I was always fascinated by the idea of building my own greenhouse and recently when I moved into a house which had a fairly big backyard, I decided to make a greenhouse which would be large enough but at the same time should not be too costly. My wife and son got involved into building this and very soon it turned into a joyous in-house project. The size of our greenhouse was 20 feet by 16 feet and we used aluminum sheets for the frame and the walls. The roof was made strong by installing fiber glass paneling. Though all these were done spontaneously but later on I realized that one should have Greenhouse Plans before commencing work on such a project. We also installed an aluminum sheet door to keep pests away.
