French property buyers now prioritise thermal comfort over south-facing views amid heatwaves
As heatwaves recur across France, home buyers are increasingly judging properties by how well they stay cool rather than by traditionally desirable south-facing exposure. A survey shows most French people feel discomfort from heat at home, and one in three would consider moving because of it.
Repeated summer heatwaves in France are reshaping how people choose their next home, with buyers at viewings now asking whether a space will even be livable during the hottest months. In Paris, a man considering a 14-square-metre studio flat says he wonders whether he'll be able to live comfortably there between May and October, or whether he too will have to flee the heat like everyone else.
South-facing exposure loses its shine
A property's orientation, once considered a clear advantage, is now being judged on how well it helps keep a home cool. Estate agent Joseph Denke of FredéLion says south-facing properties are becoming less sought after, as buyers realise the sun beats down harder on that side. At viewings, people now focus on features such as through-layouts that allow airflow, the ability to air the home at night, shutters, terraces or shaded outdoor areas — some even consider whether there are trees nearby.
Air conditioning becomes a selling point
Air conditioning, rarely mentioned in listings in the past, has become a genuine selling point. Laetitia Caron, managing director of PAP (Particulier à particulier), says sellers used to overlook features like shutters or air conditioning, but now these are prominently highlighted. This shift is already affecting sales: in Paris's 5th arrondissement, a 66-square-metre flat with large windows has struggled to sell because it lacks dual-aspect airflow, leaving occupants feeling stifled, according to estate agent Christian Tokoto of Guy Hoquet, who says installing air conditioning is the only real fix.
One in three would consider relocating
A Leboncoin survey titled "Canicule & Immobilier 2026", based on 1,752 respondents, found that 81% of French people report discomfort from high indoor temperatures, and one in three could consider moving house because of heatwaves. Sophie Bourg, marketing director at Leboncoin Immobilier, says heatwaves are no longer viewed as isolated events but are now factored into housing decisions, with coolness and summer comfort becoming a standalone property criterion.
