Pics Belly.....we need pics. Do you have an overhead aerial shot of your house. I can see either one having it's advantages over the other, but you also want to consider how it would look on the property.
I could, and maybe will here shortly take a couple pics of the garages the next road over. One is a brand new pole barn, but it is in the guys front yard, and the other is a mammoth huge gambrel roof barn that takes up the guys complete property in the rear. Another just built a 4 car garage that does look decent where it's at, and the last one is when the houses being built had restrictions. A sort of Country style HOA. The guy wanted to build a separate detached garage but was not allowed, so he added a garage on the opposite end of his house from his other garage.
So you want to stand back and look at the aesthetics of things along with the size. Stand back and take a pic of your house, then overlay a paper with a scaled size of the garages you are considering. Do it both from the front of the house, possibly what you see coming down the road, and lay it out on an aerial shot.
My garage is 28x36 with a 6' overhang front and one side. I wanted a space to work one side of the garage so my garage doors (2) 9x7's) are offset to one side.
If I were to do it over today, I would have turned the garage 90 degrees so I could have had a lift in the back corner. But at the time, I did what was affordable to us, never thinking about life changes, like going on disability, so my needs have changed. So you want to look ahead some also. But I can change my mind worse than a woman at times too.
