What Goes into Every Cedar-Built Greenhouse?
Every kit is framed in premium Canadian Western Red Cedar — that's what makes it a Cedar-Built. From there, you choose your glazing: standard 6 mm polycarbonate or choose our optional clear plexiglass.
THE GREENHOUSE ITSELF
Highest Grade Clear Canadian Western Red Cedar
The cedar frame isn't a feature — it's the greenhouse. Every post, rafter, and beam is cut from the highest grade, knot-free Canadian Western Red Cedar. This isn't a cosmetic choice. Cedar is one of the only structural woods that genuinely thrives in the constant heat and humidity a greenhouse produces.
Decay & insect resistant
.Naturally resists moisture, rot, and fungal decay — perfect for the relentless humidity inside a greenhouse
Best insulating wood available
Cedar has one of the lowest thermal conductivity values of any structural wood, helping keep temperatures stable year-round.
Knot-free, clear grade
No knots, no checks, no weak points. Every piece is straight-grained and structurally consistent from end to end.
Built to last decades
Properly maintained cedar structures last 30–50 years. This is an heirloom, not a seasonal purchase.
Naturally beautiful
Warm honey tones and tight grain that age gracefully. No paint needed — just oil if you want to keep the colour.
BC sourced
The finest Western Red Cedar in the world comes from sustainably managed BC forests.

"“I love the clear plexi‑glass sidewalls. I wanted something beautiful and practical for my family, and with two boys playing sports, durability mattered. Plenty of wiffle balls and baseballs have hit it and it’s never been damaged. I look forward to many happy years in my greenhouse.” — Sheila, Manchester, NH (8×12)
