The wall are constructed using really basic construction methods. I spaced the studs 24" on center.

Once i had four walls I stood them up and connected them together. I used clamps to hold everything in place while standing them up.

The roof is made up of three triangular supports that 2x4'rafters' are connected to.

I got some help from some friends to lift the roof into place once it was built. I used screws to attach it to the rest of the frame.

The shelf system (more info in video) is tied into the studs to make everything more sturdy.

There are definitely cheaper options, but I chose to use clear corrugated panels.

Thanks a lot or checking out the project. Obviously this was a really big project and hard to fit into a photo slideshow, so be sure and check out the video and written article on RyobiNation.

    How hot does it get I the summer months?

      I have a green house that I bought 2 years ago. It is solid for the winter. I go to my summer camp twice during the winter to unload the roof full of snow.
      Concerning your question I notices that when it's 62 F and sunny the temperature goes up to 110 F. Very hot. I open the door and the window that is on the roof. When I have to leave for a couple of days I transfer all my plants in an old Canvas Garage that I had bought for my car during winter and I find it better to use during the summer. There is a difference of about 14 F lower in my old garage. The plants are beautiful and I, already, have 5 small tomatoe

      Since we live in Texas, I would definitely want a simple foundation and four straps all the way over the roof and back to the foundation. I would probably want either blue or green on the roof, even if I had to paint one coat of paint to block some of the summer heat. I'm short, so I would want two flaps lower down that I could I could tie from inside for cross-ventilation. Since I would not leave a lantern burning all night in the winter, I would run a weather-resistant electric line so I could turn one or two lights on when needed. The video shows some important construction basics, too. Best wishes 😇

    Do you have some way of closing off the rippled openings where the edges of the corrogated panels meet the frame? I'm thinking mainly to keep the bugs out, but in colder areas, to limit ventilation when needed.

      The lumber yards sell strips to fit these edges.

      Thanks for answering so quickly. Great to know there's something meant for those openings.

    Very nice - I love my greenhouse , but it has crashed 3x due to snow. any idea how much of a snow load yours could take?

    • Lisa Vanbeselaere
      on Jul 14, 2017

      Don't know what the snow load would be, but by the diagram the pitch of the roof is 12/12. I have also had panels on my greenhouse collapsed due to snow, but our house has a pitch of 12/12 and it never has snow on it. 12/12 pitch roof is used in high snow areas, like the mountains chalets.

      One could also put on a tin roof. Tin for strength and tin also creates heat.

    Oh, I'd love to make this for a cute little tool shed. I love how simply you put it together, using tools everyone has. Now what would be the best way to prevent termites?

    As a native Texan, I curious--did you anchor it to the ground in case of tornadoes or high wind?

    Love this, BTW! A friend and I have been talking about greenhouses all week!

    do you plan on heating it in the winter? I would love to have a place for my house plants in the winter, but in Midssouri, would have to heat.

    How many 2x4s did you use? What is your material list?
