We live in a small 3 bed terraced house in London which we were very lucky to be able to buy because it was by no means cheap. My older sister also lives in London but in a large semi with a big garden and four beds. She was a headteacher and her husband a solicitor and they only have one son, so they are very well to do. But I don’t envy her at all, I love my little house and wouldn’t want to live anywhere else, my sister is a widow now and feels increasingly lonely and stressed in such a big house that she finds hard to maintain.
I would never want a bigger house at my age, especially now that I care for my DH, and keeping the place tidy and clean is much more doable.
