Project manager & renovation in Bourdeau.

Bourdeau is one of the smallest and most secluded villages around Lac du Bourget. Clinging to the foot of the Dent du Chat on the west shore, it overlooks the largest natural lake in France and faces Aix-les-Bains, separated from it only by the water. Its Château de Bourdeau, its discreet harbour and above all its exceptional views over the lake and the Bauges have made it a prized location, where land is extremely scarce and panoramic villas are highly sought after.

This scarcity makes Bourdeau a market of its own: there is almost no new building, and most projects involve renovating, extending or rebuilding an existing villa to make the most of the view and the sunset over the water. The housing consists of fine detached houses terraced up the hillside, many dating from past decades and well worth modernising: reworked layouts, large glazed openings facing the lake, insulation and comfort brought up to date.

Two constraints shape every project here. First the Loi Littoral, which applies to this lakeside town and strictly limits building on the shores; then the sloping plot, almost universal on this hillside. That is precisely the role of the project manager: carrying your project from start to finish, securing the budget and schedule, and turning these constraints into assets. From our office in Aix-les-Bains, just 15 minutes away directly opposite on the other shore, we know this area and its immediate neighbours inside out (Le Bourget-du-Lac, Aix-les-Bains, La Chapelle-du-Mont-du-Chat, Tresserve).

Lake-view villa renovation is the most requested service in Bourdeau. On the hillside, many houses deserve a complete upgrade to showcase their greatest asset, the panorama: opening living spaces towards the lake, creating wide glazed openings and terraces facing Aix, upgrading insulation and heating, modernising bathrooms and finishes. We design these projects to measure, paying close attention to orientation, views over the water and the evening light, and manage all the trades through to handover.

Extending and building on a sloping plot requires real technical expertise, which is essential on this hillside. Positioning according to the gradient and the view, split-level houses that follow the terrain, soil survey, retaining structures, access and run-off management: every parameter must be anticipated at the design stage. Handled well, the slope becomes an asset — it opens up the view, structures the volumes and allows generous living spaces opening onto the lake.

Finally, energy renovation naturally complements these projects. Façade and roof insulation, replacing the heating system, new high-performance large glazing: this work brings lasting improvements to comfort and property value, and is eligible for public grants. As an RGE-certified company, we support each owner with the technical set-up and management of these works, in compliance with the Loi Littoral.

Atelier NovAlp's strength is bringing three professions together under one roof: architect, project manager and RGE-certified general contractor. In practice, you no longer have to coordinate an architect, an engineering firm, a project manager and a dozen tradespeople yourself: a single point of contact carries your project from the first sketch to handing over the keys. This turnkey approach removes the grey areas between the parties involved — which is where most delays, cost overruns and defects arise — a real advantage when the site is on a steep lakeside slope.

Depending on the nature of the project, we adapt the contractual set-up: an architect's assignment for a new build or a large extension, project management for a renovation with separate trade contracts, or general contracting with a commitment to results for a project on a controlled budget. In Bourdeau, a lakeside town subject to the Loi Littoral, we always check whether the plot can be built on and review the local plan (PLU) regulations — coastal strip, continuity of development, heights, building footprint, handling of the slope — before drawing, so the application is compliant on first submission.

Our RGE CertiRénov no. CR-2026-73-0095 certification (comprehensive renovation offer, issued by Qualitel Certification) also gives you access to grant schemes: MaPrimeRénov', Energy Savings Certificates (CEE) and local grants. We calculate your real out-of-pocket cost and build these subsidies into your renovation's financing plan. Discover all our services or our page dedicated to Aix-les-Bains.
