Can You Attach a Greenhouse to a Shed?

Yes, it is possible to attach a greenhouse to a shed, but it depends on various factors, such as the design of the shed, the size of the greenhouse, and the type of attachment you want to use.

If the shed has a sturdy frame, you may be able to attach a greenhouse kit directly to it using bolts or screws. You will need to ensure that the shed’s roof is strong enough to support the weight of the greenhouse and that the attachment points are secure.

Another option is to build a custom greenhouse that is designed to attach to the shed. This may involve designing a custom frame or using a modular greenhouse system that can be configured to fit the dimensions of the shed.

It’s essential to ensure that the greenhouse is properly sealed to prevent heat loss and moisture buildup, which can cause damage to both the shed and the greenhouse.

Overall, attaching a greenhouse to a shed can be a great way to expand your growing space while also making use of existing structures on your property. However, it’s important to consider the structural integrity and compatibility of the two structures before starting the project.

What are the Advantages & Disadvantages of a Attached Greenhouse?

An attached greenhouse is a greenhouse structure that is built as an extension of an existing building, such as a house or a garage. Here are some advantages and disadvantages of an attached greenhouse:


Easy Access… One of the main advantages of an attached greenhouse is that it provides easy access to the greenhouse from the main building, making it easy to tend to plants and maintain a comfortable environment for them.

Space-Saving… An attached greenhouse can be a great option for those who don’t have a lot of outdoor space. By building a greenhouse as an extension of an existing building, you can save space and still have room to grow plants.

Energy-Efficient… Can be more energy-efficient than a stand-alone greenhouse because it can utilize the heating and cooling systems of the main building. This can lead to lower energy costs and a more stable environment for plants.

Aesthetically Pleasing… Can be designed to complement the existing architecture of the main building, creating a visually appealing addition to the property.


Limited Sunlight… Depending on the orientation of the main building, an attached greenhouse may receive limited sunlight, which can limit the types of plants that can be grown.

Space Limitations… While an attached greenhouse can be space-saving, it also means that there may be limitations on the size and layout of the greenhouse. This can limit the types of plants that can be grown and the overall yield.

Risk of Pests and Diseases… It also can be more prone to pests and diseases because it is attached to a building that may already have pests and diseases. Careful attention to sanitation and pest management is important to prevent the spread of pests and diseases to the greenhouse.

Temperature Control… While an attached greenhouse can be energy-efficient, it can also be more difficult to control the temperature of the greenhouse because it is connected to the main building. This can be particularly challenging if the greenhouse needs to be kept at a different temperature than the main building.

Overall, an attached greenhouse can be a great option for those who want to grow plants in a limited space, and who have the right conditions for it. However, careful consideration of the advantages and disadvantages is important before deciding whether an attached greenhouse is the right choice for your needs.

How To Transform Your Storage Shed into A Garden Greenhouse

Transforming a storage shed into a garden greenhouse can be a fun and rewarding DIY project.

Here are some steps you can follow to make the transformation:

Evaluate your Shed… The first step is to evaluate your storage shed to determine if it’s suitable for conversion into a greenhouse. Look for any leaks, cracks, or other structural issues that need to be addressed before you begin the conversion process. You should also consider the size and location of the shed. Ideally, it should have plenty of natural light and be situated in an area that receives ample sunshine throughout the day.

Install Windows… Since your greenhouse needs to let in natural light, you will need to install windows. Depending on the size of your shed, you may need to install several windows to ensure adequate light. Consider using insulated glass to keep the temperature inside the greenhouse regulated.

Ventilation… Proper ventilation is crucial for any greenhouse. Install vents at the top and bottom of the greenhouse to promote air circulation. You can also install fans to improve ventilation during the summer months.

Install Shelving… To maximize your space, consider installing shelving along the walls of your greenhouse. You can use these shelves to store potted plants, gardening tools, and other supplies.

Insulate the Walls… Insulating the walls will help to regulate the temperature inside the greenhouse. Consider using foam insulation panels or bubble wrap to insulate the walls.

Flooring… Depending on the flooring in your shed, you may need to install a new one. You can use materials like gravel, sand, or concrete to create a level surface for your plants.

Add Electricity… If you plan to use your greenhouse year-round, you may need to add electricity. Consider installing outlets and lighting fixtures to make it easier to work inside the greenhouse. You can also add a skylight to get some natural light, check out my article How to Install a Skylight in a Shed for more information.

Add Water Supply… Plants require water to grow, so you will need to provide a water supply to your greenhouse. You can install a rain barrel or a hose to provide water.

What are the Three Basic Types of Attached Greenhouses?

The three basic types of attached greenhouses are:

Lean-to Greenhouse… This type of greenhouse is built against an existing structure, such as a house or garage, and shares one of its walls. A lean-to greenhouse is typically less expensive to build and can save on heating costs by sharing heat with the adjacent structure. Check out my article How to Choose a Lean-to Greenhouse Kit for tips on building a lean to greenhouse.

Even-Span Greenhouse… This type is a standalone structure that is attached to another building with a matching roof slope. An even-span greenhouse has a ridgeline that is parallel to the adjacent structure and offers a wide range of sizes and configurations.

Uneven-Span Greenhouse… This type of greenhouse is similar to an even-span greenhouse, but the roof slope and height differ from the adjacent structure. An uneven-span greenhouse is a good option when the slope or orientation of the adjacent structure does not match the desired greenhouse orientation.

Can you Turn a Barn into a Greenhouse?

Yes, it is possible to turn a barn into a greenhouse.

The conversion process would involve several steps, including:

Clearing out the Barn… The first step would be to remove any equipment, hay, or other materials that may be in the barn.

Insulating the Walls… Barns are typically not well-insulated, so adding insulation to the walls and ceiling would be necessary to maintain a consistent temperature inside the greenhouse.

Installing Ventilation… A greenhouse requires proper ventilation to maintain air flow and prevent the buildup of moisture. This could be achieved by installing vents or fans in the roof or walls of the barn. Check out my article Should I Install a Roof Vent for Shed Ventilation? For more information.

Adding Lighting… Greenhouses require ample amounts of natural light to promote plant growth, so the barn may need additional lighting installed.

Installing a Heating System… Depending on the climate, a heating system may be required to keep the greenhouse warm during colder months.

Choosing a Growing Medium… Greenhouses typically use a soilless growing medium, such as peat moss or coconut coir, to promote plant growth.

Can a Greenhouse be Built on a Slope?

Yes, a greenhouse can be built on a slope, but it will require some additional planning and design considerations.

Here are some factors to keep in mind when building a greenhouse on a slope:

Site Preparation… The site for the greenhouse will need to be leveled to ensure that the structure is stable and that the plants are growing on a level surface. This may require some grading or excavation work to create a level foundation.

Drainage… It is important to ensure that there is proper drainage on the site to prevent water from pooling around the greenhouse. This can be achieved by grading the site or installing a drainage system.

Orientation… The orientation of the greenhouse should be carefully considered on a slope to ensure that it receives adequate sunlight and is protected from wind and other weather conditions.

Anchoring… Due to the slope, the greenhouse may be more susceptible to wind and other weather conditions. Therefore, it is important to anchor the structure securely to prevent it from shifting or being damaged. Get more information on anchoring options in my article The Ultimate Guide to Choosing a Shed Anchor Kit.

Access… Consideration should be given to how people will access the greenhouse on a slope. This may require the installation of stairs or a ramp, which can add to the cost of construction.
