You know, I look at the McMansions around here and just can't understand why anyone would want a ridiculously large house on a lot the size of a postage stamp. Man, I don't even want to think what it would cost to keep one of those places cool during a Sacramento summer.
MoneyHoney, if you like the Katrina cottages, you might want to look at
Tumbleweed Tiny Houses. Scroll down a bit for the roomier (a.k.a. 500 sq ft) models. I'm rather in love with the B-52 Bungalow.
