Pole Barns & Ag Buildings

Red barn with white trim and large sliding doors, surrounded by a grassy lawn and small shrubs, under a cloudy sky in the early evening.

At Montana Home Builders, we specialize in building durable, versatile agricultural structures designed to meet the needs of Montana’s landowners, farmers, and ranchers. Whether you’re looking for a roof-only shelter for livestock, a fully enclosed hay storage facility, a heavy-duty equipment garage, or a large commercial steel building, we can build exactly what you need—no limitations, no shortcuts. Our ag buildings are built to withstand Montana’s harsh weather, with quality materials and proven construction methods that ensure strength and longevity. From small detached garages to expansive machinery storage and custom livestock shelters, every structure is designed with function, budget, and long-term durability in mind.

One of the biggest differences in our construction process is how we set our posts. Unlike many builders, we never bury posts directly in the ground. Instead, we use above-ground mounting systems that eliminate the risk of long-term rot and decay, extending the life of your building and reducing the risk of costly repairs down the road. Whether you need a single-purpose pole barn or a multi-use agricultural building with office or storage space built in, we’ll help you plan and construct the right structure for your operation.

Our team brings years of experience in agricultural and rural construction, and we’re equipped to handle everything from simple shelters to fully customized steel buildings. If you need a reliable, cost-effective solution for your land or operation, we’re ready to build it.
