New here! I am a DIYer and I'm looking to build a shed/garage on my property. I designed the structure but am wanting to see if anyone can give me input on the integrity of my design. Basically I just want to make sure my roof wont fall in and my walls can take a decent wind load as I am in tornado country.
The pictures attached show a 60x36 structure. 48x36 is garage and 12x24 is closed in shop. It's a single slope roof that starts at 14' at the front and goes to 8' at the back. Posts will be placed into the ground 4' minimum.
I am using 6x6's for the posts and sistered 2x12x12's for the beams that span 12'. I also added some 6x6 bracing along the outside walls to help. I plan on having a plywood roof with galvalume metal on top. Haven't decided on siding but I'm leaning towards a shiplap type siding.
But back to my original question, will this be structurally safe and sound. Is it overkill or do I need to add to it? Thank you in advance for your input!
