How much should you budget per square metre to build a house today? What overall budget (land + construction) should you plan for to avoid surprises during the build?
The construction cost per m² is a key benchmark. In this guide, we provide average price ranges for 2024 to 2026, along with the calculation method and a breakdown of cost components per m². For specific questions about your land purchase or construction project, contact your local Capifrance property advisor and consult the FAQ at the end of the article.
In summary:The construction cost of a house generally falls between €1,500 and €2,500/m² excluding land, with an average typically observed around €1,700 to €1,900/m² for a standard project carried out by a builder.To calculate your budget accurately, you need to distinguish the construction cost excluding land from the overall project cost, which also includes the land, servicing, connections, taxes, insurance and notary fees.The price per m² varies significantly depending on the type of construction (CCMI, architect, self-build, kit home), the region, the nature of the land, the level of finish and the expected energy performance.To avoid unpleasant surprises, it is advisable to request detailed quotes, compare services on the basis of habitable floor area (SHAB) and allow a safety margin of 10 to 15% for contingencies.
What does the construction cost per m² cover and how do you calculate it?
The "construction cost per m²" is a useful financial benchmark. It can cover different realities depending on the context. A distinction must be made between the price per m² excluding land and the price per m² including it (land + construction). The recommended basis for comparison remains the habitable floor area (SHAB). Practical formula: total construction cost excluding land ÷ SHAB = construction cost per m². This result varies depending on materials, labour, VAT, the builder's margin and the options chosen.A price per m² quoted by a builder often covers the structural work, secondary works and standard finishes. It frequently excludes the land, servicing, connections, the development tax and notary fees. Always check the detailed list of services in the quote to compare accurately.Variables to take into account: choice of materials, labour costs, surveys (G1/G2), servicing, taxes and the builder's margin. Before signing, ask about the contractual terms (CCMI or works contract) and allow a safety margin of 10 to 15% for contingencies.Key takeaway: distinguish the price per m² excluding land from the overall cost (land + construction). Glossary: SHAB = habitable floor area; CCMI = individual house construction contract; RE2020 = applicable environmental regulation.
Precise definition: floor area and interpretation of the cost per m²
The habitable floor area (SHAB) is the most reliable basis for calculating a price per m². The SHON, usable area or other metrics can skew comparisons if they are not specified. Annexes such as the garage or terrace are sometimes excluded from the SHAB. Check whether they are included.Always ask the professional for the price expressed in €/m² "SHAB" and the list of services included. This makes it easier to compare a price per m² inclusive of VAT with one exclusive of VAT, or a turnkey package with a works contract.
Practical formula and variables to consider
Simple formula: construction cost excluding land ÷ habitable floor area (m²) = cost per m². Mini example: €150,000 ÷ 90 m² = €1,666/m² (price per m² excluding land).Variables to factor in: material costs (timber, steel, cement), labour, soil survey, earthworks, foundations, servicing, development tax and builder's margin. Do not forget VAT for new builds (generally 20%) and structural damage insurance (assurance dommage-ouvrage) in the ancillary costs.
Benchmark figures and current construction cost trends
For 2024–2026, national benchmarks give an indicative range of €1,500 to €2,500/m² excluding land. The average observed in 2025–2026 is often around €1,700–€1,900/m² for a project carried out by a standard builder. Self-build can come down to around €1,200–€1,600/m². High-end projects frequently exceed €3,000/m².Material inflation and the application of RE2020/RE2025 have pushed costs up. According to ministerial sources and industry observatories, the cumulative increase between 2022 and 2023 reached approximately +10 to +20% depending on the category. These figures vary according to region, building type and the type of professional involved.Comparing new and old: new build costs money to construct, but it delivers better energy performance and guarantees. Buying an existing property and renovating it can be more expensive if the works are extensive. Request a local estimate to get an accurate picture.To consult the energy regulations, see the RE2020 page on the ministry website: https://www.ecologie.gouv.fr/re2020.
National price ranges and cost per m² by construction type
Indicative price ranges excluding land (VAT-inclusive figures for guidance, 2024–2026 data):
Construction method | Indicative range (€/m² excl. land) | Notes |
|---|---|---|
Self-build | €1,200 – €1,600/m² | Labour savings but increased responsibilities |
Builder / CCMI | €1,500 – €2,000/m² | Turnkey package with delivery guarantees |
Bespoke architect | €1,800 – €3,500+/m² | Strong variation depending on the level of finish |
Kit home / Timber frame | €1,300 – €2,200/m² | Fast assembly, variable performance |
These ranges depend on the level of finish. A house delivered in shell form does not include a fitted kitchen or certain finishes. An "all-inclusive" price incorporates more cost items.
Regional variations: price per m² by region
Location is a decisive factor. Île-de-France, coastal areas and major cities show higher prices. In rural areas, the construction cost per m² can fall below €1,500/m². In high-demand zones, it frequently exceeds €2,000/m².The price of land often accounts for 30 to 50% of the total budget in high-demand areas. Consult a regional price per m² map to refine your benchmarks and request a local estimate from an advisor.
