Of all the large greenhouse plans available on the internet, it generally comes down to 2 designs: The Victorian-style greenhouse, and the Arch/Hoop design. Both are built completely different, and both provide plenty of space. This article compares the 2, and helps you choose what’s best for you.
The Victorian-style Greenhouse
This is the most traditional looking of the designs. It’s tall, has a beautiful angular roof, and looks very professional. Another benefit is that it’s nowhere near is difficult to construct as it seems. In fact, with some good quality greenhouse plans you can have it up in only 1 weekend.
This type of greenhouse requires quite a bit of lumber for the framing. Treated pine or cedar will suffice. As far as solar material goes, glass, polyethylene plastic, and cloth have all been used with good results. It mainly comes down to a matter of aesthetic taste.
The Arch/Hoop Greenhouse
This is a lot cheaper of the 2. The base is made from timber. Again, treated pine or cedar work well. Keep in mind that cedar contains a natural enzyme that protects it was wood rot, whereas pine needs to be chemically altered.
For the large “hoops” that make up the majority of this greenhouse, you can’t go wrong with old fashioned PVC piping. This is what makes building this greenhouse so cheap. You will easily be able to throw this one up in less than a day, especially if you have some experience with a hammer.
Obtaining Construction Plans
The first place to look for large greenhouse plans is your local library. They should have a “DIY” or “construction” section. Alternatively, check out local bookstores and hardware stores. You can also download plans in PDF format from the internet. These schematics packages generally provide you with more than one plan.
