I am absolutely not a fan of open concept -- when my DD was small she could be along in the living room while I was in the kitchen and I never did fret -- I didn't need her in my line of sight 24/7.

And I would not like people to come to the door and there is my kitchen with my dirty dishes stacked on the island because I got a telephone call and my guests were unexpected.

I get great delight on Sunday mornings when I take the house plan for the week and draw in "walls" -- making the living room a separate room, the kitchen all it's own space and a proper dining room. Some homes are easier than others for a few are the one big room with this corner living room, that corner for dining and that corner for the kitchen but it can be done!

It's my Sunday morning pleasure!
