If you are having alot of builtins make sure you don't cover up needed outlets. My sewing rm is 27 x 30 and i knew my midarm was going to be near the center of the rm for ease of putting on quilts so in the ceiling I have drop down extension cords (from Sears) just like my DH has in his wood work shop. I use it for my ironing board as well. So nice, out of the way, just reach up and pull down.
