Building a chalet
in Haute-Savoie.

Haute-Savoie is home to some of the most dynamic property markets in the French Alps. The proximity of Geneva, the prestige of the ski resorts (Chamonix, Megève, Morzine, Les Gets) and the appeal of Lake Annecy attract a demanding international clientele. Building land there is scarce and expensive, local plans are highly prescriptive, and expectations for build quality are high.

In this context, the price per m² of a new chalet in Haute-Savoie is well above the national average. The gap is explained by three main factors: the cost of land (often 30 to 50% of the total budget in ski resorts), the technical requirements linked to altitude and climate, and the level of finish expected in a market where international competition drives quality upwards.

Atelier NovAlp works across the whole department, from the Arve valley to the Chablais ski resorts, from the Aravis range to the Annecy basin. Our role as project manager: supporting you from the search for land to handing over the keys, with a controlled budget and a realistic schedule. Our knowledge of the area and the local trades lets us optimise every cost item without sacrificing quality.

A price per m² quoted by a builder almost never covers the real cost of the operation. That is not dishonesty, it is a convention of the trade: the figure covers the building, not the project. Here is what is systematically left aside, and has to be added before comparing two offers.

The plot and what it imposes. Purchase, boundary survey, ground survey, earthworks, retaining structures if the plot slopes — and in Haute-Savoie it often does. Access counts too: a plot where the crane cannot stand, or that a concrete mixer cannot reach, changes the construction method and therefore the price.

Service connections. Water, electricity, drainage, telecoms: the length of the trenches is paid for by the metre. Where there is no mains drainage, the treatment system to be installed is an item in its own right, sized after the ground survey.

Taxes and ancillary costs. Development tax, structural damage insurance, connection to public networks, design and supervision fees. None of these lines appear in a price per m², and they are all payable.

What the price per m² hides. The level of finish, above all. Between a chalet handed over with basic equipment and the same chalet with bespoke timber-aluminium windows, solid timber flooring, a wood burner and a fitted kitchen, the gap runs into hundreds of euros per square metre — on the same plan and the same floor area.

That is why we never give a price before seeing the plot and settling the level of specification. The quotation we hand you is broken down item by item: you can see what is included, and above all what is not.

The choice between a ski resort and the valley determines a significant share of the total budget. In ski resorts (Chamonix, Megève, Morzine, Les Gets, La Clusaz), the plot often accounts for 40 to 60% of the overall budget: building plots sell for €800 to €2,000/m², and construction itself costs 20 to 40% more than on the valley floor because of access, logistics and architectural requirements.

In the valley (Sallanches, Cluses, Bonneville, Thônes, La Roche-sur-Foron), land is more affordable (€200 to €400/m²) and local plan constraints are less onerous. The construction budget stays at the lower end of the range (€2,500 to €3,500/m²). It is the preferred choice for families building a main residence who want a mountain setting without the resort premium.

The Annecy basin is an intermediate case: a tight land market (€500 to €900/m²) but easy access, plenty of tradespeople, and demand driven by cross-border workers commuting to Geneva. The municipalities on the lake's west shore (Sevrier, Saint-Jorioz, Duingt) and around the Semnoz offer exceptional views but land at a premium price.

RE2020 (France's 2020 environmental building regulations) imposes tougher requirements in climate zone H1c (altitude above 800 m), which covers most municipalities in Haute-Savoie. The carbon emission and energy performance thresholds are more ambitious than on the plains, which directly affects the construction budget.

In practice, RE2020 at altitude means: reinforced insulation (240 to 300 mm of wood fibre in walls, 350 to 400 mm in the roof), triple glazing throughout with thermally broken timber-aluminium frames, heat-recovery ventilation with a high-efficiency heat exchanger, and an airtightness test (target 0.4 m³/h.m²). The extra cost compared with the former RT2012 is estimated at 8 to 12%.

Timber — the dominant material in chalet building — nevertheless has a decisive advantage for RE2020: its bio-based carbon footprint more than offsets the emissions from the build. A chalet with a timber structure (frame or logs) meets the carbon thresholds more easily than a masonry building. We systematically favour local larch (Savoie, Haute-Savoie, Valais) and RGE certification to guarantee regulatory compliance and access to grants.

The plot and its servicing are the first variable cost item. A sloping plot (common in Haute-Savoie) requires substantial earthworks, and even retaining walls and special foundations (micropiles, ground beams). Connecting to utilities (water, electricity, drainage) costs €15,000 to €50,000 depending on the distance.

The structure and building envelope account for 35 to 45% of the construction budget. The choice between timber frame (fast, economical), stacked logs (authentic, more expensive) or post-and-beam (open volumes, long spans) has a significant impact on cost. The roofing (natural slate vs clay tiles vs steel sheeting) adds a difference of €80 to €200/m².

Interior finishes make the difference between a standard chalet and a prestige chalet. A quality fit-out (solid oak parquet, bespoke kitchen, natural stone bathrooms) represents 25 to 35% of the total budget. Home automation, a spa and wellness facilities (sauna, steam room, indoor pool) can add €50,000 to €200,000 to the budget.

Our approach as project manager: setting a realistic budget with you from the sketch stage, then sticking to it through rigorous costing of every trade and weekly site supervision. No unpleasant surprises: every item is priced, approved and monitored.
