Just another suggestion. Are you building the garage as one big open area? If so consider constructing you a room to work in to keep the dust, dirt, paint off the remainder of the shop. I did a small, 16 feet 26 feet room to allow one car to be in on rotisserie. I also vaulted the ceiling to take some of the dead air space out and allowed the LED lights to be mounted on an angle. I am going to add four more of the lights one on each end and another in the middle on each side.
I wired the room so that I can have welder in there and all the lights are wired to the switches I do not have to burn them all if not needed. I have not built my door to close off yet it will have a foam seal to close off the area. Like you I am trying to remodel house also and go back and forth from garage to home.
I am also putting a floor on the work room ceiling joists and can store parts up there to clear out floor space. I have a 16' eve height.
The width of the room was determined by the maximum length that a 2" 12" pine framing could span without going to 12" centers or to a truss which is way more expensive.
I still have to put in a ventilation system. I could not do that while I was building it or would have issue with the inspectors. After you get certificate of occupancy you can do more work without them knowing.
I have found that one of the best work benches you can get is an old drafting table. The top tilts and it also has power to raise and lower so you can work sitting or standing. I got at one of the second hand stores for $10.00 and I use it every day.
The work room is also insulated so I do not have to heat the entire shop to be comfortable. You can see in the picture where the electrical conduit comes out of the floor to feed the work room. The wiring for the two post lift was also under the floor and I put thicker concrete under the posts for the lift. Maybe one day I will put a video slide show together showing the shop going up.
