We currently live in 1,750 square foot house. It feels like WAY too much space - we keep our belongings pretty light, and 95% of our time is spent on the first floor which is <900 of the total space.

We are looking at two potential home options if we move, one is 1,650 and other 1,300 square feet - basically same floor plan with open kitchen and living room and rooms off sides, one story.

I am perfectly happy with the 1,300 one and have preference for cozy spaces. Would I majorly regret it once we have a kid?

This would be a 5-6 year house and over 40% cheaper than current one, then build our own.
