Overhead storage is really important. I hate having any
non-car stuff down by the cars! I also have a floor in my attic. Luckily, the pitch of my roof is very steep and I have over 7' in the center so I can stand up and walk around in there. I have a pull down stairway that I positioned to come down even when all my cars are in and parked. I also have a trap door with a hand winch positioned above so in the summer I can pull up heavy objects like my snow blower or car parts. At one time I had most of an unrestored Austin Healey 3000 stored up above!
I also have my heat and airconditioning units and ductwork up above as well as large stereo speakers that face down to the garage work area.
The trap door is just above in the picture here:
