The container is 40ft. It is 40x20 ft. The total cost of the frame and the 5"x 5" steel plates that I welded the post to is around $1700.00. The decking was $225.00. The roof metal was salvaged from a garage (metal was faded after 2 years so the metal company replaced it) I was the successful bidder for that job. It paid $1800.00. Not bad. Thanks for the compliment on the arm. It will be handy.
