Project management & renovation in Groisy.

Set on the plateau between Annecy and La Roche-sur-Foron, Groisy holds a strategic position on the Annecy-Geneva corridor. Its regional TER station, the nearby RD 1203 and quick access to both the Annecy area and the Geneva area make it one of the most attractive municipalities in northern Grand Annecy for families and cross-border commuters. The result: growing suburbanisation, a steadily rising population and a property market where older homes to renovate sit alongside building plots.

The built landscape of Groisy tells this story: a village centre clustered around the church, a constellation of hamlets — Le Plot, and many other scattered settlements across the hedged farmland — where fine Savoyard farmhouses are still waiting to be restored, and recent housing estates born of the land pressure along the Alpine corridor. Three types of project dominate: farmhouse renovation with barns converted into living space, new detached houses, and extensions to family homes that have become too small for growing families.

Each of these projects calls for method: survey of the existing building, design, planning applications, contractor tendering, coordination and handover. That is the job of the project manager. Atelier NovAlp works regularly in Groisy and the neighbouring towns — Charvonnex, Cuvat, Villaz, Pringy, Thorens-Glières — and carries your project from start to finish, protecting both your budget and your schedule.

Farmhouse renovation is the signature request in Groisy. These generously proportioned buildings — thick walls, imposing roof structures, adjoining barns — offer exceptional potential: converting the barn into a double-height living room, creating openings to bring in light, high-performance insulation that respects the old walls, and bringing all services fully up to standard. We design these refurbishments to preserve the Savoyard character of the building — roof pitches, timber cladding, surrounds — while giving it the comfort of a contemporary home.

New builds follow the village's population growth. On a plot in a housing estate or a separate plot in a hamlet, we design houses suited to the plateau's climate — an altitude of around 700 m, harsh winters — and compliant with local planning regulations: siting, orientation, managing the slope, RE2020 performance. As general contractor, we commit to a price and a timeframe, from the building permit to handing over the keys.

Finally, extensions and adding a storey meet the needs of owners of houses built between the 1980s and 2000s: an extra living room, a master suite, a garage converted into a studio. Combined with an RGE energy renovation — insulation, windows and doors, heat pump, ventilation —, these projects add lasting value to your property while cutting your bills, with the support of public grants.

Renovating a farmhouse or building in Groisy usually means coordinating an architect, an engineering firm and then a dozen or so tradespeople — each with their own quote, schedule and scope limits. Atelier NovAlp brings these three professions together under one roof: architect, project manager and RGE-certified general contractor. A single point of contact delivers your project turnkey, from the first sketch to handing over the keys, and removes the grey areas between parties — where delays, cost overruns and defects arise.

On the planning side, Groisy comes under Grand Annecy and its territory alternates between urban zones in the village centre, buildable hamlets and large protected agricultural or natural areas. Change of use of a barn, external appearance in areas of character, setbacks from roads, rainwater management: we check the zone regulations before putting pencil to paper and submit compliant applications at the first attempt — prior declaration (déclaration préalable) and building permit alike.

Our RGE CertiRénov no. CR-2026-73-0095 certification (comprehensive renovation offer, issued by Qualitel Certification) gives access to grants: MaPrimeRénov', Energy Savings Certificates (CEE) and local schemes. We calculate the real out-of-pocket cost and build these subsidies into the financing plan from the preliminary study onwards. Discover all our services or our page dedicated to Annecy.
