The High Cost of New Builds: How Material Price Surges Are Reshaping French Alpine Construction

Property development in the French Alps in 2026 looks meaningfully different to the same market five years ago. The combined impact of the 2022–2023 energy shock, sustained materials inflation, labour cost pressure, rising environmental standards, and a wave of regulatory change under the RE2020 building code has pushed new-build construction costs to levels that would have looked unthinkable before the pandemic. For buyers looking at new-build ski apartments in Haute-Savoie, Savoie or the broader Alps, understanding this cost landscape is essential — because it drives the pricing you see on marketing brochures, the specification you actually get, and the timeline a developer can credibly commit to.

This guide is written for serious buyers rather than market commentators. We’ll walk through the material and labour cost increases that have reshaped the Alpine construction economics since 2021, the specific items that have moved most sharply, how developers have adapted their product in response, what the cost base means for price per square metre at the point of sale, and the critical 20% VAT reclaim mechanism that materially changes the effective purchase price for investor buyers. Along the way we’ll flag the construction red flags worth asking about before reserving a VEFA, because not all 2026 new-build projects are equally robust — some developers have absorbed the cost pressure and delivered; others have struggled, cut specifications, missed deadlines, or been forced to renegotiate prices with early reservers.

The headline for buyers is that new-build prices in 2026 are roughly 15–25% higher than they were in 2020 for equivalent specification at equivalent altitude in equivalent resorts. That sounds alarming until you consider the three offsetting factors that make the new-build proposition still more attractive than resale for many investors: the 20% VAT reclaim on managed rentals, the 2–4% notary fees versus 7–9% on resale, and the fact that post-RE2020 new-builds are significantly more energy-efficient and therefore less exposed to the DPE reform that has begun penalising poor-rated resale stock. We’ll cover each of these offsetting factors in detail.

The construction cost story is more complex than the simple ‘material prices doubled’ headline that has dominated the English-language property press. The French national construction cost index (ICC) published quarterly by INSEE tracks actual measured cost inflation for new residential construction, and the data tells a nuanced story: the index rose approximately 22% from Q1 2020 to Q4 2024, with the bulk of the increase concentrated in 2021–2022 (post-pandemic supply chain disruption plus energy shock) and a meaningful flattening through 2023–2024 as materials supply normalised and energy prices fell back from their 2022 peaks.

Within that headline figure, specific items moved very differently. Timber and softwood framing materials saw the sharpest price spikes in 2021–2022, in some cases doubling in six months as global demand recovery collided with disrupted supply chains — but softwood prices have substantially normalised since, and the 2025 price level is roughly 25–30% above the 2019 baseline rather than the 100% peak seen mid-cycle. Steel and structural reinforcement saw similar volatility, peaked lower than timber, and normalised faster. Cement and concrete rose more steadily (roughly 15–20% over five years) and have remained elevated because of the underlying energy intensity of the clinker production process.

Labour costs have been the underappreciated driver. The French construction industry faced sustained skilled-labour shortages through 2022–2024 and wages in the French building trades rose roughly 15% over the period, with the most acute pressure on specialised trades like stonemasons, timber framers, and the HVAC technicians required for the heat pump installations mandated under RE2020. For a French Alpine new-build, where the altitude, winter weather and tight construction windows require premium contractors with local experience, the labour component of total cost has risen meaningfully as a share of the total.

The final driver is regulatory cost. The RE2020 environmental regulation, which took effect in January 2022 and progressively tightened through 2025, requires significantly better thermal performance, carbon-footprint accounting of construction materials, and the near-elimination of gas heating in new residential construction. These requirements deliver real benefits — post-RE2020 apartments have much lower running costs and are better protected against the 2026 DPE reform — but they add roughly 8–12% to the gross construction cost of a Haute-Savoie Alpine apartment compared to the equivalent project built to pre-2022 standards.

Faced with this cost environment, the best developers in the French Alps have adapted in three ways. First, price discipline at the brochure stage — the strongest operators have been willing to raise the advertised price per square metre to reflect the true cost base, accepting a slower sales pace rather than absorbing costs and later cutting specifications or quality. Buyers should view willingness to price honestly as a signal of operator strength, not weakness, because the alternative is almost always a project that runs into trouble during construction.

