building a greenhouse

***We used old house windows from our friend (note, be cautious not to use windows with UV protection). We based our plans off the dimensions of the windows. I did have help with this entire build from my Dad.

Step 6: We layed one of the small sides down and began to frame the window in. We did not attach the window into the frame at this point.

Step 8: Then we repeated the process on the other side. (We had one door that will open and one that will be stationary.)

Step 9: We prepared the ground where the greenhouse would sit. Starting with a shallow trench we then leveled it out using sand. The sand made it a little easier to level the ground instead of the hard dirt.

Step 10: Next we moved the big wall and one of the small walls into place. We attached them together using corner brackets and then attached the side wall to the barn using 4 inch screws.

Step 12: Next we constructed the roof. We found a suitable pitch where a 2 x 4 could be adhered to the barn. We attached a board to the barn that stretched between the two short sides. We cut a support riser for both sides that reached from the top of the short side to the bottom of the board and attached it to the barn. We next found the angle for the pitch of our roof.

Step 13: We used corrugated plastic for the roof that was 23 ½ inches wide. To facilitate an overlap of the roofing we positioned the rafters so that the material could be screwed into the wood. You can also see additional supports between the rafters.

Step 14: We cut a piece of corrugated plastic to fit over the triangle that was made by the short side and the roof. We did this on both of the short sides.

Step 17: Next we filled the gaps on the short sides, that were left from the window and door, with more corrugated plastic.
