A 1960s house in South London is staying 10C cooler than outside without air conditioning during extreme heat. It acts like an insulated flask maintaining a cooler temperature indoors by keeping heat outside

As extreme heat becomes a growing problem for homes, one 1960s house in south London is showing how older properties can be adapted to handle hotter summers without relying entirely on air conditioning.

According to the BBC, Marion Baeli’s four-bedroom home was around 10C cooler indoors when temperatures outside reached 35C. Baeli, an architect, has spent more than a decade upgrading the property to improve its ability to deal with both summer heat and winter cold.
