ATHERAC, exclusive member of Christie's: a recognition of our alpine expertise

Giving mountain real estate its full place… right in the heart of the village

If you've taken a stroll along the Route des Grandes Alpes in La Clusaz recently, you'll no doubt have noticed a new ATHERAC storefront, flanked by Christie's banners. This new branch, located at 181 route des Grandes Alpes, is entirely dedicated to transactions. It's a way for our team to give this historic pillar of our business the place and visibility it deserves.

Since 1958, ATHERAC has been assisting families and investors with their real estate projects in the Aravis region. Our strength lies in our local presence and our involvement in the life of the resort. But now we're taking things a step further by joining a world-renowned network: Christie's International Real Estate.

An exclusive affiliation in the Aravis

What does it mean to be affiliated with Christie’s? It is a recognition of our seriousness, professionalism, and above all, our ability to support a demanding clientele in their mountain property purchase or sale projects.

ATHERAC is today the sole exclusive member of Christie’s International Real Estate in the Aravis, a sought-after area encompassing La Clusaz, Le Grand-Bornand, Manigod, Saint-Jean-de-Sixt, Thônes, and surrounding villages. This affiliation strengthens our positioning in the high-end market while staying true to our values of accessibility, proximity, and authenticity.

No "luxury," but meaning and quality

At ATHERAC, we don’t talk about "luxury real estate," a term often overused. What matters to us is functional value, mountain character, location, potential… and the quality of service we provide, whatever the size or budget.

Our range extends from renovated ski studios to architect-designed chalets with panoramic views, with tailor-made support at every step: valuation, marketing, showcasing, rental study, and signing. We also meet the expectations of an international clientele, notably English, Belgian, Dutch, and Swiss buyers seeking mountain properties.

A showcase for La Clusaz, a showcase for the Aravis

Our partnership with Christie’s also means access to an international distribution platform, a network of qualified buyers, and enhanced visibility for the properties we select.

But above all, it is an exceptional showcase for our territory: La Clusaz, its hamlets, its typical mountain chalets, family residences, open views… A unique market that deserves an expert eye.

A dedicated sales team, in an agency designed for you

With this new address at 181 route des Grandes Alpes, ATHERAC Transaction is affirming its identity. The agency has been entirely designed to welcome buyers and sellers in a warm and welcoming space, rooted in the local architecture. You'll find a team dedicated to your project, whatever your objectives: second home, resale, rental investment or heritage acquisition.
