Adding a Greenhouse to Your House? Some Things to Consider

When a homeowner is interested in extending their growing season, they may consider the addition of a greenhouse. A greenhouse provides an array of benefits that many people do not realize right away. However, before making this investment, it is necessary to consider a few things. Keep reading to find out what these things are.

Attached or Freestanding

Regardless of if someone is growing vegetables or if they go to Weed Seeds USA to purchase cannabis seeds, ensuring the right type of greenhouse is selected is essential. Freestanding greenhouses offer the perfect opportunity to create an all-new space with very few restrictions.

However, the costs related to this construction are higher than with an attached structure. This is an important consideration that each homeowner needs to factor into their decision. Budget constraints are also important factors.

Greenhouse Orientation

In North America, the proper orientation for greenhouses is typically south or southeast. This is because, in colder climates, it is essential to capture the morning sun. Sometimes, an east-facing orientation will also work. Keep in mind, though, that these are just recommendations. Each person needs to consider how their greenhouse will receive the most sun to determine the proper orientation.

The Foundation

There are several methods and materials for creating the foundation of a greenhouse. These can be used for building any structure, including a greenhouse. Some common options include concrete piers that are tied together with the structureโ€™s frame. Other options include sunken pressure-treated posts used as foundation footers.

The Roof Slope

If the area is subjected to a lot of snow, choosing a 6/12 slope is necessary to shed heavier loads of snow. Since the greenhouse will be warmer than the outside air, the layer of snowmelt may form between the polycarbonate glazing and the snow, which helps the roof eliminate any excess weight. Snow tends to stick to the double-inflated poly.

Glazing and Framing Materials

The most common framing materials that are used for greenhouses include metal and wood. Wood is ideal for smaller greenhouses and is more affordable. A cheaper option is rough-sawn, beetle-kill, or salvaged lumber. Remember, if the wood is used, it will require more upkeep than metal but, in a drier climate, it can last 50 years or more with proper maintenance and care.

Almost all commercial greenhouses available today are designed using galvanized steel for the frame. It is possible to purchase kits that use wood or metal to create these buildings, which also simplifies the building process.


Insulation must be installed on the west and north walls of the greenhouse. Be sure to insulate the walls properly if they do not have glazing. Structural insulated panels or foam insulation will work well, but they must be sealed and remain dry. This material is not rated for the high levels of humidity found in a greenhouse.
