When we had 6 children, we moved half way across the country. We sold a 3300 square foot home and bought a 720 square foot (2 bedroom) mobile home. We lived in it for 6 years while we slowly built our home.
It was small and we are thankful for all the room we have now, but I liked not having clutter. The home just wasn’t big enough to have too much stuff, so it was easier to keep clean.
Our living room was about the same size as yours. What a blessing for you to add on!
