It will talk about the different types of greenhouses, the materials you need, and how to put them all together. So if you are interested in building one in your backyard, keep reading!

The Different Types Of Greenhouses

If you’re interested in gardening, you may have considered building a greenhouse. Greenhouses provide a controlled environment that can extend the growing season and protect plants from harsh weather conditions. But with so many different types of greenhouses on the market, choosing the one that’s right for you can be challenging. So here’s a quick overview of the most common types of greenhouses:


An A-frame greenhouse is a type of structure typically used for gardening and horticulture. The name comes from the greenhouse’s triangular shape, with two sloped sides and a flat top. A-frame greenhouses are very popular because they are relatively inexpensive to build and can easily adapt to different climates and weather conditions. Most A-frame greenhouses consist of metal or wood and have a translucent covering that helps to trap heat and light. This covering creates a warm, humid environment ideal for growing plants.

Hoop House

A hoop house is a type of greenhouse typically made from metal or PVC pipe. The pipes are bent into an arch shape and then covered with greenhouse film. Hoop houses offer many advantages over traditional greenhouses. They are cheaper to build, and you can assemble them relatively quickly. In addition, they can be easily taken apart and moved to a new location if necessary. Hoop houses also provide better ventilation than traditional greenhouses, which is important in hot climates. However, they can be more susceptible to damage from high winds.


A lean-to greenhouse is a type of greenhouse that attaches to the side of a building. The slanted roof allows maximum sun exposure, ideal for plants that need a lot of sunlight. Lean-to greenhouses are a great way to start gardening, as they are relatively easy to build and maintain. In addition, they can be relatively cost-effective, as they make use of existing structures. However, lean-to greenhouses do have some drawbacks. For example, they can be prone to leaking and overheating and may not provide enough space for large plants.

Materials You Need To Build A Greenhouse

Regardless of which style of greenhouse you choose, there are certain materials that you will need to build it. For starters, you will need a foundation. You can make the foundation out of concrete, wood, or metal. The foundation will provide support for the walls and roof of the greenhouse. 

In addition, you will need to choose a material for the walls and roof. Glass is the most popular choice, as it is transparent and allows maximum sunlight to enter the greenhouse. However, it is also the most expensive option. 

Polycarbonate is a cheaper alternative made out of plastic. It is not as transparent as glass, but it still allows sunlight to enter the greenhouse. Finally, you will need a way to ventilate the greenhouse. You can do this with windows, vents, or fans. Ventilation is important to regulate the temperature and humidity inside the greenhouse.

Steps To Build A Greenhouse

Once you have all your materials together, you’re ready to start building your greenhouse! The following steps will give you a basic guide to setting up your new structure.

Step 1: Choose A Level Spot

When choosing a location for your greenhouse, you must pick a level spot. Placing your greenhouse on an uneven surface will cause problems down the road. Water will not drain properly, one side of the greenhouse will be higher or lower than the other, and it just looks terrible overall. When you have decided on the perfect level spot for your greenhouse, mark out the area that it will cover. That way, you will have a guide when it comes to digging the foundation.

Step Two: Prepare The Foundation

The next step is to prepare the foundation for your greenhouse. If you are using a concrete foundation, you must pour the concrete and allow it to cure for at least 24 hours. If you use a wood foundation, clear away debris from the area and level out the ground. You can do this by using a shovel or a rake. You may also need to add or remove soil to get the area leveled.

Step Three: Build The Walls

After you have prepared the foundation, you can start building your greenhouse’s walls. If you are using glass panels, you will need to assemble them according to the instructions that come with them. Once the panels are in place, you will need to put up the framing. Again, you can do this with wood or metal. Make sure the frame is level and square before proceeding to the next step. It is also a good idea to put in some cross-bracing at this point to increase the stability of the walls.

Step Four: Install The Roof

The roof of a greenhouse is vital as it protects the plants from the elements. For this reason, it is crucial to ensure you install it correctly. The first step is to put up the framing for the roof. You can use wood or metal, but make sure it is level and square. Once the frame is in place, you can cover it with glass, polycarbonate, or plastic. Just be sure to use a material that will allow sunlight to enter the greenhouse.

Step Five: Ventilate The Greenhouse

As mentioned before, it is essential to ventilate the greenhouse to regulate the temperature and humidity inside. You can do this by installing windows, vents, or fans. Make sure to place them strategically to get the best results. For example, if you use windows, you need to open them on hot days to let the heat out. Likewise, you will need to close them on cold days to keep the heat in.

You’re Ready To Build A Greenhouse!

Building a greenhouse is a great way to get into gardening. It allows you to grow plants that would not usually be able to survive in your area and extend the growing season. And with some planning and effort, anyone can build a greenhouse! Just follow the steps outlined in this article, and you’ll be on your way to becoming a green thumb in no time. Just make sure you do a bit more research into the specific type of greenhouse you want to build.
