Could this bw the garage? I assume that this is a double garage with 2 doors and space for something, work space or guest space?, on the second floor. Looks like a little house with 2 garage doors in front. Gable inside shed dormer.
Garage Apartment Pictures - one level (existing garage) Flip image and this layout would work with direct entrance into house instead of "deck" and stairwell. Need better closet.perhaps use whole "wall" and make it a semi-walk in from bedroom
