How to Build a Greenhouse | Post and Beam

Make your own Post & Beam Greenhouse with twin wall polycarbonate glazing and a poured concrete foundation. This timber frame style Western Red Cedar post & beam greenhouse has a base that's 10 feet by 12 feet. I cover all the carpentry and construction of this garden greenhouse starting with excavation, making the concrete forms and pouring the foundation. Then I move on to cutting, notching, and preparing the posts, beams, ties, and rafters. Followed by the assembly of the post and beam frame. Then I cut and install the twin wall polycarbonate glazing and install it on the walls and roof. There's also some custom cedar louvered vents and a fan for air circulation. Then I build and install a light-weight cedar door and finish the construction with a two part ridge cap for the roof. There will be a four part detailed follow up video series after this. I have a 14 page greenhouse plan that's available at the link below.

This is the clearest, best explained build project I've seen so far. The animation at the start is especially good.

As a contractor with over 40+ years of building experience myself, I must say, I am impressed with your build of this greenhouse. You've done an excellent job, and for a small greenhouse, it is not only very well built, it's beautiful as well. Your use of lap joints, dado's, handmade louvered vents, and all the other building methods used, including the use of stops and such, even the hand made forms for pouring the concrete foundation, would make anyone believe you were an experienced master builder. In this build, I see better building methods being utilized than in most of the homes today that people actually live in. End result is a gorgeous, functional greenhouse that will last for many years. Great job!

Kent, sometimes I think you get carried away on your projects, but I admire your attention to detail and the results it produces. Unfortunately, I watched this video while my wife sat behind me when suddenly I heard her say, "Yeah! Like that!"

I have to agree with the commenters—best construction video I’ve ever seen. Quite remarkable craftsmanship, indeed.

[matthewbarker]

This greenhouse is better built than most homes! It was lovely seeing your craftsmanship - thank you for the video.

As a 70 yo ret. Gen. contractor this greenhouse could withstand a nuclear blast. I love how you built this small greenhouse and used the members (beams and Posts) for structural strength not depending on the fasteners. Well done. Fasteners only hold the structural members from moving and the structural members still take the load. Very nice I like it.

I really appreciated the orderly way you explained. Quick schematic overview, then the steps. A beautiful greenhouse!

[DavidLawrenceDaley]

Dude, your very good at explaining calmly and eloquently

[tonywhitley]

I am watching this video again, and am still very appreciative. The "one-man" build and the scale of this project are perfect for a host of week-end warriors like myself.

[AHappyBachelor]

A great series of videos, thank you for taking the time to make and post them

[tatianagarces]

That was beautifully done, I could see myself trying to tackle this project when I’m ready to build a greenhouse. Thank you!

Best use of Sketchup I've seen to date.

[thackeray]

Absolutely beautiful! Your wife is a lucky woman!

[bostewart]

I've never seen such a concise, well explained, and well animated video like this on YT. It's perfect. Thank you. I'm going to the lumber store today to build this.

[deborahelliott]

by far the BEST video on a greenhouse build! I will save this and copy this for this upcoming SPRING!

[g.ijoebear]

Don't think I ever seen a more professional build from start to finish, every step impeccable prepared and executed. Very nice!

[louisecolombi]

You’re brilliant, skillful, and a communicator, a teacher. Thank you for your channel

[pennywilkins]

All of my projects are done 100% alone, I never have an extra set of hands to help. I learned so much watching your videos!! Great tricks for working solo!! AMAZING WORK!

[rtshchand]

Man!!!! you should be a teacher. Such a beautiful project with explanation of each step.
