Renovation Budget for a Flat or Chalet: Tarentaise, Tignes, La Rosière
Renovating a property (flat or chalet) in the mountains, especially in world-class resorts like Tignes, Val d’Isère, or La Rosière, is a unique project. Whether you want to modernise a family chalet or optimise a ski-in/ski-out flat for the rental market, the question of budget is central.
In the Haute-Tarentaise region, renovation costs are influenced by specific mountain constraints: high-altitude logistics, seasonal availability of tradespeople, and the use of noble materials.
Here is a breakdown to help you estimate the cost of your renovation project in Savoie.

Renovation Budget for a Flat or Chalet: Tarentaise, Tignes, La Rosière
1- Estimating the budget by type of renovation
At Hekta, we approach every renovation as a holistic experience. We distinguish between the extent of the property’s transformation and the level of service provided, so that we can offer a structured, clear and fully tailored approach to your project, whether it’s a second home or a rental investment.
Above all, we focus on identifying the best possible options and optimisations to stay within the budget set at the outset; the price ranges presented in this article are therefore provided for guidance only, as renovation costs can vary significantly depending on the technical and aesthetic choices and the specific constraints of each project, with no standard pricing structure applicable.
>> Refreshing and Interior Decoration
A light refurbishment enhances a property’s aesthetic without altering its layout or structure. By focusing on decor and surface updates rather than technical works, it modernises the atmosphere at a lower cost. While it boosts immediate appeal, its impact on long-term value is more limited compared to a full space optimisation.
Standard Renovation
Estimated budget: £800 to £1,200 per m²
This is a “surface” renovation aimed at modernising the aesthetic of your property without touching the structure or main systems.
– Updating wall and floor coverings (parquet, stone tiles).
– Replacing light fixtures and furniture.
Premium renovation
Estimated budget: £1,500 to £2,500 per m²
This involves a complete overhaul of the interior to improve comfort and energy performance.
– Full renovation of the kitchen and bathrooms.
– Upgrading electrical and plumbing systems to current standards.
– Modifying internal partitions to improve flow.
The Hekta advantage: Optimising the “Alpine cocoon” atmosphere with noble textures to increase immediate rental appeal.


>> Estimating an Heavy or Prestige Renovation
A complete renovation redefines your property from the ground up. By rethinking volumes, flow, and aesthetics, we transform each space into a coherent and high-performing living environment. While it requires a larger budget for structural, electrical, and plumbing overhauls, this ambitious approach significantly increases both the property’s market value and its emotional appeal.
Standard Renovation
Estimated budget: £2,000 to £3,000 per m²
It enables a complete transformation of the property, with meticulous optimisation of the spaces, technical upgrades and a significant improvement in quality, all carried out in a controlled and coherent manner.
Premium renovation
Estimated budget: From £3,000 per m²
For high-end chalets or luxury flats, this involves structural work and bespoke finishes.
– Structural modifications (removing load-bearing walls, creating openings).
– Installation of high-tech equipment (Home Automation, Smart Heating).
– Use of prestigious materials: solid oak, local stone, and Arpin wool fabrics.
– Creation of wellness areas (Sauna, Spa).


2. Factors influencing the cost in the Tarentaise
Geographical location and altitude
Renovating at 2100m (Tignes) is not the same as in the valley. High altitude implies:
– Increased logistics and delivery costs.
– Specific constraints related to snow and weather conditions.
Work windows (Inter-season)
In resorts like La Rosière or Tignes, work is mainly carried out during the “inter-season” (Spring and Autumn). This concentration of demand can impact the availability and rates of local tradespeople.
Bespoke Joinery and Layouts
To maximise space in mountain flats, bespoke “cabin” beds or integrated storage are often essential. This high-precision work, while more expensive than standard furniture, significantly increases the property’s value.
