What is the ballpark figure $$$ for the cost to build oneof those blinds?

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.

Notice the small round windows,when standing up stretching it is nice to be able to look out. Yea, I am short. Put at your eye level. Made the entry door bigger on my second one.
