My home here now is only about 50m. Good enough for what we need. Cramped compared to what I grew up living in. Lived in more than 12 homes growing up from birth to graduation. Dad did construction. Owned his own company. So our houses were always much nicer in build, layout and size.
In college dealt with a smaller living space. Both the dorm and later my own tiny apartment. But, soon as I got work and bought a house and went from there, all big again. Plan to stick to that when we return to the US in the nest 2-3 years.
That said, my dad, who always made, or bought smaller and added on after, large homes. My mother died, and when my dad remarried, my step-mom always grew up with nice big homes and lived in them when married to first husband. But now, they both sold all their homes over 9 years ago, and moved into a refinished/remoded cottage on Lake Michigan(turned it into an all seasons home) that is half the size of what either of their homes was. Then bought a motorhome and head to AZ every winter. So a nod to FastWalk on that. The motor home is half the size, at best, of their home now.
I find it entertaining how people rationalize the size of home they need. Dad sold 2 homes. One a 4 bed/3 bath home the other a 2 bed/1 bath. Step-mom a 5 bed/3 bath home. Now live in a 2 bed/2 bath half the year. A 1 bed/1 bath motorhome the other. They went from both believing they needed the large homes and all the furniture in them and having reasons for all of that, to a whole lot less and say they are happier now than they were then. I get a kick out of stuff like that.
