Built them 2 yrs ago but cost me around $225.00 then. Depends how elaborate you get. They are carpeted to cut down on noise, but I already had the carpet. The metal roof material was left over from another project. Had the paint. Some of the treated base wood I had left over from a construction project. Already had old office swivel chairs I used inside. Well worth the work and money though. Before building, when it is wendy, real coldor raining I went back to cabin.Now I stay out. The outriggers are old 2x4's and are there to keep it from possibly blowing over or prevent some trespassing punk from pushing them over. If it goes over I would have to take it back apart to get it back up.Youcould just use the 4x4 legs and cable to ground or bury the legs in concrete.
