Built to Withstand the Harshest Weather — Proven by Our Clients
Our timber‑frame greenhouses are engineered for demanding climates. Each kit arrives prefabricated, and the components simply screw together on site. The structure uses true 4×4 post‑and‑beam construction with interior support posts and a rigid 3‑ply main roof beam for exceptional strength.
This design performs extremely well in high‑wind and heavy‑snow regions, with installations across coastal Alaska, the Canadian Great Lakes snowbelt, Whistler, Lake Tahoe, and other extreme‑weather locations—where clients consistently report outstanding durability.
“With winds over 130 mph during Hurricane Gustav, I expected to see my greenhouse destroyed. When we returned, nothing had moved. Even my neighbors were shocked it was still standing.” — R., Houma, LA(14x24)
““You’ll be happy to know the greenhouse took the full brunt of the storm. In the 2022 Ottawa wind event—equivalent to an EF‑2 with 190 km/hr winds—huge trees were uprooted just feet away, yet nothing in the greenhouse was touched. Even the plants were perfect.” — N. Jolin (8×8)”
“We had another day with 100+ winds… the greenhouse withstood it and we are very happy about that!” Boulder, CO
“We have had 3 storms with winds exceeding 50 mph, 2 snowstorms with 8 inches each. It withstood these conditions without any difficulty” Lake Tahoe
“Missouri weather swings from below‑zero blizzards to 100‑degree summers with tornadoes and storms. Just wanted to say THANKS — it’s been a joy dealing with y’all!” — R. McClure (8×10)
“Our greenhouse is fighting the elements of whatever comes our way. Surprisingly, with a few nights of -13°C, our roses and geraniums have survived with no heat!” - M. Thiffault (8x12) Nova Scotia, Canada
“I am extremely pleased with the quality of the greenhouse, the beauty of the wood is incredible! The instructions were easy enough for us to follow. We had no difficulty. Godzilla (our biggest dog) 'supervised' the construction and spends a lot of time in the greenhouse with me. I've even moved one of his beds in there so he can be comfortable. I would have no hesitation recommending your company to anyone thinking of building a greenhouse. In fact, I already have!" Marie’s longhouse. PA (12x30)
"During the winter I have a HID light that goes back and forth on a track. I had it on an for five hours after it got dark each night during daylight savings time. We had carrots, lettuce, pole beans, bush beans, basil, and a tomato plant. "We have been enjoying the vegetables of our labors for two winters now. Around Christmas time, the scarlet runner beans were flowering. There is nothing like fresh beans in December and the greenhouse buried under snow! A. Rowland (12x12 Lean-To)
“The snow during the winter didn't cause any problems at all.”
"I spent a great deal of time researching, before I decided to purchase a Cedar-Built and I know I made the right choice. My GH certainly has extended my growing season in NH. Working in my GH is no work at all. It is a pleasure. It is so pretty inside and out. It is both therapeutic as well as a wonderful-looking addition to my backyard. This GH is so well constructed and sturdy and of the highest quality.” Sincerely, S. Wickey (8x12, NH)