Factors that cause the cost per m² to vary
Several factors explain the dispersion of prices: type of professional, level of finish, architectural complexity, nature of the land, environmental standards and market conditions. Anticipating these elements helps to keep the budget under control and prioritise the key cost items.Examples of impact: high-end finishes +20 to +40%. Sloping land or clay soil: additional foundation costs +10 to +25%. Investing in energy performance increases the initial cost but reduces the running cost over the long term.An extended construction period or poorly negotiated penalties will increase the budget. List the factors influencing the price per m² from the design phase onwards.
Type of professional: builder, architect, contractor, self-builder
The CCMI offers solid guarantees: ten-year warranty, completion guarantee and delivery at the agreed price and within the agreed timeframe. The CCMI ensures a controlled price and schedule. It is, however, often slightly more expensive than other options.An architect offers bespoke design. Their fees are generally higher, particularly for high-end projects. A works contract or project manager allows for greater personalisation but offers fewer guarantees than a CCMI.Self-build allows for significant savings, sometimes 20 to 40%. It does, however, require a strong personal commitment and carries risks. Kit homes simplify the build process, but outsourced options and finishes quickly increase the bill.
Level of finish, equipment and materials
The level of finish has a major influence. The fitted kitchen, joinery, floor coverings and home automation all cause the price per m² to vary. High-end finishes increase costs significantly.Choice of materials: a timber frame delivers thermal gains. A masonry house can be cheaper to build. High-performance heating systems (heat pump, dual-flow ventilation) cost more to purchase but improve energy performance and resale value.
Breakdown of cost items: what does each m² represent?
Indicative breakdown of costs excluding land: structural works 30–40%, secondary works 30–40%, finishes 15–25%, external works/utilities 5–10%, surveys and insurance 3–7%. These benchmarks are useful for identifying abnormally low quotes or missing cost items.Analysing the cost per item per m² makes it easier to make trade-offs. Reducing finishes in favour of better insulation is often a worthwhile decision. A cost breakdown infographic helps to visualise these proportions when comparing quotes.
Structural works: earthworks, foundations, structure, roof
Structural works cover earthworks, foundations, walls, roof structure and roofing. A soil survey (G1/G2) is often essential. Allow between €800 and €3,000 depending on the complexity of the site.Sloping land or clay soil generates additional costs for the foundations. Local planning constraints (PLU, ABF) may impose costly solutions. Request the soil survey before purchasing to avoid surprises on site.
Secondary works and finishes: insulation, plumbing, electrics, coverings
Secondary works cover insulation, plumbing, electrics, heating, partition walls and floor and wall coverings. The most sensitive items are the fitted kitchen and bathroom, which can account for a significant share of the finishing costs.Depending on the level of finish, secondary works and finishes account for 15–25% of the budget excluding land. Choosing high-performance equipment reduces running costs despite a higher initial outlay.
Ancillary costs to factor in: land, servicing, taxes, insurance
Ancillary costs are often underestimated: land price, notary fees, development tax, servicing, connections and insurance. The price of land can represent 30–50% of the total project depending on the area.Indicative costs: notary fees on the land ≈ 6–8%. Servicing: €5,000 to €30,000 depending on the situation. Structural damage insurance (assurance dommage-ouvrage) to be budgeted for. Before purchasing, request a full estimate of ancillary costs to budget your project accurately.
Construction methods: what cost per m² depending on the solution chosen?
Each construction method combines cost, guarantees and personalisation differently. A comparative table of cost vs. guarantees vs. personalisation helps in choosing the right solution.The CCMI secures the project. An architect offers bespoke design. Self-build reduces the bill but increases the workload and risks. Kit homes and timber-frame buildings can shorten lead times. The price per m² always depends on the level of finish and the options chosen.
Turnkey construction: guarantees and cost
The CCMI includes statutory guarantees: ten-year warranty, completion guarantee and delivery at the agreed price and within the agreed timeframe. This security often explains a premium on the builder's price per m² but limits financial and legal risks.Check the contract clauses: delay penalties, deposits, payment calls and payment schedule. Require a detailed quote for each item in order to compare offers objectively.
Self-build and kit homes: savings and limitations
Self-build allows you to save money by contributing your own labour. Savings can reach 20–40%. However, it requires managing the project, ensuring compliance with regulations and taking out compulsory insurance.Kit homes offer a standardised and fast solution. Outsourced options and finishes quickly increase the bill. Prepare a detailed construction budget checklist and a strict schedule to keep costs under control in a self-build project.
Practical cases and tools to estimate your budget
Two mini case studies illustrate the calculation and cost sensitivity. Use a simulator or request personalised estimates to refine these scenarios according to your region.Checklist to compile for a simulation: habitable floor area, desired level of finish, nature of the land, local planning rules (PLU), servicing, type of builder and regional benchmarks. Add a contingency margin of 10 to 15% to secure the budget.
