First, great looking garage, and nice toys.
Second, Hey! I am hoping to build mine the same way. I have a double lot, with my house on one side and a vacant lot next to it. The house is a 1940 craftsman house, typical build: narrow up front, long on the sides. Because of the way the lots and house are arranged, it would be a squeeze to access a garage from the side. But, I have a long and decently wide size to work with, around 35X60, so I am thinking of building a garage around 30 ft wide but a little more than two cars deep.
How much of an area do you have in front of the garage doors? I am thinking of making the access in the rear. Keep the neighbors out of my business, y'know?
