40×40 Barndominium Kits

If you’re looking to start building your barndominium, one of the first things to do is to get a quote for the metal shell or barndominium kit. By using the quote service below, you’ll get connected with a barndominium kit provider within a few hours at most. Prefabricated barndominium kits mean that the metal shell that makes up your barndo is produced off-site, then it’s brough to you for erection and assembly. While some builders will help you order the barndominium kit, we suggest doing it separately to avoid a potential markup on the barndominium kit.

That’s it! By using the tool above you’ll get connected with a kit provider for 40×40 barndominium kits.

We love how this floor plan maximizes the total floor area by placing the common areas on the right half of the home, and the bedrooms to the left half.

You walk into a spacious living room with the dining room right behind it and the kitchen farther in. All three common spaces are laid out in a linear fashion. When entertaining guests in the living room, privacy is ensured by keeping access to the bedrooms solely through the dining room.

Speaking of bedrooms, this barndo houses one master bedroom with a master bathroom and walk-in closet. One bedroom is big enough to accommodate two kids, while another bedroom is perfectly sized for one child. These 2 bedrooms share one bathroom.
