Architect for Building Transformation

Are you looking to transform an old house, add an annex, or carry out works to rehabilitate a building? A specialist transformation architect is the professional you need. Renovating a building can be a delicate process, but thanks to their expertise, this architect takes charge of renovation projects from design all the way through to construction.

While many agree that an architect is an artist at heart, they are no less a technical and construction professional. Do not hesitate to call on this type of architect to transform your home and its interior to the fullest.

In practice, when should you hire a specialist transformation architect?

Architects are multidisciplinary professionals who master all the intricacies of renovation and construction projects — design, work supervision, budget management, administrative procedures, and more. Their involvement guarantees the success of your transformation project.

For the rehabilitation of a building
A building can have many lives, and its renovation creates spaces full of potential. In this type of project, the building's structure remains the same, but its interior is completely transformed. Room layout, utilities, décor, atmosphere — the architect can modify everything, going as far as removing certain non-load-bearing walls.
In structural renovation projects, the transformation architect may also work on the building's structure during more extensive works. This can include raising the roof, carrying out energy renovations, or even reinforcing the framework of a construction.

For the construction of an annex
Having an architect on board is mandatory when building an extension. But beyond the legal requirement, an architect's expertise is invaluable. Whether you are looking for a conservatory or a more substantial structure such as a detached studio, a garage, or a workshop, this professional will carry the project through to completion while respecting technical constraints, the budget, planning regulations, and the specific features of your environment — land type, soil conditions, and so on.

For simplifying administrative procedures
Finally, a specialist transformation architect supports you through all the administrative procedures involved. Planning permission applications, paperwork — the architect handles everything. With a thorough understanding of every aspect of their profession, they ensure compliance with the architectural regulations governing each region of France, whether in Paris or elsewhere.

Coquille is an architectural practice founded in Finistère in 2026 by Elisabeth Biville.

Its practice takes its name from Paul Valéry’s text L’Homme et la coquille, which explores the relationship between a form and what gives rise to it.

Coquille pays particular attention to the uniqueness of each project and to its coherence with a context, culture and patterns of use shaped over time. Whether transforming, extending or building, the practice seeks to anchor each project within its environment, with careful consideration for the places, materials and people who bring them to life.
