from the outside, i think either looks fine. it seems like the biggest difference would be with opt a, you would have a larger room upstairs - and usually people want more space and not less.

Consider altering the choice of window and roof line for option B thereby choosing the path of least resistance (and cost).

Respectively, with this plan is you may be able to pass a small walk out on the addition that could connect with any back decking.

I propose extending the roof to emulate the end point of the garage roof. Then offsetting the window center line to the garage.

I would choose option A. My eye would always be going to the window over the garage and the vertical straight line on the right side and the indented line on the left. If Opt. B, I would move the right wall over the garage to match the left side indent, then center the window over the garage door.

Option A is much more clean. They do not have to replicate the hip ridge on the overhang, they can make it end flush with corner and have a birds box. I can see why they have the options, its because of the outside corner and garage overhang transition. I do not know the extent of your 2 story reno, but maybe ask your builder about not bringing the overhang across the garage or at least explore a rendering without. It will give the house a lot more height. It may not be able to be done because the depth of your existing 1st story cladding (brick, stone) but you could change that also.

I have to agree with all of what Barbara Griffith says.

Thanks for all your comments.

To help with your questions, I have attached the other angles for the design options, but apparently the quality of the photo is terrible. I can try to upload it again when I get home.

Here is all 4 sides of house:

Again, any feedback is always appreciated!

Ok, I tried to obtain a better quality shot - here are the 3 remaining sides - still blurry, but slightly better.
