Hey Ken, best advice I can give is map out your plans on how you plan to arrange the coming accumulation of stuff and more stuff !

The more space you have the more you tend to spread..
First thing installed was a 32' X 4' X 10' high section of pallet racking..
Then my work benches, tool boxes (I'am a tool freak) air compressor,etc,etc.
I really wish that I had documented over the years how things got rearranged
to make more room for the stuff that just keeps coming.
We need to have shop updates once a year..

One thing for sure you will be spending more time out there than in the house.
Hope you did not mind me cleaning your pics up...
