Located between the Jura Mountains and Greater Geneva, the Pays de Gex is home to a wide variety of properties: single-family homes, newer villas, and apartments near the Swiss border. Renovating them in depth calls for a professional who can keep the design, the technical considerations, the budget, and the construction work all moving in step.
Atelier Christophe Sarlandie has an office at 288 Avenue de Genève in Divonne-les-Bains, in the heart of the Pays de Gex. Founded in Lyon and later expanded to Divonne-les-Bains, the studio designs and manages complete house and apartment renovations in Divonne-les-Bains, Ferney-Voltaire, and Gex, providing full project management from the first sketch to final handover.
Being based locally makes all the difference day to day: design meetings at the office, regular site visits, and a quick response whenever something unexpected comes up. You work with a professional who is right here in the area, not a firm managing your project from afar.

Before drawing anything, the studio analyzes the orientation, light, proportions, and flow of the space, as well as the way you live in it. Layout options then take shape in floor plans, perspective drawings, and 3D visualizations until every detail of the project has been approved. Special attention is given to making the most of what already exists: transforming and adapting rather than replacing everything, for more sustainable results.
The studio invites contractors to bid using detailed bid documents, compares their quotes side by side, verifies insurance coverage, and draws up the schedule. It then manages the trades from its Divonne-les-Bains office through to final handover, keeping close track of budget and deadlines throughout the project.
From bookcases and walk-in closets to kitchens, custom furniture becomes a natural extension of the architecture. Decor and furnishings are part of the same cohesive vision, chosen with everyday comfort in mind.
In a border region, the question comes up quickly: which professional should you trust with your project, and what assurances do you have? Christophe Sarlandie holds a rare distinction: professional recognition in both countries. In France, he is an accredited member of the French Council of Interior Architects (CFAI), where he has served as vice president since 2024. In Switzerland, his expertise is recognized by VSI-ASAI, the country’s leading professional association for interior architects. He also sits on the ECIA (European Council of Interior Architects), where he represents French interior architects.
In practical terms, this means qualified professional practice on both sides of the border, adherence to the profession’s code of ethics, and nearly 20 years of experience in demanding renovations. He holds the Diplôme Supérieur en Architecture Intérieure (Advanced Diploma in Interior Architecture), personally oversees every project, and deliberately limits the number he takes on each year.
The studio works with business leaders, entrepreneurs, independent professionals, and the many international clients who live in the Pays de Gex and Greater Geneva.
An initial conversation, held at the Divonne-les-Bains office or on site, to understand your needs, gauge the property’s potential, and establish what is feasible.
Floor plans, diagrams, and 3D visualizations bring the layout options to life, and each option is refined in working sessions. Depending on the technical demands of the project, the studio draws on the expertise of a surveyor, an acoustic engineer, an energy consultant, a lighting designer, or an engineering firm.
Once the permits have been secured and the contractors selected, construction begins under the studio’s supervision. This includes coordinating the artisans, tracking progress, and checking workmanship through to final handover, followed by the installation of the interior decor.
The Atelier operates primarily in Lyon and the Greater Lyon area, as well as in the Pays de Gex, the Geneva area, and the Annecy region.

The Atelier also considers complete renovation projects in other areas of the Auvergne-Rhône-Alpes region and the Lake Geneva area—in both France and Switzerland—depending on the nature, scale, and timeline of the project.

To get a sense of where your project stands, Atelier Christophe Sarlandie offers an online cost estimator that provides an initial budget range based on your property’s characteristics.

The French Council of Interior Architects (CFAI) accredits professionals whose training and experience meet the standards of the profession: strong design skills, technical expertise in renovation, and adherence to professional rules and a code of ethics. Working with a CFAI-accredited interior architect such as Christophe Sarlandie in the Pays de Gex helps safeguard a complete renovation, especially when the assignment includes full project management and construction oversight.
A villa in Divonne-les-Bains, a family home in Gex, an apartment in Ferney-Voltaire: every property deserves a design created specifically for it. The studio welcomes you to its Divonne-les-Bains office to discuss your project, then guides you from the first sketch to final handover.
