I installed three 10x10 doors and love them. Most people never store anything against the walls with doors anyways. I could get a 24' enclosed trailer in my garage. Also, i installed scissor trusses with 12.5' walls. It's more than enough clearance for my two post lift but it's alot to heat.

One thing I'm sorry I did was use trusses, I should have had the roof stick built so I could have storage upstairs. I can store small stuff but it would have been better to have a full floor for more storage.

jackshaft garage door opener, 220v outlet, plenty of lights, 12' ceilings, epoxy floor

Ditto on the trusses. Allowed my friend and I do do the roof quickly by ourselves but the room would be preferable. I have 10' ceiling which are barely adequate. My brother did 12' which is best. I have 100amp service which is fine. I have my 4-post in the side bay and haven't ever wanted it different.

Ditto on the larger garage doors. I'd place the lift in the end bay so it's out of the way but leave some room along the wall side. I have regretted not epoxy coating my floor before moving in the garage. Lot's of high output lighting. numerous 220 outlets and I'd pex air lines behind the walls and enclose the compressor. Don't forget the air conditioning!

i have a 14x26 bay with 10 ft walls and scissor trusses that give me just over 14 ft in the center which allows me to put my fullsize 2500hd on the rotary 4 post and lift to full height with plenty of clearance
