Our old house was a 3 bed detached and was 900 square feet , when it was just my wife and I it felt ok size wise , eventually though it felt to small especially after my daughter came along.
we have to a 4 bed detached which is approx 1900 square feet , for first 12-18 months it felt massive and often a few rooms were empty while we bought more funiture and things etc.
I am now at a point where I think the house is starting to feel small. It’s the 3 of us and a cat. It doesn’t feel small all the time just every now and then. When I think rationally I know it’s silly. While there are tons of much bigger houses out there I often wonder if over time do all houses start to feel smaller after a while?
