My dear hubby built me a greenhouse several years ago as my 25th wedding anniversary present. My hubby is a wonderful man BUT, he is an auto mechanic, not a carpenter. I went to my local library and checked out several books on greenhouses and how to build one. I settled on one that gave step by step instructions and we set about making our very own greenhouse. Some modifications had to be made due to what we could afford in terms of materials and what we had on hand. To start with we had 5 full sized sheets of glass from sliding glass doors and used those for the south wall and one sheet on the west wall. That gave us plenty of light. Following the books instructions we poured a ribbon of cement for the base then used a row of cinder blocks on top of that. We bolted the frame made from treated 2x4s. We made our own frames for the sheets of glass. This 3 sided structure was attached to the south side of our house. It measures 12' x 16' with a slanted 10' high roof. We need a new roof, hey, mechanic not carpenter remember. This time around our youngest son, who is a skilled carpenter will be building the new roof. Other then problems with the roof blowing off a couple of times it has worked really well and grown some amazing plants. Happy greenhouse everyone.
