I used to work at Foltz Buildings Inc. which specializes in post frame construction, during the time that I worked there 8yrs. we built 12 post frame houses. I started up my own construction company last year with a partner, who also worked at Foltz Buildings for 18yrs. We have now built a post frame house in Audubon Mn and are now in the process in building another post frame house in Vergas Mn. There are not any plans or blue prints available on these types of houses yet, but if you contact me or cleary buildings who also builds post frame houses you should have your questions ansered
