Our luxury real estate in Chamonix

Located in the heart of the valley, our Chamonix Sotheby’s International Realty agency welcomes you in the centre of Chamonix. Taken over by Lionel and Sonia Thomas in 2019, the agency is a reference in luxury real estate in the valley.

Catering, accommodation, communication, 5* hotels…With their expertise in the luxury sector in France and abroad, in 2015, Lionel and Sonia created the first luxury real estate investment office in Chamonix: "Mr and Mrs Thomas Private Office", which quickly built up a good local reputation.

This successful experience encouraged them to join the Sotheby’s International Realty network, the world leader in luxury real estate.

Supported by their faithful collaborators, Anna Gatta and Jessica Herry, sales consultants, Lionel and Sonia have surrounded themselves with a team of men and women who are passionate about their profession. The team now counts 8 members.

United by mountain sports (hiking, skiing, climbing, trail running) and their attachment to the valley, our experts put their perfect knowledge of the local prestigious real estate market at your service. With them, you benefit from discreet and personalised support to carry out your project for the sale or acquisition of exclusive properties.

Each of the properties that we offer for sale is the subject of a rigorous selection, whatever the nature of the property:

• Chalets and half-chalets
• Country houses
• Apartments
• Farmhouses
• Land to build

Whether in Chamonix, Servoz, Vallorcine, Les Houches, or Argentière (where our second branch is located), we are at your disposal to help you find the home that suits your lifestyle. Discover our exclusive properties located:

• At the foot of the slopes,
• In the town centre,
• In the middle of nature,
• In a location with stunning mountain views.

Would you like to sell your property in the valley? We support you and advise you at every stage of the transfer of your property in complete confidentiality.
