Transforming a barn into a cozy mountain chalet in La Plagne, Les Arcs

When converting a barn in La Plagne or Les Arcs , the true essence of the project lies in preserving its unique character and history. My approach is strongly based on heritage reuse , a method that is both aesthetically pleasing and environmentally friendly.

Rather than wiping the slate clean, the goal is to repurpose the original materials and give them a spectacular second life in your new chalet:

Valorizing old wood: The wood from old hay racks or floors worn by time is recovered to design a monumental custom-made farmhouse table, becoming the centerpiece of your dining room.

Repurposing antique objects: An old stone or solid wood manger, once carefully restored by professionals, becomes a unique and sculptural bathroom sink.

For a mountain chalet to be truly comfortable in winter, it must offer impeccable modern amenities without technology disrupting its traditional charm. Contemporary luxury lies in discretion.

The art of intelligent contrast in interior design consists of combining the history of the place (exposed stone, old wood, natural plaster) with completely concealed, state-of-the-art home automation equipment:

Stealth technology: I integrate acoustic speakers directly into the walls (invisible under the plaster) and recessed stage lighting. The atmosphere is enhanced, with no visible cables or equipment, thus preserving the illusion of a timeless mountain retreat.

Connected heating and home automation: Remote thermal comfort management allows you to arrive in a perfectly heated chalet, while preserving the rustic aesthetic of an old wood stove or a stone fireplace.

The main advantage of a barn conversion lies in its grand volumes and soaring ceiling height. While creating a large, bright living space is essential, these immense mountain spaces can sometimes lack warmth.

To structure this vast space and create a truly “cocooning” atmosphere, my work as an architect plays with the concept of “box within a box” and secret hiding places:

Integrated shelters: The creation of a fire pit below (the conversation pit ) or the creation of cozy cabin beds embedded in the thickness of the old stone walls brings that feeling of security and comfort specific to winter evenings at altitude.

Suspended spaces: The installation of a suspended net stretched under the roof structure offers a reading nook suspended above the void, optimizing space while adding a playful touch.

A successful chalet renovation project must be deeply connected to its surroundings. The complexity of these unique projects requires a carefully selected network of contacts.

By choosing my architectural firm, you also benefit from an exclusive collaboration with local artisans and designers. Whether it’s a blacksmith from the valley for a custom-made metal staircase, a wood sculptor to enhance a timber frame, or a regional weaver for your decorative textiles, this expertise guarantees top-of-the-range quality and a true Alpine character for your interior.

Do you need a building permit to convert a barn into a dwelling? It depends. If changing the use of an agricultural building to residential is necessary, a building permit is always required. Professional guidance is often essential to prepare a strong application that complies with the strict planning regulations in mountain areas. If the property is already used as a dwelling, a prior declaration of works may be sufficient for facade modifications. Each case must be assessed individually.

How much does it cost to convert a barn into a chalet? The budget for a complete barn renovation is often comparable to, or even higher than, that of a new build, due to structural constraints (underpinning, utilities, insulation). Expect to pay on average between €2,500 and €4,000 per square meter, depending on the condition of the building and the desired level of finish.

Why choose an interior designer for this mountain project? An interior designer does more than just decorate. They optimize complex spaces, manage technical constraints (insulation, running utilities through old walls), and coordinate local contractors. They ensure the project’s coherence, from the selection of an antique beam to the integration of invisible home automation, to create a truly bespoke living space.


A property in the mountains can become an exceptional place… or a complex, poorly planned project.

Before buying a chalet or apartment in Savoie or Haute-Savoie, it is essential to assess:

– its true potential,

– technical constraints,

– renovation costs,

– and the possibilities for optimization.
