How to Build an Affordable Greenhouse?
Apparently, it requires a lot of money and time to build a greenhouse. A small commercial-made greenhouse may cost around $1000 to $5000. However, if you cannot afford to spend that much money, there are several ways to build a low-cost greenhouse. You need just a bit of creativity and a few skills to create one.
Here are some ways to cut your greenhouse construction cost:
- Use affordable materials
Some of the most common low-cost greenhouse construction materials used by gardeners are plastic sheets, PVC pipes, saplings, hog panel fence mesh, and lumbers. You don’t have to purchase expensive materials to build your own greenhouse. You just have to do some research on where you can buy inexpensive materials around your area.
2. Repurpose some materials
A greenhouse usually has lots of windows. If you have old windows or sliding glass doors in your house, you can use them to build a low-cost greenhouse. You may also buy several items, such as heaters, fans, and shelves, in second-hand stores and online. This can help you a lot in cutting costs for your greenhouse.
3. Use a wall from an existing structure
Another way to build a low-cost greenhouse is to borrow a wall from an existing structure like your house, garage, or shed and attach your greenhouse. This way, you can build a lean-to greenhouse, which is more affordable compared to a freestanding structure.
However, building a connecting greenhouse to an existing structure will require professional help to ensure it is done right and can last long. Therefore, you will have to pay an architect or builder to help you achieve this plan.
4. Build a small one
A larger greenhouse requires more money as you need more materials, space, maintenance, and labor. However, keeping your greenhouse small means you don’t have to spend much on its construction and maintenance.

If there are any gaps on your walls, windows, and door, fill them in. Make sure there are no extra holes in your wall, windows, and door. Also, your greenhouse should be appropriately insulated to protect your plant during winter and keep the temperature warm inside.
6. Install the roof
This part can be challenging for someone who is not a professional or lacks construction skills. First, you must ensure the roof is securely attached to the structure. Also, ensure no holes on the roof to avoid leakage during rainy or snowy seasons.
7. Install Shelves
After setting up your greenhouse’s structure, it is time to install the shelves where you will be placing your plants. You may use second-hand shelves or build some using scrap wood.
