Note: The greenhouse plans that show plastic coverings require at least 2 people and it is better if there are 4 in order to lay the plastic over the frame work.
Always read the greenhouse plans carefully and make sure that there is enough information provided for you to be able to complete the project - before you invest in materials. Some of the plans are excellent, giving a great deal of instruction in text, pictures and drawings while other plans are only drawings and still others are only sketches.
As well, some of the greenhouse plans require a woodworking shop that is outfitted with a good selection of stationary power tools such as a table saw, jointer and thickness planer.
These greenhouse plans require novice to expert woodworking and handyman skills, depending on the free plan chosen.
