South-facing orientation: how much does it change the value of a chalet?

Orientation is one of the least visible but most important criteria in the valuation of a mountain chalet. At altitude, the orientation of a property determines sunlight exposure, thermal comfort, the usability of terraces and — ultimately — the quality of life of its occupants. All of this has a price.

Why orientation matters more in the mountains than elsewhere

In the mountains, valleys are narrow and the surrounding massifs can cast shadows for much of the day in winter. A north-facing chalet in a narrow valley may receive only a few hours of sunlight per day in December and January.

Conversely, a chalet facing due south at altitude catches the sun from the morning, benefits from better natural light and has a terrace that can be used even in winter. These differences in comfort have a direct impact on resale value.

The value gap between south and north-facing properties

In the Mont-Blanc valley, the difference in value between comparable properties with opposing orientations is significant. Transactions observed by MOMA Real Estate suggest a differential of 10 to 20% between a due south-facing chalet and a property of the same size and condition but facing north.

This premium is explained by several cumulative factors: better thermal comfort (heating savings), a terrace usable in all seasons, better natural light quality for professional photography, and a clear preference among foreign buyers for well-oriented properties.

South-west and south-east: important nuances

Due south is not always the most advantageous: a south-west orientation benefits from sunny afternoons, ideal for an end-of-day terrace. A south-east orientation enjoys morning sun, desirable for breakfast outdoors. Both remain highly valued.

An east-north-east orientation, on the other hand, is the least desirable: limited sunshine and terraces in shadow for most of the day. The discount can reach 15 to 20% on otherwise similar properties.

Orientation and EPC: an often underestimated link

A well-oriented chalet requires less energy to reach a comfortable temperature in winter. This physical reality is sometimes reflected in better energy performance (a more favourable EPC rating), which itself contributes to the property's value in the current regulatory context.
