Garage ideas and tips.

Hey all. I am in the process of planning a new garage build. I live in town and have a maximum size of 750 Sq ft I can build. I have lots of yard to use and currently only have a one car. My driveway runs directly by the side of my house now but doesn't really give me access to my back yard. What kind of options do I have? What dimensions can I maximize my Sq ft with? I am considering something like a deep tandem with a garage door on both ends just for air flow and easy of moving stuff around.

I included a shot of my property from Google. You can see the arrangement of the house to garage.

is there a height limit? If not, go with as high a wall as you can afford and like. If you can, 11-15 ft. Will allow you to install a lift at some point and the added height will help air flow thru. Lowest I've seen for most 2 posts are 11 ftish.
