This greenhouse is a relatively simple design. So it’s a great project to get started with. Framed completely from 2×4’s this sturdy greenhouse is completely customizable to fit your needs. The design can easily be changed to increase or decrease the greenhouse’s size.
If you do decide to build this greenhouse I would recommend laying concrete underneath the walls. Then bolt the walls to the concrete. The weight will keep the weather from knocking your greenhouse down. The builder says that that the greenhouse has withstood 60 mph wind, but i would feel better if it had more weight to it. The greenhouse cost about $150 in framing materials and $450 in corrugated panels.
