I have a space that's about 10' x 10' at the southwest corner of the house. Because of its location, the east side of the space is blocked by my house, same for the north side. The ground is covered with colored concrete, save for a 4' diameter circular portion where a stone fountain currently sits on dirt. I have a bunch of plumerias growing in-ground around the fountain. In the winter months, the south and west stucco walls get pretty warm during the daytime and stay warm longer after nightfall, so the trees in this space are not affected by the cold temps so much.
I'm contemplating putting up a semi-permanent GH that's at least 10' high. I THINK I can convince my wife to remove/relocate the fountain from the center spot, thus freeing up more planting area.
I'd put up 4 large posts that can be moved out of the way when I disassemble the GH in the spring. Can I buy the support frames and panels and assemble the GH myself, to the size that I need? I could build the support frames myself with 2x4, 2x2 woods, but non-wood materials are probably much better. Not sure if I should go with PVC (are they strong enough) or something metallic? What type of panels should I consider, glass or polycarbonates? I'd definitely want a motorized window of some kind to open during the day if the indoor temps reach a certain point. It's a must that the GH be not too difficult to assemble and disassemble (it's not staying up year round). I'm sure I'm missing a bunch of important considerations, so whatever you guys see, please point them out. Thank you!
