Open kitchens are often the norm in new houses or apartments, the assumption being that most people like to cook without feeling isolated from the action in the living room. But one of us here at the Kitchn is about to build a wall specifically to close off a kitchen...The wall will give us a better layout in our living room, providing a spot for a bookcase. But we are actually happy it will hide the kitchen from view.
We like being secluded while we cook. It helps us concentrate, allows us to make mistakes and cover them up without anyone knowing, and keeps our messes hidden. We also get a big ta-da moment when we emerge with finished dishes.
