For the novice, learning how to build a greenhouse can be a daunting task – so is writing about it. This article does not tell you how to actually build a specific type of greenhouse as each type of greenhouse requires different construction materials, building technique, et.  However, this article will introduce you to the basics on how to build a green house like planning, budget, location, the types of greenhouses available and some common building materials.

Prerequisites - Things to Consider Before Building a Greenhouse
The type of green house you build will depend heavily on several factors like your start-up budget, the architecture of your home, available space, the amount of space needed, and environmental controls to monitor humidity and control temperature. All these elements should be considered before you delve into building a green house.

Your Greenhouse Budget
It’s difficult to say which of the prerequisites are the most important, however, it’s safe to say that your budget is a primary determining factor in the type and size green house you can build or afford. Tally up your available cash and proceed to the next paragraph.

Available Space for Greenhouse
The amount of space you have is also a primary determining factor in the type and size green house you can build. If you have an unlimited budget and can afford a large, commercial greenhouse, but don’t have the space to house it, then your budget is irrelevant.

Before going into your yard to measure a space for your green house, it’s equally important to choose a good spot. Let’s proceed to the next paragraph to learn about selecting the perfect location for your green house.

Finding the Perfect Location for your Greenhouse
There are many tricks professional gardeners use to maximize the performance of their greenhouse production. Finding the right location is just one of the many things the pros consider when building a green house.

Plant’s will benefit most and are more productive when they bask in morning sunlight. This technique is used to give the plants an early start by allowing the plant’s food production process to begin early leading to vigorous growth and development.

The south or southeast side of your home or shade tress are prime locations. On a seasonal note, the eastside will receive the most sunlight during November to February. However, if you can’t build on the south or southeast side, the next best choice is the southwest and westside where the plants will receive the afternoon-evening sunlight. Locations to the north are the least desirable unless you plan on growing plants that require little sunlight.

During hot summer months, deciduous trees like oak, can "used" as shade for your green house during the intense afternoon heat. Precise planning is required when utilizing techniques such as this because you do not want the trees to block morning sunlight.

During winter months, deciduous trees will shed their leaves and allow sunlight to reach the greenhouse. Avoid building your greenhouse near evergreens because they retain their foliage all year long and may block sunlight during winter months when the sun is less intense.

An ideal location may vary according to your geographical location. Please research your area to maximize morning and/or afternoon sunlight.

Finding the Perfect Location for your Greenhouse - Additional Considerations
It may be a good idea to build your greenhouse above ground to allow rain and irrigation water to drain. The location should also be accessible to sources of irrigation supply, heat, shelter from cold wind and close to a heat source.

For example, if you use computers and electronic devices to monitor the greenhouse temperature, you will need access to a power outlet or source. It’s a good idea to remain close and accessible to all external requirements.

Once you’ve determined where to put your green house to maximize plant growth and the greenhouses’ overall performance, then it’s time to take the measurement of the available space to determine the size of the greenhouse you can fit.