Mini case 1 — 100 m² standard house
Assumptions: "average price" region, CCMI builder, price per m² excluding land = €1,700/m², floor area = 100 m². Construction cost excluding land = 1,700 × 100 = €170,000.Ancillary costs (assumption): land price = €80,000, servicing = €8,000, notary fees (6%) = €4,800, development tax = €3,500, structural damage insurance = €1,800. Total ancillary costs = €98,100.Contingency margin (10%) on construction = €17,000. Total project cost = €170,000 + €98,100 + €17,000 = €285,100. That is approximately €2,851/m² relative to the overall project.
Mini case 2 — 120 m² high-end house
Assumptions: architect, high-end finishes, price per m² excluding land = €3,200/m², floor area = 120 m². Construction cost excluding land = 3,200 × 120 = €384,000.Sloping land with clay soil: land price = €120,000, soil survey = €2,500, reinforced foundations (+15% on structural works) ≈ €18,000, complex servicing = €15,000, notary fees (6%) = €7,200. Ancillary costs = €162,700.Contingency margin (15%) = €57,600. Total project cost = €384,000 + €162,700 + €57,600 = €604,300. A 10% rise in material costs would add approximately €38,400 to the total.

Then add ancillary costs (land, servicing, notary fees, insurance) to obtain the overall cost.What is included in a builder's price per m²?A "turnkey" builder's price usually includes structural works, secondary works and standard finishes. It often excludes the land, servicing, connections and certain options. Check the detailed list in the contract.How can you reduce the price per m² without compromising on quality?Negotiate quotes, standardise the floor plan, prioritise structural items, choose high-performance materials and compare multiple offers. Consult a local advisor to make informed trade-offs.What financial assistance can reduce the construction cost per m²?Schemes such as the PTZ (subject to 2026 conditions), local grants or tax exemptions can ease financing. Check eligibility and conditions with an advisor and the relevant public services.Self-build: what price per m² should you budget for?Self-build can reach approximately €1,200–€1,600/m² excluding land depending on your level of involvement. Be aware of responsibilities, regulatory compliance and the compulsory structural damage insurance.What contingency margin should you allow in the budget per m²?It is recommended to allow a safety margin of 10 to 15% of the construction budget excluding land to cover contingencies and price fluctuations.How much does it cost to build a 150 m² house?The cost of building a 150 m² house depends on the market segment, choice of materials, heating system, geographical location and the professional engaged. In practice, for a new build, you should often budget between €225,000 and €375,000 excluding land, based on approximately €1,500 to €2,500 per square metre. The total budget can, however, be higher once ancillary costs are added: land purchase, servicing, connections, structural damage insurance, development tax and any architect or project manager fees. To avoid unpleasant surprises, you should think in terms of both cost per m² and overall project cost.What is the price per m² for a new build?The price per square metre for a new individual house generally falls between €1,500 and €2,500/m² excluding land. The price then varies depending on the type of property: traditional house, contemporary house, timber house or bespoke home designed with an architect. Construction costs also increase depending on the chosen specifications: insulation quality, joinery, heating system, finishes, complexity of the floor plan or requirements related to environmental regulations. An individual house builder often offers a clearer framework, with a construction contract that secures the price and timeline.Is it possible to build a house on a budget of €300,000?Yes, it is entirely possible to build a house with a budget of €300,000, but everything depends on the scope: house alone or house plus land. Excluding land, this amount often makes it possible to build a comfortable standard to intermediate-grade individual house, or even a well-equipped contemporary home depending on the region. However, if this budget also needs to cover the land purchase, ancillary costs, development tax and certain external fittings, the floor area or level of finish of the future house may need to be adjusted. The most important thing is to allocate the expenditure correctly and verify feasibility with a construction professional, builder or project manager.What type of house can you build for €200,000?With €200,000, it is often possible to build an entry-level or intermediate-grade house, particularly in rural areas or in locations where land costs remain moderate. This budget generally corresponds to a compact traditional house, sometimes with a first floor, featuring standard specifications and a simple floor plan. The outcome depends mainly on the type of project: single-storey or two-storey house, level of equipment, heating system, quality of finishes, and whether or not an architect is involved for a bespoke design. A timber house or a highly standardised solution can sometimes offer an economic advantage, but indirect construction costs must always be factored in, particularly servicing, connections and electrics.How much does it cost to build a house?The cost of building a house varies considerably depending on the type of house, floor area, land, technical complexity and level of finish. On average, the construction cost falls between €1,500 and €2,500 per square metre excluding land, but it can be lower for self-builds or higher for a high-end home designed with an architect. To estimate the price of a house accurately, you need to distinguish the cost of building the house itself from the overall project cost. Ancillary costs, the development tax, soil survey, connections, insurance and constraints related to the nature of the land all have a direct impact on the final amount.What budget should you plan for to build a house?The budget required depends on the desired floor area, location and expected specifications. For a standard new build, many households work on a base cost of between €1,500 and €2,500/m², then add expenditure related to the land and administrative formalities. This provides a first realistic estimate of the total budget for building a house. The main project criteria should then be refined: choice of materials, type of foundations, environmental regulations, interior specifications, whether to work with an individual house builder or a project manager, and land-related costs. For a reliable construction project, it is best to allow a safety margin of 10 to 15% to absorb contingencies and cost increases during the build.
