Easy

This is a cedar greenhouse I built last year in my yard .It is 10 ft wide by 11 1/2 ft long . I had some extra lumber laying around so this is what I decided to make :-)

I started by using 4 pressure treated 4x4s for the bottom plates of the frame .

I did half lap joints on the bottom of the frame .

The height of the walls are 6 ft .Once they were in place I plumbed them up and made sure everything is square and level .

next step was adding the main roof frame .

I added all the 4x4s afterwards once I knew how wide the plastic sheets were so it would be less cutting . I added cedar trim pieces so the plastic could be attached . I used 1 x 6 cedar for the bottom section .

I filled in the rest of the roof rafters then added the rest of the plastic .I also added 2 roof vents at the top of the roof .

I also added removable shelving to the inside of the green house .

Once the plastic was done I added the double door to the front .

    How do you open the vents that are mounted on the peak of the roof? They appear to be propped open but you would need to lower them at night or as the temperatures changed. Would vents on the end walls be more practical if I'm a vertically challenged person?

      Looks to be poles you lift to open and pull down to close. Side ones would be better. they can stay open even during rain.

      Its A SUMMER HOUSE !!!!! But you could hang hot lamps not close to plastic. Or small heaters. Better for spring ,summer, fall use. Winter would need glass use.
