Le Bourget-du-Lac: building and renovating on the shores of France's largest natural lake

Set on the southern shore of Lac du Bourget, facing the silhouette of the Dent du Chat, Le Bourget-du-Lac has a wealth of assets: a marina and some of the most sought-after lakeshores in Savoie, a lively village centre around the priory, and above all the Savoie Technolac technology park, a centre of excellence for solar energy and a campus of Université Savoie Mont Blanc, which attracts engineers, researchers and start-ups every year. Part of the Grand Lac conurbation, the town is a quarter of an hour from Chambéry and ten minutes from Aix-les-Bains.

The built fabric reflects this appeal: contemporary villas near the shore, houses from the 1960s to 90s on the heights and along the plain, converted farmhouses on the hillside and recent new developments driven by Technolac's dynamism. The result: strong pressure on land and scarce building plots, further constrained by the Loi Littoral. For many homeowners in Le Bourget-du-Lac, the best move is no longer to relocate but to renovate, extend or add a storey to the existing house — provided the regulatory side is secured and the budget is kept under control.

That is exactly the role of the project manager: designing the project, obtaining consents, getting quotes from the trades, then managing the works through to handover. Atelier NovAlp is based in Aix-les-Bains, around ten minutes from Le Bourget-du-Lac: this immediate proximity means frequent site visits, maximum responsiveness if anything unexpected comes up and real knowledge of the area, from Bourdeau to Voglans via Viviers-du-Lac and La Motte-Servolex.

New builds, house renovation and extensions in Le Bourget-du-Lac

In new-build project management, we design new houses tailored to the site: oriented towards the lake or the Dent du Chat, compact high-performance volumes, durable materials and RE2020 compliance. In a town where building land is becoming scarce, every square metre counts: we optimise the siting with regard to the local plan (PLU) and the Loi Littoral, file the building permit, obtain quotes from the trades and manage the works through to handing over the keys, with the budget locked in from the design stage.

House renovation is the most frequent request in Le Bourget-du-Lac. Houses from the 1960s to 90s — very common between the village centre, the heights and the Voglans plain — often suffer from outdated insulation, compartmentalised layouts and energy-hungry heating systems. We restructure living spaces, open rooms to the outdoors, upgrade services, insulation and heating, and bring finishes up to the standard expected in this sought-after area. Flats in recent developments or co-ownership buildings near the marina receive the same care, from the initial survey to handover.

Finally, extensions and adding a storey respond to local pressure on land: extend rather than move. A flat-roofed extension or one set into the slope, a partial additional storey, converting a garage into living space, creating a master suite or a home office facing the lake: we first check what the rules allow on your plot — footprint, height, appearance, lakeshore requirements — then design a project that genuinely adds value to your property.

Loi Littoral, Grand Lac local plan: a single point of contact who knows the lake's rules

Building or extending in Le Bourget-du-Lac means dealing with a demanding regulatory framework. As Lac du Bourget exceeds 1,000 hectares, the town is a lakeshore municipality under the Loi Littoral: development must be contiguous, extension is limited in areas close to the shore, and the 100-metre strip cannot be built on outside built-up areas. These principles are layered on top of the town's local plan (PLU), drawn up with the Grand Lac conurbation, which sets building footprints, heights, façade appearance and the protection of views towards the lake and the Dent du Chat. A project that is legally ill-prepared means months lost: we analyse your plot's zoning before the first pencil stroke.

Our other strength is bringing three professions together under one roof: architect, project manager and RGE-certified general contractor. You no longer have to coordinate a designer, an engineering firm and a dozen tradespeople yourself: a single turnkey point of contact carries the project, from the initial survey to the handover report. Depending on the case, we act under an architect's commission, as a conventional project manager or as a general contractor with a commitment to results — the set-up adapts to the project, never the other way round.

Finally, our RGE CertiRénov no. CR-2026-73-0095 certification (whole-house renovation offer, issued by Qualitel Certification) gives entitlement to energy renovation grants: MaPrimeRénov', Energy Saving Certificates (CEE) and local schemes. Insulation, windows and doors, heat pumps, ventilation: we calculate the real remaining cost and build the subsidies into the financing plan.

Frequently asked questions — Le Bourget-du-Lac

Do you need a building permit for an extension in Le Bourget-du-Lac?
In Le Bourget-du-Lac, an extension with a footprint of 5 to 40 m² in an urban zone of the local plan (PLU) generally requires a prior declaration (déclaration préalable); beyond that, or if the total floor area of the house exceeds 150 m² after the works, a building permit is required and using an architect becomes mandatory. As the town lies on the shore of Lac du Bourget, the Loi Littoral (French coastal and lakeshore law) applies in addition to the PLU: depending on where the plot is located (areas close to the shore, the 100-metre strip outside built-up areas), the scope for extensions may be restricted. We check the exact zoning before sketching, then submit and follow the application through to approval.
Does the Loi Littoral apply to works in Le Bourget-du-Lac?
Yes. As Lac du Bourget is a body of water of more than 1,000 hectares, all the lakeside towns — including Le Bourget-du-Lac — are subject to the Loi Littoral. In practice: new buildings must be in continuity with existing built-up areas, areas close to the shore only allow limited extension of urban development, and the 100-metre strip cannot be built on outside already built-up zones. These rules combine with the town's local plan (PLU), managed by the Grand Lac conurbation. A renovation within the existing volumes, however, generally remains possible; we secure every project with a full regulatory analysis before any application is submitted.
What budget should you plan to renovate a house in Le Bourget-du-Lac?
The Le Bourget-du-Lac market is driven by the proximity of the lake and Savoie Technolac: properties sell at high prices and a quality renovation quickly adds value. As a guide: a refresh (paintwork, floors, kitchen, bathroom) costs €700 to €1,000/m²; a full renovation including new services and insulation starts at around €1,300/m²; a major renovation with restructuring or an extension often exceeds €1,800/m². A free preliminary study with a site visit — we are around ten minutes away from Aix-les-Bains — lets you set a reliable budget before making any commitment.
What grants are available for an energy renovation in Le Bourget-du-Lac?
As an RGE CertiRénov certified company (no. CR-2026-73-0095, Offre globale de rénovation, issued by Qualitel Certification), we give you access to MaPrimeRénov', Energy Savings Certificates (CEE) and any local grants. Wall and roof insulation, window and door replacement, heat pump, ventilation: we cost the works, estimate the grants available and build the real out-of-pocket amount into your financing plan. This is particularly relevant for the 1960s to 1990s houses in Le Bourget-du-Lac's residential areas, which are often energy-hungry.
