A barndominium shell provides the foundation for your future home while allowing you to complete the interior on your own timeline. At Superior Postframe, we design and construct custom barndominium shells throughout Western Montana using durable post-frame construction, metal roofing, and metal siding.
Our scope focuses on the exterior structure, giving you a strong, weather-resistant shell that is ready for interior finishing by you or your preferred contractor. Whether you’re planning a simple living space, a shop house, or a fully customized barndominium, we provide the structural framework to help bring your vision to life.
Barndominium Standard Features
Every barndominium shell is built with durable materials and proven post-frame construction methods to provide a strong, weather-resistant exterior structure. Superior Postframe focuses on the shell construction only, allowing homeowners to complete the interior build-out separately.
Post-Frame Construction
Your barndominium shell starts with a durable post-frame system that provides wide-open interior space, design flexibility, and long-term structural integrity.
Metal Roofing & Siding
Durable metal roofing and siding help protect the shell from Montana’s weather while providing a low-maintenance exterior finish built to last.
Fully Insulated Shell
Insulation is installed as part of the shell package and does not include interior framing, drywall, electrical, plumbing, HVAC, or other residential build-out work.

Flexible Foundation for Future Finishing
The open-span design of post-frame construction creates a versatile structure that can be configured to suit a wide variety of future floor plans. Whether you plan to finish the interior immediately or in phases over time, a barndominium shell provides the flexibility to build out the living space that works best for your needs.
