So Ive just been trying to come up with plans for this space i have. I was thinking metal pvc, and then roll some plastic and a shade thing up and roll it down the pvc when i want shade or green room. But then the sides are completely open. Wondering what you guys think i should do. I dont have alot of money to spend on it but idk i can always spend money on stuff over time.

Its on a balcony on the back of the house. Damn thought i had the measurements of the spot but guess not.

Anyway any ideas on how i should get myself started off? Are there places that build custom green house kits? Thanks
