How much does it cost to build a chalet in  Chamonix-Mont-Blanc?

The potential advantages of choosing to build a chalet rather than buy are numerous: tax advantages, building it to your own requirements, and better amortisation of maintenance costs over the long term.

Our analysis also looks at the list of costs to be taken into consideration when building a chalet.

In practice, however, there is little data available on the actual cost of building a chalet in the Alps.

In order to provide more concrete information, the team of experts at OVO Network looked into the subject. Commune by commune, we have listed the details of the construction costs of two chalets intended for seasonal rental.


The initial data for each case study are as follows:

  • A chalet for 8 people, 4 bedrooms, 3 bathrooms (bathroom), an indoor sauna and an outdoor jacuzzi, 145m² of living space, in a middle area of Chamonix Mont Blanc, with a cosy decor;
  • A chalet for 14 people, 7 bedrooms, 6 bathrooms, 325m² of living space, wellness facilities, a living room arranged for large group meetings (family reunions or professional events) in a high-demand area, near the ski slopes, with high-end finishes and decor.

Thanks to these case studies, we can conclude:

  • Regardless of the commune in Chamonix-Mont-Blanc, the price of building a mid-range chalet sleeping 8 will average between €900,000 and €1 million.
  • The cost of building a larger chalet in a sought-after area (usually at the foot of the slopes) is closer to €2.5 to €3.5 million. However, it is possible to find more affordable land in Les Bossons, and so envisage a building project costing less than €2 million.
