Planning a shop build, any suggestions?

Termites dislike penta treated wood if done right.
The oldest "pole Barn" I had built and have knowledge is a 55 x 120 indoor arena in Missouri. Still there and solid but they have NO termites there!! Built with solid 6 x 6 pole, NOT the laminated chit some try to use.
Just saying.
Farmers have used pole buildings every where and still do. They are just NOT fancy enogh for those that need prettier maybe.
Whatever I have NO hound in this race.
Sorry I have lived in Missouri for 30 years and there are termites here, had to have two house treated for them.
Sorry again, If you put wood in the ground anywhere it will eventually rot.
You cant beat a code compliant 2x6 custom framed building that is spray foamed insulated, the best long term bang for the $buck.
