Casa Verde is the result of a school assignment. We worked on this project with 4 students Industrial Design from the University Ghent/ Howest Kortrijk (Belgium).
We were working on different 'Urban Gardening' projects and our assignment was to make a modular greenhouse.
Although we ourselves are not gardeners, we worked in cooperation with an Urban Gardening project, providing us with vital information for the success of our product and we believe that this project could prove useful for a lot of people.

It being a school project realized in a two week span, it means this is a concept that has not been tested, so as of yet we can not guarantee this will work. It would therefore be very appreciated if someone out there would want to test this and let us all know how it worked out.

For now, let's be positive and assume this greenhouse will in fact work. We believe it would.

Casa Verde is unique in ways that it

- is very modular: One module can be used to make all kinds of shapes depending on the surface and height you need to cover.

- gives a visual added value to your garden: Unlike a lot of other DIY greenhouses, this greenhouse looks really good and you definitely will not want to hide it in the back of your garden.

- is durable: It is made out of firm plastic that holds its shape and is weather resistant.

- is stowable: The whole construction can easily be folded to take in very little space once stored in the winter months.

- is affordable: It is not the cheapest greenhouse possible to make, but seen its durability and innovation, it is very good value. For about €50 we covered almost 1,2 m².

And the best of all, you can easily make this. You don't need to be an engineer to be able to make this and almost everybody has the needed tools at home.


Step 1: Materials and dimensions

We constructed our greenhouse with triangles of 56x56 cm. We chose these dimensions because our client asked for a greenhouse fitting in a 1,20 m grid and because it is a good working standard. We suggest to use these measurements because it provides plenty of space to work on the plants and this makes for a good grid to plant herbs and vegetables at regular distances. These measurements come from a well know method called 'square foot gardening'.

Of course, you are free to tweak this greenhouse to your own liking and change the measurements to fit the plants you want to grow. Maybe you could even change the material and scale everything up to make this into a children playhouse.

The material list is for a greenhouse with 56 x 56 cm triangles, but the graphic above and the letters between brackets will help you to rescale the dimensions. However, you don't need to follow these dimensions very strictly, it is more like a guideline.


- cutter
- hole punch
- handdrill
- ruler
- protractor
- pencil


- sheets of 2.5mm Polystyrene (or another transparant, outdoor purpose plastic like PVC, HDPE, PMMA)
To make 12 triangles with sides of 56cm (A) you need a sheet of 1m x 2m.

- 1mm PVC sheet (or another flexible, outdoor purpose plastic)
You need 6 rectangles of 12,5cm (B) x 8cm (c) per triangle.

- 24 cm cable ties (6 per triangle)
If you don't like the look of cable ties, you can also opt for rivets.

- 58 cm (A+2cm) wooden poles (about 2 per triangle)
Some longer poles can be useful to pin in the ground.

to cover 0.36m² you need 4 triangles
0.72m² you need 8 triangles
1.42m² you need 16 triangles

<p>Very interesting, as soon as i have time i shall try do it</p>
<p>Very nice, I love the versatility.</p>
<p>That is SOOOO Kewl! I guess a guy could also use like 2ltr bottles and cut out the pieces to hold the dowels right? Or would that be to thin? I can't w8 to try this!</p>
<p>Dude you can gain money from this idea! you can go to Quirky.com and post this idea in there if many people voted for it. the company will manufacture it and give you some money prepetually! they call it prepetual royalty. if you do want to give it a try search the internet for &quot;quirky.com cupon codes&quot;. before you can post your idea on the site. you need to pay 10$ first but with cupon codes you no longer have to. if your not interested. can i have your permission to post this? ok?</p>
<p>Thanks for the compliment. This was a school project and we are not interested in making this a commercial product. However, we wouldn't appreciate it if you would use our product for your own commercial benefit. According to the licence of this instructable, you aren't even allowed to. I hope you understand.</p>
<p>Voted! This is brilliant. We would call these cloches rather than greenhouses but not important. Is there any reason you could not skip the rectangles and just use cable/zip ties to form a loop through each hole? Then they would act as the hinge too. I hope my sketch will help explain. </p>
<p>We made the rectangle loops so that everything fits well together and you don't get (too much) open spaces where wind and rain can come trough. The poles close some of the space, but not all, so therefore the rectangles.</p><p>Good question though and thanks for the vote ;)</p>
Looks good but where's the video?
There is a video on the setup and disassembly in step 7, but we didn't make a video of every seperate step because we thought it was already clear as it is.
Simpel en geniaal!!
Nice design.
<p>I will have to try this. I live in North Idaho were the growing season is very short so this seems like an excellent cost effective solution to jump start the growing season.</p>
<p>Impressive start, this is totally awesome!!!</p>
<p>Enne, 'k dacht al dat die grond me bekend voorkwam ;)</p>
