There once was a lady who wanted a maid's room to be transformed into a pied a terre for two.  I built an ebonized ash platform for two mattresses.  The headboard of one is the side of a clothes closet.  There is a place to sit by a window for a cup of tea, and lot's of shelving for the electric kettle and linens.   The old bathroom was tiled in limestone with deep storage for towels and tissues.
