In Belgium, we are living in a small house with roof insulation while renovating the main house.
The small house gets up to 32 degrees inside when it is 34 outside as it has little thermal mass and is not sealed as it is an old stone atelier. We have to sleep in 30+ heat regularly during heat waves.
Main house is better insulated. We resorted to blankets over the southern windows and it is around 26 inside without us living in it at all (windows open at night and shut during the day). When we shift to moving there, it will be warmer. We would have to spend 45 000€ to insulate the walls + 10 000€ for roll shutters. Heat pump is the next best option coming in at a small fraction of that.
That is because your house is well insulated.

I’ve lived in two badly insulated houses and they stayed amazingly cool. Thick stone walls, baybee.
