I am lucky enough to have a 30x40 shop behind the house. It seems to be full of something all the time. So this weekend I am adding a second floor to half of it for storage of spare parts and seldom used items that i dont want to get rid off. My wife has grand ideas to store her holiday decorations in the addition . I don't think that is going to work out for me. I am going to move my large air compressor to an outdoor place and build a cover or a room for it. It takes up 18 sqft that I could use for other things.
The new loft gives me 600 sq ft more to work with. It will only have 4' height on the edges, but is almost 8' in the center.
I would love to epoxy coat the floor ,but it most likely will never get done because I would have to move everything out and blast track or grind the floor to do it properly.
