Ok, beyond the bedroom (15' x 20') there is a 14' x 6' dressing room, lined with a regular closet (approx. 6' x 3') a small walk-in (4.5' x 4.5') a large walk-in (8' x 8') and a bathroom (9' x 6')--which means the auxiliary space is around 240 square feet, rivaling the size of the bedroom itself and some efficiency apartments I've seen. And all of the floor space is covered except for what my mom calls "pig trails."
