As I start filling up my 'new' 30x40x14.5' ceiling, in central Oregon, I can
honestly say it's the bare minimum size to work in and have anything
resembling a real shop filled partially w/equipment. I'm putting in a 8'
high storage loft on one end, 4x24 overall, with office, full bath,
washer/dryer below. A lift isn't a big deal unless you plan to work under
the vehicle a lot. Good lights (I installed 6 twin-8'-tube LEDs, 12K-lumens
each fixture), radiant heat source (or floor), and tons of outlets seem of
high importance.