Second, specification adaptation — keeping the headline brand positioning (prime kitchens, proper bathrooms, fitted wardrobes) while quietly adjusting less-visible specifications (fewer premium fittings, slightly lower-grade flooring in secondary rooms, simpler window treatments). This is a legitimate response to cost pressure if executed honestly, but some operators have crossed the line from specification adaptation into misleading specification cuts — so it is worth asking for a detailed finishing schedule (descriptif de finitions) before reserving a VEFA and comparing it against the project’s marketing brochure.

Third, project rephasing — delivering projects in phases, with later phases priced higher to reflect ongoing cost inflation. This is relatively common for larger developments and is generally honest if communicated clearly to early buyers. The red flag is when a developer has priced a phase 1 aggressively to build momentum and then comes back to reservers with ‘unforeseen cost pressures’ requiring a renegotiation — this has happened on a handful of Alpine projects in 2023–2024 and is a warning sign for the operator’s broader financial discipline. Our buying process guide covers the contractual protections that apply to VEFA purchases and when they bite.

Translating the cost base into end-buyer pricing, the ranges for 2025–2026 new-build VEFA in the French Alps are well established. At the premium end, Courchevel 1850 and Val d’Isère central new-build is trading at €18,000–25,000+ per square metre for exceptional addresses. Megève centre at €12,000–16,000/m². Chamonix centre at €11,000–14,000/m². Val Thorens, Tignes Le Lac, Méribel at €10,000–14,000/m². The prestige cohort sits above €10,000/m² almost without exception now.

At the mid-market, resorts like Les Gets, Morzine, Saint-Gervais, La Plagne 1800, Arc 1800 and Samoëns trade new-build at €7,000–10,000/m² for the central addresses and €5,500–8,000/m² for lightly-off-centre or lower-altitude product. Value plays like Bourg-Saint-Maurice, Thollon-les-Mémises, Les Contamines and some of the Haute-Savoie lakeside villages still offer new-build below €7,000/m² and in some cases below €5,500/m² for the better-priced projects.

These ranges reflect current 2025 launch pricing. Buyers reviewing older marketing material should assume 10–15% price escalation from 2023 brochures to 2025 brochures in the mid-market, and slightly more at the premium end. When comparing resale apartments to new-build at similar headline prices, remember to factor in the difference in notary fees (2–4% for VEFA versus 7–9% for resale), the VAT reclaim opportunity on VEFA rental-programme purchases, and the significantly different running cost profile between a post-RE2020 new-build and a 1970s ski-resort apartment.

The single most important offsetting factor in the new-build value proposition is the French 20% VAT reclaim for investor buyers. Under the furnished rental (LMNP) scheme combined with a classified managed rental programme, a VEFA purchase qualifies for recovery of the 20% French VAT included in the gross purchase price, provided the property is entered into a professional rental programme with a minimum nine-year commitment. The VAT is refunded by the French tax authorities post-completion, either directly or by offset against rental income, and the effect on the economics is substantial.

On a €600,000 gross-price VEFA apartment, the 20% VAT component is €100,000. Recovering that VAT effectively reduces the net purchase price to €500,000, which transforms the rental yield calculation. A €600,000 apartment generating €22,000 of net annual rent is a 3.7% gross yield; the same property at a €500,000 net cost is a 4.4% gross yield. On a property held for fifteen years, that 70 basis-point improvement compounds meaningfully, and it is the single strongest argument for new-build over resale for any investor buyer who is otherwise indifferent between the two.

The VAT reclaim comes with specific conditions: the property must be furnished, it must be in a classified managed rental programme (there are rules about how long the property can be retained for personal use — typically capped at six weeks per year for full VAT recovery), the rental programme operator must be approved, and the nine-year commitment is enforceable. Breaking the commitment early triggers a pro-rata VAT clawback. These rules are well-established and Domosno’s buying team handles the VAT reclaim process for every investor client as a standard part of the service. Our buying process guide explains the mechanics in detail and our French mortgage calculator models the post-VAT economics.

