I never understand the pull of open concept. If there is just one big room other than the bathrooms and bedrooms it makes it difficult to control noise and have any privacy. If I want to work on a computer, practice a musical instrument, or read a book I have to use a bedroom.
The only time you need one big room is for a party. It does make the house look bigger but not sure it is the best choice for most families.
My thoughts exactly. They say it’s so the mom can cook and keep an eye on the kids. Our house is anything but open concept, and I never managed to lose a toddler.
