Back Forty Building Co.

Back Forty Building Co. in Florence, Montana specializes in barndominium and rural home design rather than swinging hammers. The company sells construction-ready plans designed by people who are barndominium owners and builders themselves, and its site cites more than 2,750 custom plans created, projects built in 48 states, and over 12 million square feet designed.

Clients choose from 3 paths: buy a stock plan as the most economical route, modify a stock plan to adjust layout or room sizes, or commission a fully custom design with a high-touch process. The stock library includes plans such as the MR Post-Frame Collection plus single story, two story, and multi-generational layouts, ranging from a 1,661 square foot 3-bedroom up to a 6,169 square foot 6-bedroom. Beyond drawings, the site maintains contractor and materials resources and runs project referral pages for several building companies, which helps plan buyers connect design to construction.

A featured case study describes an Oklahoma family that self-contracted much of a 5-bedroom barndominium build from Back Forty plans. The site states that 96 percent of clients recommend the company. For owner-builders and buyers working with a separate contractor, Back Forty supplies the buildable plan set the project starts from.
