A Home on a Post-Frame Structure
A pole barn home, often called a barndominium, is a post-frame building with living space inside. The same structure that makes pole barns efficient, posts carrying the load and trusses spanning wide, also makes open floor plans easy and puts a shop or garage under the same roof as the house.
We build the structural side of these homes around Bozeman, Belgrade, Livingston and Paradise Valley. Here’s what that covers, and what it doesn’t.
What We Build, and What We Don’t
Our work is the structure:
- Excavation and site prep, including clearing, grading and building the pad so water leaves the site
- The foundation or slab, formed and poured by our own concrete crew
- The post-frame shell: posts, trusses, roof and exterior walls
- Utility trenching for water and power lines below frost depth
Other licensed trades handle the inside. Plumbing, electrical, heating and cooling, and interior finish are done by the appropriate trades, hired by you or through your general contractor. Our job is to make sure the slab and frame are ready for them, so nobody is cutting new concrete to fix something that should have been planned.
Being clear about that split up front is what keeps a pole barn home from turning into a coordination problem halfway through.
Permits and Engineering Come First
A shop and a home are held to different standards. Living space brings residential building code, engineered plans that account for snow and wind loads, energy requirements, and on rural lots, water and wastewater approvals. Inside Bozeman city limits, out in Gallatin or Park County, and within individual subdivisions, the rules and covenants differ.
None of that is a reason not to build, but it does mean the plans and approvals come before the excavator. Talk to the building department early. Once the plans are set, we build the structure to them.
The Slab Decides More in a Home
In a shop, the floor drives a lot of decisions. In a home, it drives even more. Everything that goes in or under the slab has to be in place before the pour:
- Under-slab plumbing, set by your plumber and inspected where required
- In-floor heat tubing, placed by your heating contractor if you want radiant floors
- Under-slab and perimeter insulation, which matters enormously at a slab edge sitting against frozen Montana ground
- Vapor barrier, which can never be added after the pour
- Conduit and anything else that has to come up through the floor
Our guide to shop concrete floor decisions covers the same principles in detail, and they apply with more weight when people will live on the slab. Because we pour our own concrete, the slab is planned with the frame and scheduled so the trades can get their work in first.
Built for Montana Loads
The structure is designed for where you’re building, not a generic number:
- Snow load for your location, which varies a lot between the valley floor and the mountains around Big Sky
- Wind on open ground around Belgrade and the Gallatin Valley
- Frost protection for the foundation, so the building doesn’t heave. Our article on frost depth and footings explains why this matters here.
How the posts meet the foundation in a home is set by the engineered plans, and we build to them.
Plan the Shop Side Like a Shop
Most barndominiums include a shop or garage, and that side deserves the same planning as any pole barn: door height for the tallest thing you’ll ever bring in, slab thickness for what will drive on it, and clearance for a lift if one is ever possible. Our guide to sizing a pole barn walks through the questions in order.
Site, Access and Utilities
A home site needs year-round access, a pad that sheds water away from the building, and utilities brought in below frost depth. Our crews handle the excavation, the road or driveway in, and the utility trenching, so the site is ready for the structure and the structure is ready for the trades.
Where to Start
If you have plans or a designer, send them over and we’ll talk through the structural scope. If you’re earlier than that, tell us what you want under the roof, where the property is, and whether a shop is part of it, and we’ll explain what the structure will need.
