Since this old blog post of mine is referenced high in Google's search results, I'd like to remind readers I've made dozens of other posts about the i-house since 2008 which can be found in the BLOG ARCHIVE index on the right of this page.
Link to my July 2009 video of i-house model (2-bedrm core+flex)in Albuquerque.
Link to better resolution photos, I took, on Flickr.
Clayton has a separate site just for the i-house. You can find it by Googling:
Clayton i house
(Their official site should be in the top five or so.)
