Hi Mark,
Sounds like a fun time......enjoy it!
My suggestion is not the slightest bit technical, but comes from
experience. When you are laying out your shack, make it
twice as big as you think you want it to be now! The same
thing goes for building a workshop, garage, etc.
Good luck and I am certain you will find a wealth of technical
advice from these wonderful folks.
Merry Christmas and Happy New Year and Happy House Building
