I drew this up using some free sketch app. The placement is along my property line which has an angle so in order to honor the setbacks I couldn't make it symmetrical. The larger side is 30ft deep, the shorter side is 20 feet deep. The larger side is for my truck and will have a 12 ft door. The other side will host our date car and has an 8ft door. Both will have 8ft openings to allow for my truck to fit.

I do live where it snows but it's usually not that bad. I'm not sure if it's worth heating the garage.
