Optimum Small Shop height design?

Don't skimp on space for overhead door to transition from vertical to horizontal. "Low head" tracks (tight curve) are available and work, but for long term functionality, the geometry of a "normal" track is a better choice.

Are you making the addition line up with the walk through door? In your picture, it looks like you have it set back to be flush with that door instead of the other, existing garage doors.

Yes... the reasoning for the set back of 4 feet is to reduce the blockage/maintain the view of the front of the house. Unfortunately I am severely constrained by my terrain and existing structure and I am trying to minimize the rework/tear down to keep the cost to a minimum. If money grew on my trees... another story. Here is the footprint showing the shop addition plan view.

I recommend building a hoist A frame separately. Leave the building out of the equation. The 2200 lb hoist from northern tool is really good. I lift 900 lb bobcat attachments with mine all the time.
