Barndominium Floor Plans and Design in Montana

Built for Real Work

Every barndominium H&H builds starts with a conversation about how the structure needs to function. We do not offer pre-made plans or kit-based pole barn barndominiums. Each project is fully custom, designed around your land, priorities, and how you live in Montana.

H&H Custom Buildings is a family-owned company founded in 2005 by Al and Lucas Irvin in East Helena. Lucas leads every project. We serve property owners within about 90 minutes of Helena and take on a limited number of builds each year, ensuring each barndominium is designed specifically for the property and use case.

How Structure Impacts Your Barndominium Layout

The structural system is one of the first decisions that shapes your floor plan options. Post-frame construction uses engineered columns embedded in or anchored to a concrete foundation, which eliminates the need for interior load-bearing walls. That single characteristic opens up floor plan flexibility that conventional stick-frame construction cannot match at the same cost. It is why post-frame is a natural starting point for most barndominium living space designs.

Clear-Span Interiors Give You Real Design Freedom

Without load-bearing interior walls, your floor plan is almost entirely open within the exterior footprint. Wide great rooms, combined kitchen and dining areas, oversized garage bays, and open loft configurations all work because there is nothing structural in the way. You decide how the interior is divided. The framing system does not make that decision for you.

Lofts, Mezzanines, and Two-Story Configurations

Eave height is one of the most consequential early decisions in a barndominium build. A structure with 16 to 20 feet of eave clearance opens the door to sleeping lofts, recreation lofts, mezzanine storage, and full second-floor living configurations. These are not add-ons. They are a natural result of how post-frame pole barn living spaces are built when eave height is planned from the start.

Your Footprint Sets the Boundary. Your Interior Layout Does Not

The exterior dimensions, width by length, determine the total square footage you have to work with. Within that footprint, interior layout decisions are highly flexible. A 60×80 structure gives you 4,800 square feet. A 50×80 gives you 4,000. How that space is divided between living quarters, garage bays, shop space, and utility areas is a design decision, not a construction constraint.

Common Barndominium Layouts in Montana

The right layout depends on how you plan to use the structure and which needs to take priority. Here are the configurations H&H builds most often across Helena, East Helena, Bozeman, Townsend, Anaconda, and the surrounding region.

  • Open-Concept Living with Dedicated Bedroom Wings

    The most requested barndominium layout combines a large open kitchen, dining, and living area with a private bedroom wing on one end. A 50x80 footprint gives you room for a 1,200 sq ft open living area, a primary suite, two additional bedrooms, and a full utility room, all under one roofline. High ceilings and wide, clear spans make the living space feel significantly larger than the square footage alone suggests.

  • Shop-Forward Layouts with Living Quarters

    Buyers building primarily around a shop or garage need to dedicate 30 to 40 percent of the total footprint to living space and the remainder to vehicle bays, workspace, or equ
