Renovating in Mouxy: the slopes of Mont Revard, five minutes from our office

Mouxy is terraced across the hillsides immediately east of Aix-les-Bains, at the foot of the Revard massif, in the Grand Lac conurbation. Between the old village, its hamlets and its residential neighbourhoods, the commune has remained residential and green while enjoying direct proximity to Aix town centre, the station and the thermal baths. Many plots enjoy a west-facing aspect with views of Lac du Bourget and the Dent du Chat — a rare asset that explains the area's lasting appeal to families.

The building stock tells this story: old farmhouses and village houses in the heart of the village, 1970s to 1990s houses in housing estates, more recent villas on the heights. Many of these homes are now reaching the age for major works: full renovation, energy upgrades, reconfiguring spaces, extensions or adding a storey to house a growing family — without giving up a plot you would never find anywhere else. The few plots still available call for new builds that sit well on the slope.

This is where geography works in your favour: our office is at 198 Avenue du Grand Port in Aix-les-Bains, just five minutes' drive from Mouxy. Being this close makes all the difference on a project — very frequent visits, immediate response if anything unexpected comes up, meetings that are easy to schedule, local trades who already know the area. Few project managers can follow your works this closely.

Renovation, extensions, adding a storey and new builds in Mouxy

House renovation is the most common request in Mouxy. On 1970s to 1990s houses, everything often happens at once: opening the kitchen onto the living room, creating large windows facing the lake, redoing the electrics and plumbing, insulating walls and roof, replacing an ageing heating system with an efficient solution. We design these projects as a whole — plans, budget, permits — then carry out the works with our own teams, through to handover.

Extensions and adding a storey are particularly worthwhile in the commune: sloping plots offer possibilities for extending downhill or at lower-ground level, and one extra floor is sometimes enough to open up a clear view of Lac du Bourget. We study the existing structure, check the height and footprint rules applicable to your zone, then design a volume that naturally extends the house — timber frame, masonry or a mix depending on the context. For characterful properties in the old village, we take particular care over integration.

Finally, energy renovation and new builds complete our activity in Mouxy. External wall insulation, windows and doors, ventilation, heat pump: as an RGE-certified company, we design coherent packages of works that are eligible for financial aid. And for a new-build project on one of the last building plots, we take on the full commission, from site plan to the final brushstroke.

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

Renovating or extending a house usually involves an architect, an engineering firm, a project manager and a dozen trades — all of whom you have to get talking to each other. Atelier NovAlp brings these three professions together in-house: architect, project manager and RGE-certified general contractor. For your project in Mouxy, this means a single turnkey point of contact, responsible for design, budget, schedule and execution, from the first sketch to handing over the keys. The grey areas between parties — where delays, cost overruns and defects arise — disappear.

On the regulatory side, Mouxy is part of the Grand Lac conurbation and its planning document closely regulates the hillsides: heights, footprint, appearance of facades and roofs, management of slopes and access, sectors close to farmland or woodland. Before drawing, we always check the regulations for the zone concerned, then put together the application — prior declaration (déclaration préalable) or building permit — for a compliant submission first time at Mouxy town hall.

Our RGE CertiRénov certification no. CR-2026-73-0095 (Comprehensive renovation offer, issued by Qualitel Certification) gives your project access to financial aid: MaPrimeRénov', Energy Savings Certificates (CEE), éco-PTZ and reduced VAT. We include these schemes from the pricing stage to give you your actual out-of-pocket cost, not a theoretical quote. Explore all our services or our page dedicated to Aix-les-Bains.

Frequently asked questions — Mouxy

Do you need a building permit for an extension or an added storey in Mouxy?
In Mouxy, an extension creating between 5 and 40 m² of floor area in an urban zone generally requires a prior declaration (déclaration préalable); above 40 m², or if the total floor area of the house exceeds 150 m² after the works, a building permit is required — and, in the latter case, using an architect is mandatory. Adding a storey follows the same thresholds, with particular attention to height rules and how the building sits on the slope. Atelier NovAlp puts together the entire planning application, from plans to drawings, and submits it for you at Mouxy town hall.
What budget should you plan to renovate a house in Mouxy?
For a house from the 1970s to 1990s, of which there are many in Mouxy's residential neighbourhoods, allow as a guide €400 to €800/m² for a refresh (flooring, painting, bathroom), €1,000 to €1,500/m² for a full renovation including electrics, plumbing and insulation, and over €1,800/m² for major restructuring with changes to the layout. An extension generally costs €2,000 to €3,000/m² depending on the construction method. We provide a precise estimate after a site visit — easy to arrange, as our office is five minutes away.
Can adding a storey give you a view of Lac du Bourget in Mouxy?
Often, yes. Mouxy is terraced across the hillsides at the foot of Mont Revard, and one extra floor is sometimes enough to open up a clear view of Lac du Bourget and the Dent du Chat. Technically, it all depends on the capacity of the existing structure to take the loads and on the height rules set by the planning document for your zone. We carry out a full feasibility study — structure, planning, budget — before any commitment, to tell you clearly whether the project is viable and at what cost.
What financial aid is available for an energy renovation in Mouxy?
Homeowners in Mouxy have access to MaPrimeRénov' (including the major renovation pathway), Energy Savings Certificates (CEE), the éco-PTZ interest-free loan and the reduced 5.5% VAT rate on eligible works. An essential condition: the works must be entrusted to an RGE-certified company. Atelier NovAlp holds RGE CertiRénov certification no. CR-2026-73-0095 (Comprehensive renovation offer, issued by Qualitel Certification): we design the programme of works, calculate your actual out-of-pocket cost after grants and carry out the project from start to finish.
Can you get to Mouxy quickly from Aix-les-Bains?
Yes — Mouxy is one of our closest areas of work. Our office at 198 Avenue du Grand Port in Aix-les-Bains is about five minutes' drive from Mouxy town hall. Being this close allows very frequent site visits, meetings that are easy to schedule and fast response if anything unexpected comes up.
