L'AGENCE SPATIALE is available for new projects

Founded by architect Sophie LACHEN, after 15 years of professional experience in architecture and urban planning in Lyon, Marseille, Bastia, and Grenoble, L’Agence Spatiale designs unique living spaces, tailored to the tastes of those who inhabit them.

An eco-design approach

Its specificity lies in an eco-design process: each intervention is rooted in its architectural and landscape context, while every design choice seeks to minimize environmental impact.

Each project is conceived as a unique response, finely adapted to the rhythms of its occupants’ lives. The agency creates functional and harmonious spaces where every detail matters.

Natural light plays a central role in its approach—it structures volumes, amplifies perceptions, and creates atmospheres. The design method also includes in-depth work with color, capable of shaping moods and enriching spaces.

The agency develops renovation, construction, extension, elevation, and interior architecture projects, as well as the rehabilitation of historic housing, and also operates in mountain areas.

For professionals, it provides space planning services that reflect their brand identity.

With expertise in analyzing urban planning regulations and natural risks, the agency offers rigorous support to clients for their various planning permission requests.

Eco-certified materials, natural lighting, indoor comfort.

L’Agence Spatiale favors clean lines, balanced proportions, and carefully selected materials to combine aesthetics, durability, and sustainability—while promoting local supply chains whenever possible. Special attention is given to indoor air quality: material and finish choices take into account their composition and safety, ensuring a healthy and pleasant living environment.

Volumes, circulation, natural light, thermal and acoustic comfort, material choices, color palette, and finishes are all coordinated with precision to guarantee formal coherence and lasting comfort.

Tailor-made support

The agency works on both full and partial missions. It also offers advisory services prior to real estate purchases or renovation works, as well as dedicated support for color design and decoration.

Client support is one of the agency’s core values. Each stage of the project is built through dialogue, thanks to a structured working method and visual communication tools (detailed illustrated plans, 3D views, material and color samples) that provide clients with a clear and shared vision. This process ensures precise architectural guidelines aligned with expectations and technical constraints.

Craftsmanship and quality execution

The agency highlights artisanal know-how, collaborating with local craftsmen (carpenters, cabinetmakers, metalworkers, etc.) to design bespoke elements. This connection with craftsmanship allows for unique creations and personalized projects.

It operates mainly in the Auvergne-Rhône-Alpes region—notably Grenoble, Lyon, Savoie, Haute-Savoie, and the Geneva area—as well as in southeastern France, down to the Mediterranean coast.
