I can’t say I regret buying our house — which doesn’t have a single dividing wall on the entire main level, other than around the bathroom — because it worked well for us when we had babies and toddlers. In those days, I needed to be able to watch the kids closely at all times — even when I was ducking into the kitchen to empty the dishwasher.
Now that they’re six and eight, I feel a longing for one particular house we toured. It was really old and had lots of little rooms, all separated by hallways and doors. I’d scoffed at the closed-off kitchen at the time, but now I think it would be nice to shut myself in there and listen to music quietly while I make dinner … without hearing the TV blasting from 15 feet away.
Anyway, the other issue with an open-concept house is that you can’t easily transition to different paint colours because the whole level is all connected. No walls. No doorways. Just … openness!
