From a business point of view, a greenhouse can be very profitable, as you can grow spring vegetables all year long. This is true even in the winter months when you have to normally depend on exports. Commercial greenhouses are much bigger than the standard greenhouse, sometimes extending to several hundred feet. Like the standard greenhouse, they can be designed to fit any building and zoning codes.

The first and most important step in commercial greenhouse construction is to pick the right location. Although you can build a standard greenhouse almost anywhere, a commercial greenhouse has many things that need to be taken into consideration. From a legal point of view, you will need to check on the zoning rules (greenhouses can be built only in certain zones), building codes and environmental feasibility. From a monetary point of view and for higher profits, you will have to check land rates, highway accessibility, and availability of water and the heat and electricity tariffs of the region.

A freestanding greenhouse is best suited for a total structure area of under 10,000 sq. feet. It is also good for regions that receive heavy snowfall and for land with an uneven surface. A gutter-connected greenhouse is best suited for an area between 10,000 and 20,000 sq feet. This structure will greatly reduce your heating bills, as the heat can be centralized. Your local greenhouse manufacturer will supply you with all that is needed.

For a commercial greenhouse, you will need a good climate control system to heat or cool the greenhouse depending on the season. You will need to lay a gravel, concrete or plastic flooring to prevent insect and diseases from affecting your plants. You also need to put benches inside, so that your plants will receive even air circulation and drainage.
