Do-it-Yourself Greenhouse Plans

Talk to people you know who have greenhouses and peruse additional information online, in books and in gardening publications to learn about the many options available. Each one has advantages and drawbacks, depending on your goals, financial considerations and space and other land features.

Some examples include free-standing greenhouses versus lean-to varieties in addition to various frame shapes such as gothic, rigid frame and A-frame buildings. Coverings may be plastic, glass or fiberglass. (Ref 2)

Purchase a greenhouse kit or plans, or develop your own plans. People who decide to create their own plans must ensure that all necessary elements of the greenhouse and its environment are included. This means the plan needs to include the frame, exterior and foundation. Consider environmental controls, including heaters, insulation, vents, fans, coolers and watering systems as well. (Ref 1)

Construct your greenhouse from local, unique materials to lower cost and create a one-of-a-kind structure, as demonstrated in, "How to Build a Greenhouse from Used Windows or Storm Doors" by Nevin Hawlman. (Ref 3) You can also check garage sales, auctions, estate sales and the classifieds for free and cheaper materials.

Plan the space carefully before purchasing the greenhouse plans or creating your own. An 8-foot by twelve-foot greenhouse may sound like just the right size, but you have no way of knowing if it's too large or too small without taking the time to calculate and measure what you want to grow in the greenhouse and the space they will require. Invest the time needed to get this part of your planning correct to avoid frustration and wasted effort later.

Find a suitable location for your greenhouse. All-day sunlight on a south or southeast side of a building works best, according to West Virginia University. (Ref 2) Remember that the sun is lower in the sky during the winter months and may be blocked by shade not present during warmer times of the year. The location must also provide good drainage and access to electrical outlets needed for environmental controls. (Ref 2)

Take in to account financial considerations when choosing or creating do-it-yourself greenhouse plans. Ever-span greenhouses that attach to another building on one side or free-standing structures provide the best investment per square foot, according to West Virginia University. (Ref 2) Overall costs may be lower with other types of greenhouses requiring less total materials, such as lean-to or window-mounted versions. Lower costs often reflect less total square footage, an important trade-off to keep in mind. (Ref 2)
