When launching a wooden frame construction project with Natilia, the first question quickly arises: how much does it really cost, excluding land, for a turnkey house? The answer depends on parameters that online pricing grids do not always show. The price varies according to the surface area, the level of finishes, and the region, but especially according to technical constraints related to the soil and current regulations.
RE2020 and wooden frame: why Natilia absorbs regulatory increases better
Since the generalization of RE2020 for new individual houses, all builders must comply with a carbon indicator during the construction phase (IC construction). Traditional masonry builders have had to invest in costly technical solutions to meet the regulatory baseline: enhanced insulation, more sophisticated ventilation and heating systems.

For a builder like Natilia, which works with industrialized wooden frames, wood offers a structural advantage on the carbon indicator. The material stores CO₂ instead of emitting it during its production, allowing compliance with regulatory thresholds without piling on technical costs.
According to the report from the Strategic Committee for the Wood Sector published in 2024, the upward pressure on the prices of wooden houses remains lower than that on concrete houses with equivalent energy performance. To better understand the average price of a Natilia house in 2025, this structural advantage must therefore be taken into account.

In practice, it is observed that RE2020 did not cause the same price shock at Natilia as it did with traditional builders. This does not mean that prices have not changed, but the cost gap with masonry has narrowed to the benefit of wood.
Cost of wooden materials in 2025: stabilization after the surge
Between 2021 and 2022, the price of softwood sawn timber (spruce, Douglas fir) used in framing skyrocketed dramatically. This post-Covid surge raised quotes for all wooden builders, including Natilia.
Since then, prices have stabilized. The rates for softwood sawn timber remain above their pre-2020 levels, but the upward trend has significantly calmed. For a Natilia project launched in 2025, the price fluctuations that rendered quotes obsolete within weeks are no longer felt.
This more predictable materials context allows Natilia to offer more stable pricing grids. Feedback on this point varies by agency, but budget visibility has improved compared to the 2021-2022 period.
What really affects the price of a Natilia house
Beyond materials and regulations, several factors can double a Natilia quote. Three key factors weigh heavily.
Soil type and foundations
Clay or sloped land requires special foundations (reinforced footings, deeper crawl spaces). On certain soils classified as having a risk of clay shrinkage-swelling, the G2 geotechnical study can reveal significant additional costs. This factor is often underestimated when looking solely at the catalog price of a model.
Living area and configuration
A small single-story house does not cost proportionally less than a larger two-story model. The roof, foundations, and technical lot (electricity, plumbing) represent a fixed base. The cost per square meter decreases as the surface area increases, making smaller models relatively more expensive per m².
Level of finishes and equipment
Natilia offers several levels of service. Between a “ready to decorate” delivery and a fully equipped house (kitchen, flooring, outdoor arrangements), the budget gap can represent a significant portion of the total cost. Here are the finishing items that weigh the most:
- Floor and wall coverings, whose prices vary greatly depending on the chosen material (entry-level tiles or solid wood flooring)
- The equipped kitchen, which can range from a basic setup to a high-end installation with integrated appliances
- Exterior joinery (triple glazing, motorized shutters) that improves thermal performance but increases the budget
- Outdoor space arrangements (wooden terrace, fences, accessibility features) often overlooked in the initial quote
Comparing a Natilia quote with traditional construction
It is often said that wooden houses are more expensive than concrete block houses. The raw comparison of prices per m² sometimes supports this idea, but it omits two decisive parameters.
The first is the construction time. An industrialized wooden frame goes up faster than a masonry house, which reduces the duration of the bridging loan or temporary rent. On a typical project that takes several additional months, this indirect cost can represent several thousand euros.
The second parameter concerns energy performance. A Natilia house achieves high insulation levels thanks to the very structure of the wooden frame, without requiring as many layers of added insulation as a concrete building. The energy bill during use reflects this, and the return on investment is measured over the building’s lifespan.
To compare fairly, it is recommended to think in terms of total cost: construction price, interim costs, energy costs over ten or twenty years, and any financial aid related to wooden construction or environmental performance.
Financial aids available for a Natilia project in 2025
Several programs can reduce the cost of a new construction that complies with RE2020:
- The zero-interest loan (PTZ) for first-time buyers, subject to income and geographical area conditions
- Local aids offered by certain communities to encourage ecological construction or the use of wood
- Temporary property tax exemptions granted by some municipalities to new constructions with high energy performance
These programs are not specific to Natilia, but wooden frame houses often meet the environmental criteria required for these aids. Checking their availability with the town hall and the local Natilia agency remains the first reflex before finalizing a financing plan.
A Natilia project therefore amounts to much more than the catalog price displayed for a model. Soil, finishes, timelines, aids: each parameter shifts the balance. Setting a realistic budget requires cross-referencing the builder’s quote with a soil study, a complete financing plan, and an estimate of usage costs over time.
