Financing an Autoconstruction: What You Need to Know

Building your own home—known as autoconstruction—can be an exciting and rewarding project, but financing it presents unique challenges. Here’s what you need to know to prepare for a successful build:

1. What is Autoconstruction?

Autoconstruction involves managing and often physically contributing to building your own home. This approach can lower costs but requires meticulous planning, budgeting, and organization.

2. Bank Loans for Autoconstruction

Traditional mortgages are typically designed for buying finished properties. For autoconstruction projects, you’ll likely need a special type of loan called a construction mortgage (prêt à l’autoconstruction or prêt à la construction). Banks may require project plans, permits, a detailed budget, and sometimes proof of experience before approving the loan.

3. Disbursement Schedule

Construction loans are usually given out in stages (tranches) as your build progresses and specific milestones are achieved (foundation, structure, roofing, etc.). Expect regular site inspections by the lender.

4. Self-Financing & Savings

Most banks won’t cover 100% of your costs. Be prepared with a personal contribution—often 15–30% of the project cost. Additional personal savings can help cover unforeseen expenses.

5. Government Grants & Support

Check for regional or national programs that might offer grants, subsidies, or tax credits for new builds, especially if you adopt eco-friendly or energy-efficient measures.

6. Professional Guidance

Even if you’re managing the build, consulting professionals like architects, appraisers, or financial advisors can help avoid costly mistakes and ensure your project is realistic.

Conclusion

Financing an autoconstruction is possible, but requires thorough preparation, a robust financial plan, and clear communication with lenders. Starting with the right information will help turn your dream home into reality.
