F.A.Q
Frequently asked questions
Are you planning to build, renovate or transform your interior, but you don't know where to start?
You are not alone. Many people hesitate to contact an architect or interior designer because they are unsure what to ask, what is required, or how much it might cost.
That’s why we’ve gathered here the most frequently asked questions we receive to help you feel informed, reassured, and ready to get started.
Whether your project is in Plouhinec, Lorient, Vannes, or elsewhere in Morbihan or the Brittany region, these answers are here to guide your first steps.
Our agency is based in Plouhinec - Morbihan (56), but we regularly work on projects in Lorient, Vannes, Quimper, and throughout Bretagne. Whether you're in an urban or rural area, we adapt our services to your local context.
Yes, in many municipalities in Morbihan and Finistère, even exterior renovations require a prior declaration.. For extensions or changes of use, a building permit is required. We assist you with all the procedures, working with local town halls such as those in Plouhinec, Lorient, and Vannes.
In France, as soon as the floor area exceeds 150 m², an architect is required. Even below this level, working with an architect in Plouhinec or elsewhere in Brittany guarantees you a coherent, compliant, and creative approach..
Yes. We offer specific support to regularize work carried out without authorization in municipalities such as Quimperlé, Auray and Guidel. This includes an administrative assessment and the preparation of a regularization permit with the relevant town hall.
This depends on the type of project and its location. In protected areas and ABF perimeters (e.g., the historic center of Quimper), lead times may be longer. On average:
Interior design : 1 to 3 months
Complete renovation with permit application : 6 to 12 months
We provide you with a schedule from the very beginning.
The cost of a renovation depends on many factors: surface area,building's initial condition, desired level of finish, materials used, technical complexity, and the project's location (seaside, heritage area, etc.).
At Atelier Glaz, we never offer generic prices. Each project is subject to a personalized assessment, followed by a detailed quote tailored to your needs and budget.
