Thanks!
The latest design (parallel to fence) was chosen as the least compromising, because:
1) Marginal intrusion into septic field
2) Ease-of-access/approach for vehicles (and less driving over septic field)
3) Hoist placed on right side of shop (with 3' clearance to wall) allows more frequent "servicing" to take place with easiest access
4) "Separate" large work area at rear
5) Man door on "front" so as to be visible from house.
6) Electrical Panel and Hanging Furnace located for easy trenching for electrical from house (trench to avoid septic)
7) Roof line more closely suits existing house roof line, and scissor truss makes hoist placement easier. Based on the Truss Drawings, I theoretically have 13.5' of ceiling at the ceiling peak, and with 11' walls I am still well under my maximum height.
8) Compressor will be placed outside the shop (compressor room is gone). Maybe trenched air from the house garage, or something else. This frees up some more room and removes some noise.
Was probably something else in the plan, too.
Windows on the left side would stare right at the golf course I back onto, and would not be easily visible from the house.
Windows on the right side (south side) would stare into the yard of the neighbour who doesn't share my vision or enthusiasm. These windows would also not be visible from the house. Well, ~my~ house.
