Project manager & renovation in Tresserve.

Perched between Aix-les-Bains and the east shore of Lac du Bourget, Tresserve enjoys a position envied by the whole Grand Lac area. Its hill — the famous “poets' hill” dear to Lamartine — attracted a wealthy clientele as early as the Belle Époque, who built character villas, bourgeois residences and wooded estates facing the lake. Even today, the town remains one of the most sought-after residential addresses in Savoie: generous plots, absolute calm and a sweeping view over the largest natural lake in France, a stone's throw from the thermal baths and Aix station.

This heritage has a downside: much of Tresserve's housing stock predates the first thermal regulations. 1900s villas with superb but energy-hungry volumes, family homes from the 1960s to 90s with compartmentalised layouts, properties whose lake-view potential remains untapped: local demand focuses overwhelmingly on character villa renovation, extensions and energy renovation of older houses. And as buildable land has become extremely rare, making the most of what already exists is almost always the best — and only — option.

These projects demand method: an accurate survey, design that respects the building, a solid planning application and careful coordination of the trades. That is the job of the project manager — and in Tresserve, we are on home ground. Our office is located at 198 Avenue du Grand Port in Aix-les-Bains, five minutes from the hill: impromptu site meetings, same-day feasibility visits, close supervision from the first pencil stroke to handing over the keys.

Character villa renovation is Tresserve's signature. On the hill, Belle Époque residences and bourgeois houses call for a balancing act: restoring what gives them their soul — mouldings, ironwork, original joinery, ceiling heights — while bringing in today's comfort. Complete renewal of services, high-performance yet invisible insulation, contemporary bathrooms, reorganised volumes to open living spaces towards the lake: we design each project to measure and manage all the trades through to handover.

Extensions and adding a storey respond to a Tresserve reality: there is no land left, so people extend. Timber or masonry extensions into the slope, winter conservatories facing the lake, adding a storey to a 1970s house, converting a garage or semi-basement level into living space: so many ways to gain square metres without leaving the hill. We provide the architectural design, the permit application and the construction, paying particular attention to the landscape integration the area requires.

Finally, energy renovation of older houses has become essential: many Tresserve properties have E, F or G ratings that weigh on comfort as well as value. Wall and loft insulation, window replacement, heat pumps, ventilation: as an RGE-certified company, we design coherent packages of work, eligible for grants, that turn an energy-hungry villa into an efficient home — without betraying its character.

Atelier NovAlp's strength is bringing three disciplines together under one roof: architect, project manager and RGE-certified general contractor. For a character villa in Tresserve, this changes everything: you no longer coordinate an architect, an engineering office, a project manager and a dozen or so tradespeople yourself — a single point of contact carries the 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.

Tresserve's regulatory framework deserves this rigour. As a town on the shore of Lac du Bourget, Tresserve is subject to the Loi Littoral: extensions contiguous with existing development, a protected 100-metre strip along the lake shore, classified woodland on the hill. On top of this comes the local plan (PLU) and its own requirements — heights, ground coverage, facade appearance, sightlines with the lake. We systematically check zoning and regulatory feasibility before drawing anything, so that the application is accepted at the 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.
