Assuming you are in western Europe, I'd say for 140m2 it seems a bit more than okay, depending on how much windows you have. And depending how north you are. And depending on your usage (WFH, cooking...), it can be great.

I do have 9 windows, living room is the sliding one which is 2,5x4 meters. I rarely work from home, cooking almost every evening.
