House Building Budget in France: How to Plan Costs

10 min read

Budget Is Everything

Building your own house is exciting, but it’s crucial to have a realistic view of costs before you start. Too many projects go over budget because not all cost items were anticipated.

The Main Budget Items

1. The Land

Land prices vary enormously by location. Factor in:

  • Legal fees (~8% for land in France)
  • Servicing if needed
  • Boundary survey by a surveyor

2. Construction

Construction cost depends on many factors:

Type Price range per m²
Entry-level house €1,200 – €1,500/m²
Mid-range house €1,500 – €2,000/m²
High-end house €2,000 – €3,000/m²
Self-build €800 – €1,200/m²
COST PER M² BY CONSTRUCTION TYPE SELF- BUILD 800 - 1 200 € ENTRY LEVEL 1 200 - 1 500 € MID- RANGE 1 500 - 2 000 € HIGH- END 2 000 - 3 000 € Indicative prices per m² of living space — excl. land

3. Often-Forgotten Extras

⚠️ Warning — These items easily represent 15–20% of the total budget and are often underestimated:

  • Development tax
  • Utility connections
  • Soil study
  • Builder’s warranty insurance
  • Outdoor works (fencing, driveway, garden)
  • Fitted kitchen
  • Moving costs

4. Contingency

💡 Tip — Always set aside a 10–15% contingency on the total budget. This is non-negotiable. Building projects always have surprises.

A well-prepared budget is the guarantee of a stress-free project. List every item, cost them accurately, and always keep a margin.
