My house is 90m², though the upstairs has a low ceiling and mostly just functions as a bedroom, so it’s more like 60m² in practice. While I wouldn’t want to raise a family here, I still find it perfectly sufficient for two people. It also comes with the additional benefits of having fewer rooms to heat, clean, and renovate. I also like that my yard feels a lot bigger due to the smaller footprint of the house itself.

That being said, I would prefer it to be slightly bigger. Maybe one extra room and a bigger-than-1.5m x 1.5m bathroom.
