There's a manufacturer of round houses one hour north of me in Asheville, NC! I don't recommend them though. I have built round walls, for a Starbucks Coffee, if you can believe it, my first one. I estimate 5 times as much effort and time involved vs. a straight one! I use them sparingly because of that. But yes, I do like curves! Beauty is in the curve, I always say, there are no straight lines in nature. That's why us men like females!
