It would be 30 x30, moss green walls, white trim, medium oak laminate flooring, large white wall cabinets with glass fronts for my fabrics which would all be neatly arranged by colors and style, a 6x6 cutting table, a walk in closet for storage of bulky items, a row of counter with replaceable cut outs to fit all of my machines and a removable extension table to hook on the front edge of the counter so I could attach it when I am working on a heavy quilt or FMQ. My lighting would be daylight fluorescent and some incandescent lights. I'd have a large vintage look ceiling fan with no lights on it, I would also have electric outlets with 4 receptacles and built in surge protectors, a small laundry area with a washer, dryer, utility sink, and an ironing station. I'd also have a large antique Grandfather clock in the corner. No, I haven't really thought about it much at all...
