15 DIY Free Greenhouse Plans for Gardeners

by Anthony

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. We started searching for greenhouse plans. I didn’t want some rinky-dink greenhouse. I wanted something that was at least 12ft wide. I wanted space to move around, store garden supplies, etc.

My Search for Greenhouse Building Plans

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 a pre-built greenhouse would be economically feasible. I searched all fall and winter.

When spring came that next year, I still had no greenhouse to start my seeds. I was disappointed in what I found for sale in the price range we could afford. The only greenhouse I could find in our price range looked nice in the photos, but the reviews indicated not one person who was satisfied with the quality. Most people stated that after a year or so, the greenhouse just fell apart.

I eventually realized that in order to get a quality greenhouse that I could afford would be to build it myself. So, that’s what I did.

I designed my own from scratch using some free drafting tools on the web. However, during my search, I came upon some great resources for greenhouse designs that can fit into any budget. I hope you enjoy the free greenhouse plans that I found.

If these plans don’t end up satisfying you, I recommend these books for more reading:

Now, on to the plans.

I used the plans on http://www.EasyGreenhouse.info and built my own greenhouse VERY cheap and easily! It was the best decision I’ve ever made. To my family and I, it just made economic sense to build a DIY greenhouse. We spent a fraction of the cost of buying an expensive pre-built one that just have to be assembled anyway…why pay inflated prices for material? The guide on that website is so very easy to follow and it doesn’t matter if you’re a total beginner like us. We were on a very small budget and found so many wonderful plans for our greenhouse…it was hard to pick just one, but the one we chose is terrific! We actually built the one that is featured on the website’s homepage. I love growing fruits and vegetables for my family all year round! There’s no such thing as out of season for us anymore! I finally have the greenhouse of my dreams and it was VERY affordable!

I am planning for retirement and the biggest part of that is building a tiny house on wheels. One of the things I would love to work into the tiny house is a small vertical greenhouse, 2 ft wide x 2 ft deep. and it would be approximately 8 ft. tall. All glass with 2 sides being outside. Or 18″ deep by 3 ft wide all glass and the 3 ft. wall would be facing the outside. I’m also trying to figure out a water barrel to water the plants. I want to be able to have some fresh vegetables and herbs no matter what time of year it is. Does any of this make sense or sound feasible?
