Did not use any plans, had a rough sketch in on paper, My brother is a contractor he has built many larger buildings. He helped with labor and layout of the building. Knew I needed a 8' high door and wanted the door off center so I could store implements and have access to
the tractor without having to move anything.
The reason it is 16' wide and 24' feet deep with 9' walls was to reduce the amount of wood wasted. To keep the cost down. Lumber comes 8', 10',12'.
The trusses ordered from the lumber yard, sheathing comes 4'x8' sheets same for the plywood for the roof.
In the end I took all the scrap from building the entire project to the dump and the scrap only weight 100 pounds.
The total cost with the cement floor was just under $8000 and that included paying my brother his hourly wadge.
The siding is Smartsiding composite panel siding It has a 5 year nu-painted warranty and a 50 year painted warranty.
I used my tractor with the backhoe to dig out the foundation. Used 4000 psi cement with fiberglass mixed in.
It was not hard to build, it was only the two of us doing all the work. I have more pictures of it being built if you are going to build something let me know and I can post them and answer any question you might have.
