Home gardening and landscaping are enjoyable hobbies for many people. If you are among them, you might benefit from a small backyard greenhouse. A greenhouse can be built easily and inexpensively in several hours using simple hand tools and materials available at most building supply stores. This publication presents plans and instructions for an easily constructed greenhouse that costs about $100 and may be used for many purposes. Measuring 12 feet by 14 feet (168 square feet), it is small enough to be unobtrusive but large enough to meets the needs of the serious grower. The completed structure is shown in Figure 1.
