When my wife and I bought our first house, the first remodel we did was to put in more walls. We didn’t like the open plan with living, dining, and family rooms all separated only by one pass-through counter. We wanted privacy between the rooms. Our son could practice his trombone in his bedroom while our daughter practiced the piano in the living room while the dishwasher and kitchen fan ran, and while my wife and I watched TV in the family room without anyone bothering anyone else. It worked great.
When we were considering another remodel years later the several architects and designers who came to bid looked askance at the design and recommended opening up the walls for aesthetic or stylistic reasons. Apparently we weren’t cool. Or maybe we’re just tasteless clods. We said no.
My wife just heard a podcast about changes the Covid-19 stay-at-home orders have caused. It seems designers and contractors are getting a lot of calls for sticking in walls to close off those cool open plan designs once construction can start up again. Six or eight weeks cooped up in the house with the kids 24 hours a day (or maybe just with the spouse) changes your outlook. I feel vindicated and can’t help crowing just a bit. We were just ahead of our time.
