How to Build a PVC Greenhouse

This greenhouse will help you harvest the best vegetables and fruits in town!

We understand that health takes a big spin and it's important to control every detail of the food you eat. So are you asking yourself how to build a greenhouse? Easy, here is the step-by-step guide that will show you how to build your DIY Greenhouse. It takes some time to measure and cut all the PVC tubes, but you'll love the results!. This greenhouse is divided into 3 sections. So you should start doing some research about the benefits of putting certain plants together.

This PVC greenhouse is 78" wide, 130” long and 85" high, but you can adjust this greenhouse according to the space you have by editing the free 3D design. We also recommend giving it a perfect finish by sanding each PVC tube and then using a primer and finally a quick dry paint for your favorite color.

Ideal for: gardens and farms. 

Let's start with this new PVC project! Follow the steps on how to make a Greenhouse with PVC pipes.


Instructions

A note before starting - 

Please understand - the below diagrams are genuinely and carefully designed to help you navigate the build process. However, we don’t include specific recommendations for which tools, hardware, or products to use. These truly are “DIY” designs. 

As such – a significant portion of the build-process will be up to you, the builder. So please know, there is no “right” or “wrong” way to assemble any of our designs! If you need to depart from the instructions, or rearrange things along the way, feel free to. 

The only thing we ask: please be safe and use glasses and gloves while building. And of course, there’s no shame in asking an expert for help or seeking guidance from your local professionals at any time.

DIY Greenhouse with PVC Pipes Assembly Steps

How do you know which part is which from the parts list? Click on "Edit Design in 3D" button above and you'll be able to click on each part to see its name.

Step 1: Building the Base of the Greenhouse

All homemade greenhouses start by building the base. This way you can already place it where it should stay at the end of the day. The first step is to clean all your PVC pipes, then measure each piece according to your part list and then carefully cut them. 

Once you have all the parts ready make sure to sand them in case they are dirty, and if they aren't, we still recommend doing this since it helps the paint to avoid getting easily scratched. 

For this section you'll need two PVC pipes 78.7” long and six 40” long PVC pipes. Plus four 3-Way outlets slips and four Tees slips.

You'll grab your 3-way outlet and place the 78.7" long PVC pipe, then another 3-way outlet slip, then a 40" long PVC pipe followed by a 4-way outlet slip, then another 40" long PVC pipe, then another 4-way outlet slip, and then another 40" long PVC pipe. This last pipe will connect to the 3-Way outlet that will be one of the corners of your greenhouse. We'll now connect a 78.7" PVC pipe to a 3-Way outlet. This will be the next corner of your greenhouse. Now let’s connect the  three following 40” long pvc tubes, connected by Tee slips.  Doing this you should have a rectangle. One of the holes in the Tee slips and 3-way must be facing up.


Step 2: Let's put Together the Walls of your Greenhouse

For this step, bring the following parts close to what you'll be needing: eight 78" long PVC tubes and eight 45º elbows.

This section is a lot easier since you'll do the same on each 3-way and 4-way outlet. Place a 78" long PVC tube on top of the 1 1/4 " 45º elbow and each tube. The 45º elbows on the left should be facing the ones on the right, and this is it for this step. We're almost done!

Step 3:  Let’s Build the Top Section of your Greenhouse

You can glue all the parts together with PVC Cement, but we suggest you first build everything together to make sure all of the pieces connect appropriately. The cement dries very quickly, making it difficult to remove.

We will connect all the pipes together with two 18.79” long PVC tubes connected with a tee slip or cross slip if they are in the middle. Please look at the image to double check your greenhouse looks the same. In the middle for extra support, you will connect three PVC tubes measuring 40” long through the tee slips and cross slips. 

It's almost done!!

Step 4:  Finishing the Top Section of your Greenhouse

The last part we left on our PVC tubes was the 45º elbow. Now add a 27.8” long PVC pipe to each 45º elbow, followed by another 45º Elbow. The tubes on the left should be facing the ones on the right. Next, you'll do exactly the same thing, connect a PVC pipe to the 45º elbow and then add another one. 

Then just place on top the roof you did before and now you're done!
