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.

Graduated with a Master’s degree in Architecture from the Politecnico di Milano and an engineering degree from the École Spéciale des Travaux Publics, du Bâtiment et de l’Industrie (ESTP), Charles-Emile PERCHAUD obtained his authorization to practice as an independent project manager in 2018 at the École Nationale Supérieure d’Architecture de Versailles. He has been registered with the Île-de-France Order of Architects since 2024, alongside the creation of his firm. After ten years of experience in architectural practices working on large-scale tertiary, institutional, and interior architecture projects, he founded Atelier Perchaud to offer an expanded response to today’s and tomorrow’s construction and renovation needs.
