I have less than a year ago. Old house was 3000 sqft, 5 bedrooms the smallest was 14x18, large finished basement, huge laundry room for sorting and folding laundry, 3/4 acre mostly grass lot with a few trees and big flower beds, 3 full bathrooms, you get the idea.
New house is smaller, about 2100 sqft 600 sqft unfinished basement so the house could be bigger, 4 bedrooms the smallest is 12x12, 2.5 baths, small city lot, laundry "room" is the entry way into the garage so no room for sorting folding. Very open floor plan, with a loft so lots less wall space for pictures.
The consensus, we like it better. Cleaning 3 bathrooms sucks, we only had beds in four of the rooms before and now (two kids and a guest room). The kids had e basement for their area before, now they have the loft. We didn't have a formal living or dining room before nor now so no loss. Smaller nicer more manageable lot now.
Sacrifices on pictures had to be made, my signed Jack Brabbem, Villeneuve (2), Schumacher, and Phil Hill prints aren't up (yet) as we have less wall space. We don't have extra room that is liveable but not used. All the usable room is what we use on a daily basis except the guest room and office. Best of all, went from a two car garage with two one car doors, to a three car garage.
So would we do it again? Yes, maybe not this area, but would sacrifice the house size
Neighbors, we had them before but the way the house was, none in back, none directly across the street, and the ones on each side was set so we couldn't see them looking out the windows at the angles we did.
Here, someone directly behind us, directly across the street, but our house is at the end so nobody on one side. We got used tonit pretty fast.
