I love it and I manage my expectations: there will always be something I want but it will always have drawbacks so I'm choosing to be happy.
We could buy bigger. Pros are obviously space, easier to host and possibly equity in future.
Cons are cost, extra cleaning, less money for fancier life now (currently we could go abroad every summer without thinking about it). Getting more space also means a longer commute for everyone for work and school and may write off DD being able to walk to secondary which I think is important for her independence.
It would also probably be a temporary home until DD chooses a permanent location to live as an adult, at which point we would move anyway. We are also not really committing to UK. Considering selling and travelling in early retirement to dispose of assets early.
We also have the weird factor of having the smallest house out of our friends but the biggest out of our families, so sizing up would mean our "big house" would suddenly scream mansion money to our family (which is practical and still a normal house but embarrassing to me)
Not committing money now means we have more choices of e.g. private school or moving catchment or just buying DD a house when she is ready, so upgrading isn't the previous choice right now.
Plus I love our house. It is a perfectly good size, we just can't e.g. have chickens now! But chickens come woth outdoor cleaning and so the cycle of procrastination continues!
