Growing up, my aunt and uncle lived in a house with this layout. I still love it. The differences in their layout is that the "workshop" was indoor space and was my aunt's mudroom, pantry and held the deep freeze. Also, instead of a main bathroom without a window they had a longer narrow bathroom and the master half-bath was beside the closet (so smaller and pushed forward into the bedroom a bit).
