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.

Line Calder has been practising as an architect since obtaining her DPLG architecture degree, awarded by the French government in 1997, following studies that included a period at the University of Chicago.

She specialises in projects involving existing buildings, including alterations, interior reconfigurations, extensions, changes of use, restoration, rehabilitation, subdivision and more.

Her practice is based 70 km west of Paris, in the small village of Boutigny (28410), in Eure-et-Loir, near Houdan (78550) in the Yvelines. Her area of practice extends northwards to the banks of the Seine around Mantes (78200), eastwards to the outskirts of the Rambouillet forest (78120), southwards towards Chartres (28000), with its cathedral on the horizon, and westwards as far as the valleys around Mortagne-au-Perche (61400).

It is worth noting that in 2017, after 20 years of professional practice in France, she returned to Australia, her home country, to broaden her experience. She eventually resumed her architectural practice in 2025, bringing with her a renewed sense of enthusiasm and fresh perspective.
