15 Free Greenhouse Plans DIY

Several years ago while my wife and I were looking for our little homestead, the one thing I was most excited about was building a greenhouse for my plants. I didn’t want some rinky dink greenhouse; I’m talking about something that was about 12ft x 12ft. As a typical guy, I subscribe to the belief that bigger is better no matter if we needed it or not.


We closed on our home in August of that year so I spent that fall comparing options, prices, and styles. I shopped some of the larger retailers to see if purchasing an already built greenhouse would be economically feasible for us. I literally searched all fall and winter, when spring came that next year, I was still “greenhouse-less”. I was so disappointed in what I found for sale in the price range we could afford. I didn’t really want to spend more than $500 since we were already on a tight budget. The only greenhouse that I could find in that price range was very attractive from the photos but then I read the reviews that were posted on the website by people who purchased this item in the past. There was not one person who was satisfied with the quality of the greenhouse, most people stated that after a year or so, the greenhouse just fell apart. I quickly realized in order to find a greenhouse that would last me several years was either going to cost me several thousands of dollars or I would have to build it myself. Needless to say, building my own was the way that I went.

I eventually designed my own from scratch using some free drafting tools on the web. During my search for plans, I came upon some great resources for greenhouse designs that can fit into any budget. As far as my greenhouse, I will be doing a series of articles and videos on that soon, in the meantime, I hope you enjoy the free greenhouse plans that I found
