How-to Build a Post & Beam Greenhouse
Make your own Post & Beam Greenhouse with twin wall polycarbonate glazing and a concrete foundation! This Timber Frame Style, Western Red Cedar Post and Beam Greenhouse has a footprint that is 10 feet wide and 12 feet long.
This modern red cedar and fir structure uses simple joinery and easy to find hardware to construct in your backyard or garden. This plan is an 14 page pdf with fully dimensioned diagrams and construction and assembly instructions, printable on 8.5 x 11 size paper. Dimensions are in inches and millimeters and this plan is designed for actual lumber sizes like you would find at a local sawmill. The plans can be adapted for nominal lumber like you would find at a Big Box Hardware or Building Supply Store. These plans are for download and will not be mailed.

Very detailed plans. But my project is on hold.
I sent an email with a question but to this day, I never got a reply…..It’s to bad cause I had other of your projects in mind but no reply is end of story for me!
Hi Rheal,
My sincere apologies for not replying promptly. I got my sheets from a local supplier. Their website is https://www.greenhouseplastics.ca/ They may ship your way or direct you to another supplier of big sheets in your area. Try greenhouse suppliers or companies that install awnings or deck/porch coverings.
