The average cost of building a greenhouse is $13,000 - $20,000.
A greenhouse is a structure that is designed to help plants grow year-round. It affords protection from the elements while allowing sunlight to flow through its confines. Greenhouses are always constructed of a transparent material such as glass or plastic. These include polyethylene 1, corrugated fiberglass 2, PMMA acrylic glass, and polycarbonate 3 sheets. Structures range in size from small garden sheds to large, industrial greenhouses.
Building a greenhouse costs on average $13,000 to $20,000, with the average homeowner spending around $16,500 on building a greenhouse measuring 12'x12' that is constructed from polycarbonate sheets and a cedar wood frame.

The costs for the project will include:
Excavation and site preparation - costs will vary according to the level 2 of work necessary, but all such projects would require the leveling of the site in order to receive the concrete and the drilling of a well with a 6" diameter feed and a horse power pumping 1 mechanism (unless the pre-existing well or water supply could be easily tapped into and channeled to the greenhouse. This might be problematic in areas of heavy frost, however);
Concrete - the knee walls and flooring of the greenhouse would demand roughly 3.5 cubic yards of concrete. This is priced at an average of $75 per cubic yard, and with labor would cost around $540;
Materials - the greenhouse described here would demand a heavy steel frame, 8' walls constructed of multi-wall polycarbonate or glass, roofing vents, and electronic exhaust fans. The average pricing on a 144 square foot greenhouse using such materials is $2700;
Heating - greenhouses located within areas that receive freezing weather might require the addition of a heating unit. These come as electric and propane models, and the average price for a unit sized to meet the needs of the structure described here would be less than $250;
