If you’re a gardener, who also loves DIY projects, building a shed greenhouse combo can be the perfect solution. This hybrid structure combines the storage space of a shed with the plant growing benefits of a greenhouse, giving you a versatile and functional area to organize tools while nurturing plants. Whether you’re tight on space or simply want to maximize outdoor area, a shed greenhouse combo is a practical and aesthetically pleasing addition to any backyard.
In this guide, we’ll walk you through everything you need to know about building a shed greenhouse combo, from planning and design to construction tips and materials. We’ve compiled eight steps for you to understand. By the end, you’ll have knowledge to create a structure that serves as both a tool shed and a plant sanctuary.

Step 1: Planning and Design
Before you start gathering materials or picking up tools, you’ll need a solid plan in place. A well thought out design ensures that your shed greenhouse combo meets your needs and fits seamlessly into your outdoor space.
Determine the Purpose
The first thing to consider is how you plan to use the structure. Will it primarily be a greenhouse with some storage, or more of a shed with a greenhouse section? This decision will dictate the size of each portion. If you’re serious about gardening, you’ll want the greenhouse side to be larger. If storage is your priority, you might want more shed space.
Pick the right location
Location is key for a shed greenhouse combo. Ideally, the greenhouse portion should receive plenty of sunlight throughout the day, while the shed section can be placed in a more shaded area. Orient the greenhouse section toward the south (in the Northern Hemisphere) for maximum sun exposure. Ensure the spot is level, has good drainage and is easily accessible from your home or garden.
Size and Layout:
Think about the size of your structure. A typical greenhouse combo might be 10 x 12 feet but this can vary based on your available space and needs. Plan the layout so that the shed portion provides enough room for your tools, equipment, and maybe even a workbench. The green house section should include enough space for shelving, planting beds or hanging baskets.
Choose the Materials
For the shed portion, durable materials like wood or metal are ideal. For the greenhouse part, you’ll need a material that allows sunlight to penetrate. Polycarbonate panels are a popular choice because they are lightweight, durable, and provide excellent insulation. Clear plastic sheeting or glass are other options, depending on your budget and climate.
Step 2: Collect the Material
Once you’ve finalized your design, it’s time to gather materials. Here’s a list of essential items you’ll likely need for building your shed greenhouse combo:
- Foundation Materials (Concrete blocks, pavers, or treated wood for the base)
- Framing Materials (Pressure Treated lumber or metal)
- Greenhouse covering (Polycarbonate panels, clear plastic sheeting, or glass)
- Roofing materials ( metal sheets, shingles, or translucent panels for the greenhouse side)
- Doors and Windows (for ventilation and accessibility)
- Insulation Materials (If you’re in a colder climate)
- Fasteners (Nails, screws and bolts)
- Tools (Saws, drills, measuring tape, level hammer)
It’s a good idea to buy more materials than you think you’ll need to account for mistakes or adjustments during the build

Step 3: Building the Foundation
A strong foundation is essential for any shed greenhouse combo. This ensures the structure stays level and lasts for years. There are a few foundations options to consider:
Concrete Slab:
This is the most durable and permanent option but requires more work.
Gravel and Paver Base:
A simpler and more affordable option, which provides good drainage.
Wooden Base:
Using pressure treated wood, you can build a raised platform for your shed greenhouse combo, keeping it off the ground and preventing water damage.
Lay out your foundation according to the size of your design, making sure it’s square and level.
Step 4:Framing the Shed and Greenhouse
Now it’s time to start building the frame. Begin with the floor, using pressure treated lumber for durability. The frame will consist of separate sections for the shed and greenhouse, so start by framing out the shed portion, following typical shed building techniques

Step 4: Framing the shed and greenhouse
Now it’s time to start building the frame. Begin with the floor, using pressure treated lumber for durability. The frame will consist of separate sections for the shed and greenhouse, so start by framing out shed portion, following shed building techniques
Shed framing
- Build the base with joists spaced evenly for stability
- Construct the wall frames using 2 x 4 lumber, ensuring that the shed walls are plumb
- Install the roof trusses or rafters for the shed portion, and secure them in place.
Greenhouse Farming
- For the greenhouse portion, use lighter materials like aluminum or thinner wood for framing
- Space the frames farther apart to allow for more sunlight to penetrate
- Make sure the greenhouse roof is slightly sloped to allow rainwater to run off
At this stage, it’s important to install any windows or ventilation options for both sections of the structure. Proper airflow is essential in greenhouses especially during the summer months, to prevent overheating.
Step 5: Installing the Greenhouse Cover
The greenhouse section will need a covering that allows sunlight to pass through while maintaining warmth. Polycarbonate panels are ideal because they are both durable and provide excellent insulation. However, clear plastic sheeting is a more affordable option, though to be honest, it won’t last as long.
Attach the Panels
Carefully attach the polycarbonate panels to the greenhouse frame. Make sure to secure them tightly to avoid gaps that could let in cold air or allow water to seep through. Overlap the panels slightly to ensure good insulation and a watertight seal.
Roof Installation
For the roof, you can either use the same transparent panels or opt for a sturdier material like corrugated plastic or even polycarbonate. Make sure it’s securely attached and has adequate slope for drainage.
Step 6: Roofing the Shed Portion
For this shed portion, you’ll want a solid weatherproof roof. Metal roofing sheets or asphalt shingles are common choices. Install the roof as you would on any regular shed, ensuring there are no leaks and that it’s securely attached to the framing.
Step 7: Interior Setup
With the exterior completed, it’s time to set up the interior. Organize the shed portion by installing shelving, hooks, or pegboard to keep tools neatly arranged. Add a workbench if you have space and use bins or containers to store smaller items. In the greenhouse portion, add plant benches, tables or hanging baskets depending on what plants you’ll be growing. Make sure the layout allows for good light penetration and air circulation.
Step 8: Ventilation and Temperature Control
Both the shed and greenhouse portions need proper ventilation. Install vents in the greenhouse to allow hot air to escape during warmer months. For the shed, windows or small vents will keep space from becoming too musty. If you live in a colder climate, consider installing a small heater of insulation in the greenhouse portion to maintain a consistent temperature for your plants.
