Be nice if the post lift was close enough to the raised loft that the lift could be used like an elevator to raise awkward items into the loft.
I'd have the lift in line with a garage door so it is easy to get on and off.
How about adding a floor drain and having a small indoor car wash/detail area?
Sink the scissor lift in the ground so you can drive lower cars right on it with out ramps.
Also make a plywood cover for the scissor lift so it can disappear when not in use.
I'd think one lift is enough.
2 lifts sounds life too much work.
Need a dedicated wall for the big screen too.
Add some skylights.
Nice window locations so you can work in the garage with the doors closed.
I'd have the garage doors face east so the afternoon hard sun is on the back of the building.
My 2 10x20 roll up doors face west and are hot as pizza ovens in the summer.
