I have a 10X20 canopy that I bought at sams whenever my truck caught on fire. I knew that I was gonna be doing a lot to the truck and needed somewhere to keep it from getting rained on and so that I could work on it when it rains. Anyways that thing has last about a year and a half which surprised me since I only paid $175 for it. When that hurricane came through a couple months aog the damn thing got blew over and bent up the some of the poles and stuff. I was able to stand it back up and fix it to where it would work. Well since then it has blown over about 3 more times and today was the last time. A couple of the poles have broke compltely from bending back and forth so I am thinking about building a shop. I went a while back and got some prices and to do it out of wood would be pretty expensive. I want atleast a 15X20 whatever I do. It will not be a concrete floor but later on I will add the concrete floor and maybe add on. I was told to go to a metal place and get drilling stem for the poles that go from the ground to the roof and use cover sheet for the roof and walls. What else should I ask for to get it built cheaper. I know a couple people with welders and cutting torches so we will be able to put it together ourselves but I just need to buy the materials as cheap as possible. Also how much do ya'll think that a 15X20 open on both ends would cost to build? I am just wandering if I am looking at $500 or $1000.
