Stairs SUCK, and that's the bottom line. My wife's parents have had a split level, and now a colonial. They're unloading the colonial now, because it's too much house to take care of. Climbing the stairs several times per day doesn't help. The house they're going to replace it with, will NOT have an upstairs!
I remember when I was dating my wife, they used to stack stuff on the stairs. I asked my wife why? She said that anybody going up, would grab an armful and take it with them, so that they wouldn't have to make unnecessary trips up and down. Slick, eh? :roll:
Stairs are the price you pay, for saving money on a larger foundation, and utility costs. There are pluses to building a 2 story, but those damn stairs just aren't worth it to me.
