Add Shade, Structure, and Style to Any Outdoor Space
Pergolas, Gazebos & Arbors in Montana
Custom-Built, Not Kit-Built
What Sets Our Pergolas and Gazebos Apart
We build every pergola, arbor, and gazebo from scratch no flimsy kits, no one-size-fits-all templates. Each structure is custom-designed to your site, your aesthetic, and your goals. We use snow-rated hardware, moisture-resistant lumber or composite, and framing techniques proven in Montana’s harshest weather. Whether attached to a deck or freestanding in your yard, our builds are as durable as they are beautiful.
Shade Where You Want It, Style That Stands Out
Popular Uses for Pergolas, Gazebos & Arbors
Each structure we build serves a purpose and adds a touch of craftsmanship to your landscape. Pergolas provide filtered shade over patios or decks. Gazebos create freestanding seating areas for gathering, dining, or relaxing. Arbors frame walkways, garden entries, or fences with vertical charm. Whether you’re looking to define a space or soften it, we’ll help you find the right solution.
Pergolas over decks, patios, or hot tubs
Gazebos for backyard seating or entertainment
Arbors for garden pathways and entry points
We Build for Shade, Strength, and Aesthetic Value
Framed, Anchored, and Built for Montana’s Climate
We don’t just assemble shade structures we engineer them. Every pergola, gazebo, and arbor is anchored with frost-depth footings or secure deck mounts, depending on its location. We use pressure-treated or cedar framing, rust-resistant hardware, and design elements that shed snow while adding style. These aren’t just accents they’re lasting, load-rated structures built to perform.
Cedar, Composite, or Metal We Build What Fits
Material Options That Match Your Style and Maintenance Goals
Looking for natural wood charm or low-maintenance performance? We offer pergolas, arbors, and gazebos in cedar, pressure-treated pine, painted or stained finishes, and composite or metal options. Cedar is great for rustic elegance; composite lasts longer with less upkeep. No matter what you choose, we finish it to look clean, match your home, and survive Montana’s UV, snow, and wind exposure.
We Handle Design, Engineering & Permitting
Turnkey Outdoor Structure Builds Across Montana
From the first layout sketch to the last screw, we manage every step of your project. Whether it’s a standalone garden arbor or a 16x16 cedar pergola over a patio, we pull permits, engineer the frame, and build it to local code. If you’re in a HOA or hillside lot, we factor that in too. The result? A safe, stable, and stunning structure ready for year-round enjoyment.

Montana Conditions? No Problem.
Shade Structures Built for Elevation and Weather Extremes
In Montana, outdoor structures have to work harder. We account for snow load, frost depth, wind pressure, and solar exposure in every build. That means deeper posts, better bracing, and hardware that won’t rust. Whether your project sits in full sun or open field, we’ll build a pergola, gazebo, or arbor that stays put and looks great doing it.
Montana Pergola, Gazebo & Arbor FAQs
Everything You Want to Know About Outdoor Structures
Thinking about adding shade, style, or structure to your yard? Here’s what Montana homeowners ask most.
Can a pergola hold up to snow?
Yes ours are engineered for local snow load requirements and built with angled rafters for runoff.
What’s the difference between a pergola and gazebo?
Pergolas are open-top with beams for partial shade. Gazebos have full roofs and are often enclosed or screened.
Do I need a permit?
Most structures over a certain size or height do require permits. We’ll handle all of that for you.
Can I add lighting or plants to my pergola or arbor?
Absolutely. We pre-plan for lighting, fans, and hanging garden features.
