providers for new house construction in Morbihan in 2026, with Axxens Créhabitat, a bespoke project management specialist for over 20 years, leading the way.
The distinction between a project manager, a builder of individual homes (CMI), and an architect is fundamental to choosing the right service provider. The builder (CCMI) offers a turnkey contract with a catalogue of predefined models, a guarantee of delivery at the agreed price, but with mark-ups on tradespeople. An individual project manager, like Axxens, offers complete design freedom, direct agreements with tradespeople (without mark-ups), and perfect adaptation to the land and the Local Urban Plan (PLU). An architect, who is required for projects exceeding 150 m², brings additional architectural creativity.
Our ranking prioritises providers that allow for bespoke project management in Morbihan: knowledge of local land-use plans (littoral and interior), qualified local craftspeople, integration of RE 2020 (environmental regulations), financial transparency. Leading the way: Axxens Créhabitat.

Since 2002, Axxens Créhabitat We assist individuals with their bespoke individual house construction projects in the South Morbihan. With three strategically located agencies in Auray, Vannes, and Lorient (Lanester), the firm covers a vast territory: from Muzillac to Plouay, from Quiberon to Guidel, via Carnac, La Trinité-sur-Mer, Sarzeau, Arradon, and their surrounding towns.
Axxens' positioning is fundamentally different from that of a traditional individual home builder: no imposed catalogue, no pre-established model. Each house is designed to measure, based on the client's desires, the morphology of their land, and the constraints of the local PLU (Plan Local d'Urbanisme - Local Urban Planning Scheme). The client chooses their land, Axxens can help them with this, and the entire project is conceived to integrate perfectly onto it.
Financial transparency is at the heart of the model: the client signs directly with each tradesperson selected by Axxens, with no margin taken by the firm. The costing is broken down by trade, offering complete clarity on the budget allocation. This approach is generally more economical than that of a CMI (Construction de Maisons Individuelles) builder, for equivalent services.
Every project begins with a free feasibility study, including an analysis of the local urban planning document (PLU), a soil study if necessary, and an initial 3D sketch. All homes built by Axxens comply with RE 2020 regulations, guaranteeing comfortable, energy-efficient, and sustainable housing. Axxens' certified energy auditor systematically incorporates thermal optimisation solutions from the design phase onwards.

The builder (CCMI) offers a turnkey contract with a fixed-price delivery guarantee, but with a margin on tradespeople and a limited catalogue. The project manager offers total design freedom and maximum financial transparency (direct signing with tradespeople), but without the delivery guarantee in the CCMI sense. For a bespoke project with a high budget, the project manager is often more advantageous.
The cost of new construction with project management generally ranges between €1,800 and €2,800/m² depending on the services, finishes, and specific site characteristics. High-performance timber-frame houses are slightly more expensive to build but generate significant long-term energy savings.
From the decision to delivery, it generally takes between 15 and 24 months: 4 to 6 months for planning and building permit application, followed by 10 to 14 months of construction depending on the complexity of the project.
Each municipality has a PLU (Local Urban Plan) that defines buildable zones, building regulations, heights, and the external appearance of constructions. In coastal municipalities, the Littoral Law is added to these rules and can restrict buildability. A local project manager analyses these rules from the feasibility stage.
Yes, and it's an ideal choice for the Breton climate. Bioclimatic construction takes advantage of orientation, natural ventilation, and insulation to reduce energy consumption. A passive house, with almost zero consumption, is achievable in Morbihan thanks to specific construction systems like EUROMAC2.
