Every property in Montana is different.
Your building should be too.
We offer a wide range of Amish-built styles that you can tailor to your land, your space, and the way you work or live. Whether you need extra height or a custom loft for storage, more natural light for gardening, or a cabin-style retreat in the woods, we will help you design something that fits your life.

All buildings are constructed using LP SmartSide siding, stain grade fir plywood or metal siding, 40-year metal roofing, and pressure treated skids with strong on-center framing and ¾ inch tongue and groove floors. These are the same materials trusted across Montana’s toughest climates.

Our Most Popular Building Styles

Animal Shelters

Built for real Montana livestock needs, these shelters are sturdy, practical, and made to last. Choose open or enclosed layouts with strong framing and weatherproof siding. Whether you have horses, cattle, goats, or smaller animals, each shelter is designed to keep them protected and comfortable. These look more like a small horse barn than a basic lean-to, and they hold up through every season.

Barns

Built for Montana’s climate and day-to-day lifestyle, our Hi-Side and Old West barns offer generous overhead loft space for hay, tools, tack, or seasonal gear. Use them for livestock, storage, or a rustic workspace on your property. Strong framing and classic Western design make these barns a dependable and good-looking choice for almost any need.

Cottages & Tiny Home Shells

Cozy, versatile, and ready for you to finish your own way. Start with a finished exterior, then turn the inside into a hunting cabin, home office, guest space, or the beginning of a future tiny home. A great option for rural properties, lake lots, and Montana getaways.

Garages

Designed to stand up to Montana weather, these garages keep your vehicles, ATVs, and projects protected during every season. Each prefab garage includes reinforced 12 inch on-center floors, insulated overhead doors, and solid framing that holds up to daily use.

Greenhouses

Bright, sturdy, and built for Montana’s growing seasons, our greenhouses are made with twin wall polycarbonate panels, built-in potting shelves or planter boxes, auto ventilation, and strong framing. Perfect for gardeners who want spring plants earlier, fresh herbs year-round, or a warm place to grow through the shoulder seasons.

Pavilions

A beautiful outdoor structure that brings people together. Use it to cover a patio, picnic area, hot tub, or backyard gathering space. Each pavilion features a classic timber-frame look and durable construction that handles Montana wind, snow, and changing seasons. A long-lasting way to add shade, structure, and charm to your property.

Sheds

A good shed should make your life easier and look like it belongs on your property. Choose your siding, colors, trim, roof pitch, and window layouts, then finish the inside with shelving or lofts for organized storage. Whether you want a she shed, a man cave, a workshop, or a simple place to store equipment, we will help you bring it to life.
