Construction Stages

The price depends on several factors: floor area, layout, options, assembly, and transport, among others.

As a general guide:

- The planning application triggers a fixed payment of €1,400 to €1,800, depending on the size, which is fully refunded in the event of a definitive refusal. This payment initiates kit production.

- The kit starts from XXX €/m²

- The assembly option starts from €800/m² (structure installed)

We always provide a personalised, transparent and detailed quotation before any order.

On average:

- Studies and planning permission: 1 to 3 months

- Manufacturing: 8 to 12 weeks

- Delivery: scheduled with you to suit your site timetable

Our timber comes from responsible supply chains. We select PEFC- and/or FSC-certified wood, ensuring every felled tree is replaced within sustainably managed forests. This traceability limits environmental impact and guarantees consistent timber quality (fir, spruce, larch, Douglas fir).

Manufacturing is French and European.
- Most components (structure, joinery, roofing) are produced in France or the European Union in specialised, certified factories.
- Insulation materials (wood fibre, glass wool, cellulose wadding) and structural panels comply with RT 2012 thermal requirements, currently transitioning to RE 2020.

Our kits benefit from several recognised certifications:

- France Bois Certifié label: awarded exclusively to PEFC- or FSC-certified forests, guaranteeing sustainable forest management.

- CE marking for construction products: all structural panels, insulation and fixings comply with European standards for safety, mechanical strength and energy performance.

- NF Habitat & HQE (High Environmental Quality)
  - Our homes are eligible for the NF Habitat label, which ensures performance, airtightness, and indoor air quality.
  - For bespoke projects, the HQE approach can be applied to ensure a holistic focus on energy efficiency, health, acoustic comfort, and water management.

- CQFD label (Cost – Quality – Reliability – Deadlines): some of our partners (e.g. BH SAS) hold this label, awarded by the French housing authority, certifying controlled costs, technical reliability and respect for deadlines.

Yes, unless otherwise agreed in writing, payment terms are as follows:

- At order (quotation signature): 30% deposit of the total amount excl. VAT (kit + additional services)

- At the start of kit production: 40% excl. VAT

- Before dispatch: remaining 30% excl. VAT

With the Turnkey Package, an additional initial deposit of 10% may be required once final plans and planning permission are approved.

Yes:

- Legal conformity guarantee

- Hidden defects guarantee

- Manufacturer warranties (5 to 25 years, depending on the product): all manufacturers are covered by Civil Liability and Decennial insurance, protecting you in case of defects (leaks, infiltration, structural issues).

- 10-year structural warranty on the timber frame: the entire timber structure is covered for a period of 10 years, guaranteeing the structural integrity of your home.

- Joinery warranties:
  - 10 years on airtightness and operation of windows and doors (glazing, timber/aluminium frames)
  - 5 years on PVC profiles and hardware

Absolutely.

Our kits are designed for skilled tradespeople or careful self-builders. However, we draw your attention to the essential legal, administrative, and technical requirements to ensure compliance, safety, and long-term durability. We provide all the necessary information to help you complete your project successfully.

For self-build projects, the following steps are mandatory:

- Planning permission or prior declaration

- G1/G2 soil survey

- Structural study and foundation plans by an engineering office

- Construction insurance (Dommages-Ouvrage)

We provide a clear checklist to help you move forward with confidence.

Site preparation is a crucial step in ensuring the durability, stability and compliance of your future home.

Important:

The steps outlined below are general guidance only and do not replace the recommendations of a qualified engineering professional (geotechnical engineer, structural engineer, project manager, etc.), unless explicitly included in your contract.

1.Soil survey (G1, G2):

- Carried out by an approved geotechnical engineering office.

- Determines soil type (clay, silt, backfill) and appropriate foundation system (strip footings, raft slab, piles)

2.Foundation base:

- Ensure the ground is stable and well-drained.

- Install a crushed stone layer (200 mm) plus a sand layer (200 mm) for load-bearing capacity and drainage.

3.Reinforced concrete slab (200 mm):

- Built according to structural plans. Insulated with extruded polystyrene XPS (50 mm) if required (cold climate zones).

- Allow for service ducts (water, electricity, drainage) before pouring.

- A structural engineering office must validate all prerequisites after the soil survey. Our partners can provide foundation quotations if you choose the Turnkey package.

4.Curing & drainage:

- Allow a minimum of 28 days for curing before starting frame assembly.

- Install perimeter drainage if required (wet areas, high water table).

Note: For difficult access or complex site conditions, our engineering office can propose alternative solutions (driven piles, full raft slab).

Our support does not stop at the delivery or completion of works:

- Ongoing technical assistance
  - Telephone support available Monday to Friday (9 am – 6 pm) for questions relating to assembly, insulation or finishes.
  - Site visits available (quoted separately) to check progress and validate critical points (airtightness, joinery).

- Post-delivery quality checks
  - A complete inspection is carried out with our partners six months after delivery (checking for leaks, insulation, floors, joinery). 
  - Issuance of a compliance certificate confirming that any reservations have been resolved.

- Optional extended warranties
  - Additional 5-year warranty options available through our partner insurers (joinery, roofing, frames) or construction insurance.
  - We provide quotations and guide you towards the most suitable, competitively priced options.
