Project manager & renovation in Trévignin.

Trévignin is one of the most sought-after villages in the hills above Aix-les-Bains. Clinging to the Revard road, this hillside village overlooks the spa town and its slopes offer an open view over Lac du Bourget and the Dent du Chat. It has quality detached homes, a few fine renovated Savoyard farmhouses and plots still available higher up: a quiet, green and highly prized setting, just minutes from the shops and the station in Aix-les-Bains.

This privileged location makes Trévignin a buoyant area for construction, extensions and renovation. Many owners want to build a new house that makes the most of the view, enlarge a house that has become too small, or restructure an old farmhouse to bring it up to today's standards of comfort. Every project requires method: an accurate survey, a study of the slope, plans, submitting applications to the Grand Lac conurbation, coordination of the trades and rigorous site supervision.

That is precisely the role of the project manager: to carry your project from start to finish, protect your budget and schedule, and spare you from juggling a dozen different firms. Our office is based in Aix-les-Bains, only about ten minutes from Trévignin: we know this area inside out and work regularly in the village and its immediate neighbours (Pugny-Chatenod, Le Montcel, Mouxy, Grésy-sur-Aix).

Detached house construction is a key request in Trévignin. Higher up in the village, available plots almost always have a steep slope: building requires a soil survey, a suitable design (house over a buried basement, split levels, cantilevered terraces) and careful management of access, earthworks and retaining structures. We design each house to capture the view over the lake and the wider landscape rather than suffer the topography, and we price the specific items from the outline design stage.

Extensions and renovation of detached houses concern the quality residential fabric that makes up the village. Enlarging to gain a room or a master suite, adding a storey, opening up living spaces, creating large windows facing the valley, upgrading insulation and heating: we work on houses from the 1970s to the 2000s as well as more recent properties in need of modernisation. The challenge is always to connect new and existing seamlessly.

Finally, renovating farmhouses and old buildings requires particular attention to the character of Savoyard architecture: volumes, materials, roofs, openings. These projects, often major, are frequently eligible for energy renovation grants. As an RGE-certified company, we support owners with the technical set-up and full management, including insulation and heating replacement, where the Grand Lac local plan (PLU) allows.

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 or so tradespeople yourself: a single point of contact carries your project, from the first sketch to the handover of the keys. This turnkey approach removes the grey areas between the parties involved — which is where most delays, cost overruns and defects arise.

Depending on the nature of the project, we adapt the arrangement: 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. As all planning applications in Trévignin fall under the Grand Lac local plan (PLU), we always check the zone regulations — heights, building footprint, facade colours, roof appearance, siting and handling of the slope — before drawing, so the application is compliant from the first submission.

Our RGE CertiRénov certification no. CR-2026-73-0095 (Offre globale de rénovation, 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 project's financing plan. Discover all of our services or our page dedicated to Aix-les-Bains.
