Building and renovating in Sillingy: a fast-growing municipality at the foot of the Mandallaz

Sillingy occupies a strategic position north-west of Annecy, along the route towards Frangy and the Val des Usses, at the foot of the Mandallaz massif. A quarter of an hour from central Annecy while keeping a real village character, the municipality has attracted many households looking for space over the past twenty years: its population has grown strongly, driven by housing estates, recent developments around the village centre and the business park that has grown up at the entrance to the municipality, continuous with La Balme-de-Sillingy.

Sillingy's buildings tell this story in successive layers: Savoyard farmhouses and village houses in the historic hamlets, detached houses from the 1980s to 2000s on the estates, contemporary builds on the last available plots. The result is very varied demand for work — building a house on a gently sloping plot, extending a house that has become too small, fully renovating an older house that has just been bought, or converting a farmhouse to give it a second life. All projects that call for real design know-how and rigorous management.

That is the role of the project manager: studying feasibility, designing the project, obtaining approvals, consulting and coordinating the trades, and keeping to the budget and schedule through to handover of the keys. From our office in Aix-les-Bains, we regularly work in Sillingy and the neighbouring municipalities: La Balme-de-Sillingy, Poisy, Épagny-Metz-Tessy, Chavanod and Annecy.

House renovation, extensions and farmhouse conversion in Sillingy

Renovating detached houses is the most frequent request in the municipality. Many houses built between 1980 and 2000 on Sillingy's estates are now showing their age: dated partitioning, closed-off kitchen, single glazing or worn windows, inadequate insulation, electric or oil heating at the end of its life. We rethink these houses as a whole — opening up living spaces, creating a master suite, completely renewing services, insulation and switching heating system — and manage all the trades through to handover.

Extensions and adding a storey meet the need for space of families who want to stay in Sillingy rather than move. A timber frame or masonry extension to enlarge the living area, a new floor above a garage, a partial roof raise: we study what the zoning regulations allow on your plot — building footprint, height, distances to boundaries — before drawing, then submit the prior declaration (déclaration préalable) or building permit application and carry out the works as general contractor.

Finally, farmhouse conversion is one of the municipality's finest opportunities. The hamlets of Sillingy retain Savoyard buildings with generous volumes — barn, cowshed, hayloft — that lend themselves remarkably well to contemporary living. Structural and roof timber survey, high-performance insulation that respects the old building, new openings, mezzanines under the roof trusses: as an RGE-certified company, we carry out these complete conversions, combining original character with energy performance.

Architect, project manager and RGE general contractor: a single point of contact in Sillingy

What sets Atelier NovAlp apart is bringing three professions under the same roof: architect, project manager and RGE-certified general contractor. You no longer have to get a designer, a design office and a dozen or so tradespeople who don't know each other talking: a single point of contact designs, prices, obtains the approvals and builds. This turnkey organisation eliminates the blurred boundaries between parties, which are the leading cause of delays, cost overruns and remedial work on private clients' projects.

On the planning side, Sillingy belongs to the Grand Annecy conurbation and its local plan (PLU) clearly distinguishes the village centre, the old hamlets, the residential areas and the surroundings of the RD 1508, as well as the agricultural and natural areas of the Mandallaz. Heights, building footprint, appearance of roofs and façades, rainwater management, landscape requirements on sloping or highly visible plots: we analyse the regulations applicable to your plot before putting pencil to paper, and submit applications that comply from the first review.

Our RGE CertiRénov certification no. CR-2026-73-0095 (comprehensive renovation offer, issued by Qualitel Certification) makes your energy renovation works eligible for grants: MaPrimeRénov', energy savings certificates (CEE) and local schemes. Insulation, windows and doors, heat pump, ventilation: we calculate the real remaining cost and build the grants into the financing plan.

Frequently asked questions — Sillingy

Do I need an architect to build or extend a house in Sillingy?
For a private individual in Sillingy, using an architect registered with the Ordre des architectes is only mandatory if the floor area of the building exceeds 150 m², or if an extension takes the total floor area above that threshold. Below it, a project manager can design the plans, submit the prior declaration (déclaration préalable) or building permit application, obtain quotes and supervise the works through to handover. Atelier NovAlp brings architect and project manager together in-house: we adapt the set-up to your project, whether it is extending a detached house or building new on the slopes of the Mandallaz.
What budget should I plan to renovate a house in Sillingy?
As a guide, in the Annecy area: a refresh (painting, flooring, kitchen, bathroom) costs €700 to €1,000/m²; a full renovation of a 1980s-90s detached house with new electrics, plumbing and insulation starts at around €1,200 to €1,500/m²; the major conversion of an old farmhouse, with structural and roof timber repairs, often exceeds €2,000/m². As every property is different, we carry out a free preliminary study with a site visit in Sillingy to frame the budget before any commitment.
What planning rules apply in Sillingy?
Sillingy is part of the Grand Annecy conurbation and its territory is covered by a local plan (PLU) that distinguishes the village centre, the old hamlets, the residential areas and the business parks along the RD 1508, as well as the agricultural and natural areas of the Mandallaz massif. Depending on the zone, the rules on height, building footprint, the appearance of roofs and façades or parking vary, and some sloping or highly visible sectors are subject to landscape requirements. We systematically check the regulations applicable to your plot before drawing, for an application that complies from the first submission.
Can a farmhouse or barn be converted in Sillingy?
Yes, subject to conditions. The hamlets of Sillingy still have fine Savoyard farmhouses whose volumes lend themselves very well to contemporary living. If the building is in an agricultural or natural zone, converting it into a home requires it to be identified in the local plan (PLU) as eligible for a change of use; in an urban zone, a building permit is generally enough as long as the structure allows it. We handle the structural survey, the design, the applications and the works: roof structure repairs, high-performance insulation, new openings and complete reconfiguration of the volumes.
Do you work in Sillingy and neighbouring municipalities?
Yes. From our office in Aix-les-Bains, we work in Sillingy and the neighbouring municipalities: La Balme-de-Sillingy, Poisy, Épagny-Metz-Tessy, Chavanod and Annecy. Our services cover house construction, extensions and adding a storey, full renovation of detached houses, farmhouse conversion and RGE energy renovation eligible for MaPrimeRénov'.
