Here's an article at Knoxvillebiz.com about a couple ordering the $75,000 one bedroom core ihouse, and adding $100,000 of upgrades to it, including things like "automatic sliding doors."
From the architectural form of the exterior, I prefer the one bedroom to the two bedroom, and it is nice to see someone with an unlimited budget buying one.
If anything, this shows Clayton's willingness to customize, for a price. You can see more photos of it on Clayton's FACEBOOK page HERE, as well as some nice snowy winter photos of an i-house with LARGE flex room in Virginia.
The article has some other interesting tidbits too.
Apparently, Clayton's hotcakes are still soldered to the griddle, holding at only 20 ihouses sold.
