no contracters plumbers or electricians here. I had a company pour the slab. Other than that I did everything with my own two hands. at times I had one or two ppl to help me hold something up while I got it where I wanted it. In the pic thats my dad he used his tracktor for a make shift scafold, my mom was the gofor. not in pic my gf helpin with paint, and my daughter. It took me way too long to build it because it was all out of pocket.
It's not the biggest but i built it, it's solid, and It's 100% paid for.
I just scored a 40' steel container with lights already in it. will make for nice storage
after I fix the floor in it.
