Shop layout recommendations?

When I bought my house it had to have room to build my shop and extra garage . Set backs limited the width to 24' for the shop . I needed 12'3" clearance for the BendPac asymmetrical Twin post lift . To avoid engineering I kept the length to 34' . To get the height I needed we did a 2' concrete stem wall and 2"x6"x10' framing to to get the 12' plate height . To get the lift clearance I used scissor truss' .
For the lift I put 6" concrete in the area of the lift and 4" for the rest of the slab . Check with your lift manufacture for floor spec's for 2 post lifts , it will save your neck .

In the shop I added a 2 1/2' shelf along both sides of the shop and a 4' shelf across the front .
Also added forced HVAC to the shop and a ceiling fan over the forward area of the lift .
I added outlets 4' over the floor every 4' all around the shop on 4 circuits along with a 220v outlet for the welder . The windows on the side are mounted with the bottom at 63' above the floor , they are for light not looking out of . I also tied into the whole house Vacuum system , make clean up a breeze .

The Extra Garage is 24' x 28' with a 11' high door at both ends . The air compressor has its own compartment in the corner with 220v . The outlets are again 4' off the floor every 4' on 3 circuits . The HVAC servers the both the extra garage and the main garage .

The Main Garage is 28' x 40' with a 10'x28' bay separating the Extra Garage , and a 10'x20' bay separating the Shop from the main garage . The Main garage has a 1/2 bath room with a deep sink . I decorated it as a Texaco Station bathroom .
