Discover what our clients think about our service

"A flexible multi skilled architect is the key to a successful build in France. I've been on site with Tim and the build team or at his house and the amount of day to day decisioning he filters (and does much better than you) is staggering."

"We worked with Tim on the refurbishment and extension of our home in the Aude. He provided professional advice on the planning of the work and dealt successfully with the Mairie. We were very pleased with the management of the contract, and the results have been admired by family and friends."

Frequently asked questions

Do I need an architect in France for renovation or construction projects

In France, an architect is legally required for certain renovation and construction projects, especially when structural changes are involved or when the total floor area exceeds regulatory thresholds. Even when not mandatory, working with an architect helps ensure planning compliance, technical accuracy, and long-term project success.

What types of projects does TH Architecture work on?

TH Architecture works on house renovation and restoration, barn conversion, château renovation, new build houses, commercial projects, and swimming pool design across France. Each project is approached with a strong understanding of planning regulations and architectural context.

Do you work with both local and international clients?

Yes. We work with clients based in France as well as property owners from the UK, USA, Europe, and other countries who own or are buying property in France. Projects are managed locally with clear communication throughout.

Can you advise before purchasing a property in France?

Yes. We offer pre-purchase architectural assessments to evaluate structural condition, planning feasibility, renovation potential, and likely costs. This helps buyers make informed decisions before committing.

Which areas of France do you cover?

TH Architecture undertakes projects across France, including the Loire Valley, Nouvelle-Aquitaine, Occitanie, the South of France, and rural regions. Services are not limited to a single department or city.
