Passive Solar Greenhouse Construction

Next, I began to stand up the perimeter walls. I am using treated lumber for the framing in order to prevent rot due to interior moisture and prevent rot. The treated lumber will be inside the finished walls except for the upper rafters and joists which will be painted. Here’s a few photos:
Here is a picture of the way I assembled the side walls working alone. I simply placed a couple of saw horses to support the top plate until I got a few studs nailed on. The distance between the window openings is really tight side to side in order to make the finished front trim look nice.
After the walls were up, I added some double 2″x10″ joists that I cantilevered to support an upper center wall and attic pathway. I’ll use the pathway to open and close the vent windows twice a year:
Then I stood up some upper support walls….not fun to do alone!
The rear rafters were then installed, and a metal roof added. The solid metal roof prevents the sunlight entering during the summer months. The clear roof glazing area is along the front half, south facing growing area.
The fellows that installed the metal for me commented about how stout the roof was they were on! Made my day.