The second offsetting factor is the energy performance advantage. Post-RE2020 new-build apartments achieve DPE ratings of A or B almost by default thanks to mandatory high insulation standards, mechanical ventilation with heat recovery (VMC double flux), triple glazing, and heat pump heating rather than direct electric radiators. By contrast, the resale stock that buyers are often comparing new-build against includes substantial 1960s–1990s inventory with DPE ratings of D, E or worse.

This matters in 2026 for two reasons. First, running costs. A post-RE2020 apartment at 1,500m altitude uses roughly one-third to one-half the heating energy of a 1980s equivalent apartment in the same resort, and the difference is tangible on the monthly bill — particularly now that electricity and gas remain materially above pre-2022 pricing. A buyer who expects to use the property for 8–12 weeks per year will notice the difference.

Second, the 2026 DPE reform — covered in our dedicated DPE reform article — changes the coefficient for electric heating in a way that will improve ratings for electrically-heated apartments but not change the underlying reality that poorly-insulated resale stock still loses heat fast and still has high consumption whether measured in the old or new DPE framework. Regulatory pressure on F and G rated rental stock is continuing to tighten under successive French laws (the Climate and Resilience Law of 2021 and subsequent implementing decrees), and post-RE2020 new-builds are fully exempt from these pressures for the foreseeable future. That is a meaningful risk reduction for any investor planning to hold the property for fifteen years or more.

Given the cost pressure environment and the variance in operator quality, serious buyers should ask five specific questions before signing a VEFA reservation contract on a 2026-delivery project. First: what is the developer’s track record on recent completions? Ask for the names of recent (2022–2025) projects the same operator has delivered, look them up, and ideally visit one. Operators with no recent delivery history or with projects running visibly behind schedule are higher-risk propositions regardless of how attractive the brochure looks.

Second: what is the detailed finishing schedule (descriptif de finitions)? This is the binding list of specifications that form part of the VEFA contract and it should specify make, model, and grade for kitchens, bathrooms, flooring, doors, windows and fittings. If the operator is reluctant to provide a detailed descriptif at the reservation stage, take that as a warning. Third: what are the independent third-party guarantees? French VEFA law requires a Garantie Financière d’Achèvement (GFA) from a regulated French bank or insurer covering completion even if the developer fails — ask to see the GFA certificate, not just a verbal assurance.

Fourth: is the rental programme operator separate from the developer? A credible VAT-reclaim programme is operated by an established rental management company, often separately from the developer itself. Programmes where the developer is also the rental operator, and particularly programmes where the developer promises a fixed rental guarantee, should be scrutinised with extra care — some of the most significant buyer losses in the 2010s came from developer-promised fixed guarantees that later collapsed. Fifth: what is the honest delivery timeline, and what are the contractual penalties for delay? Most VEFA contracts include some form of delay penalty, but the enforcement varies. The Domosno team reviews all these elements on every project we sell, and we are deliberate about which operators we work with.

Looking ahead into 2026–2027, the consensus among the developers Domosno works with is that material cost pressure has largely stabilised but will not meaningfully reverse. The 2022 peak prices are not coming back, and the 2020 cost base is gone for good — buyers should plan for a new-build cost environment that is 15–25% above the pre-pandemic baseline and budget accordingly. The labour cost story is similarly durable; the French construction industry’s skilled-trade shortages are structural and unlikely to improve rapidly.

What this means for buyers in practice is that resale stock in well-maintained 2015–2020 vintage — originally built to the pre-RE2020 standard but with modern fittings and relatively recent structural condition — is looking like the best value play in many Alpine resorts. These properties trade below new-build per square metre, avoid the full weight of DPE concerns affecting older stock, and offer immediate possession. The pure new-build case remains strongest for tax-efficient investor buyers targeting the VAT reclaim and for buyers who specifically want the lowest possible running costs and the RE2020 thermal advantage.

For Domosno’s buying clients, the practical result is that we now recommend a more balanced split between new-build and well-chosen mid-vintage resale than was typical before the cost pressure era.
