Premier Buildings of NW Montana · Columbia Falls
Finally in Montana.
The world's most popular greenhouse is here.
All Montanans have winter survival stories. This winter, make yours the one where the tomatoes made it to March. A few are on the lot. When they are gone, they are gone.
Built stronger. Lasts longer.
Grows better
Heavier steel, thicker panels, and a shape that sheds weather. Here is what that means for how long it lasts in a Montana yard.
50%
Stronger frame
3.07" heavy-duty galvanized steel is 50% stronger than typical galvanized, 2x stronger than aluminum. Built to hold up for a decade, not just a few seasons.
70%
Stronger panels
1/4" double-wall polycarbonate, 70% stronger than standard single-wall. Blocks UV, retains heat, and resists yellowing or cracking for years.
65 mph
Weather tested
Engineered to handle 65 mph winds and 3 feet of snow (32 psf). The arched design lets wind, snow, and hail slide right off. Grow year-round in any climate.
Why polycarbonate, why here
Why is this the right greenhouse for Montana?
Over 500,000 shipped across the US, Canada, and Europe, with the same arched design holding up through 15+ years of hard winters, windstorms, and summer heat. It's engineered for durability over looks, which is why it keeps standing when cheaper kits give out.
Sheds snow by shape
Rated for 3 feet of snow (32 psf). On an arch, snow slides off instead of sitting on the roof.
Stands up to 65 mph wind
Galvanized steel frame and 14-inch ground anchors. Wind slides around the arch instead of hitting it flat.
Hail bounces off
Twin-wall polycarbonate flexes on impact instead of cracking. Hail and debris just bounce off, year after year.
Holds heat when it is -4°F
Two walls with a layer of air between them, like an insulated mug for your plants. Cuts heating costs by up to 40%.
Blocks 99% of UV
Even, diffused light in high summer. The panels stay clear for years, no fading, no brittleness.

Same greenhouse.
Every Montana season.
From -4°F to 104°F, designed to keep doing its job whether you're in Columbia Falls or in Billings.
Cold climate
Grow through the winter
The double-wall panels trap a layer of air between them, like an insulated mug for your plants. That holds heat in and can cut heating costs by up to 40%, so you can keep greens going well past the first frost and through the coldest months.
Hot climate
Works in July heat, too
Our polycarbonate panels block 99% of UV and diffuse harsh light, so plants get even, gentle sun instead of scorching. The panels stay clear and intact for years, with no fading or brittleness. Two manual windows and an optional auto vent keep temperatures stable when it's 95°F outside.
Windy regions
Handles 65 mph gusts
The rounded roof is there for a reason: wind slides around it instead of hitting it flat. The polycarbonate panels flex under impact instead of cracking, and the galvanized-steel frame holds firm through storm after storm.

What customers say
Built it solo at 68
We got our greenhouse last spring. I am sixty eight years old, and other than holding and starting screws by my wife, I built it by myself. Easy, but time consuming. It's complete and we love it.

Passed city code in the Midwest
It's the only one that would meet the requirements for the city, meeting 65 mile an hour wind loads and 3 feet of snow! Perfect for the Midwest! It was easy to assemble as well!
Misti FriedlFeb 2025
Cucumbers and tomatoes went crazy
We built it with our grandkids most of the time, so it took us six weeks to complete. The plants that were started and put inside went crazy. They loved the atmosphere and produced huge amounts of cucumbers and tomatoes. Bruno's always available to answer questions.

Why we build these
We started making greenhouses because the ones we bought kept falling down
Gustavs built his first greenhouse with his dad, after two store-bought kits didn't survive the winter. That memory stayed with him. We build greenhouses so more families can put food on the table from their own backyard, instead of depending on the store.
So we started making them properly. Heavier frames. Real tempered glass. Warranties we'd still honor a decade later.
