Hey everyone, new here! I'm creating a build for a balcony awning for my apartment. The build is roughly 66 in x 196 in in width/length, and then for height maybe 7 feet on one end and 9 feet on the other. My question is: 1) The floor is made of tile and I can't connect the pipes to anything rigid, should i make the base connect all around for increased support? I'm in the northeast so I'll get a range of weathers. and 2) Should I create more than beam support (i.e., not just the 4 corners) Thanks!
