This great guest house was designed by Wayne F. Tjaden, he was tasked to figure out how to take a awkward space of 100 square feet with 13.5 foot high ceilings and make it a home away from home. The end result is pretty amazing and the re-purposing of an old mill reduces its impact.
Here is what he had to say about the process of design:
I was inspired by the challenge of converting a 200 sq.ft. former factory restroom plus 100 sq.ft. of an adjacent corridor, all with 13 ft. ceiling, into a guest apartment for the owner/architect’s live/work loft on the floor directly above. To solve the problem, I introduced diagonal walls, at aspect ratio of 1:4 separating the space longitudinally into principal living spaces and support spaces located adjacent to existing plumbing services. Then, I suspended a sleeping mezzanine within the 13 ft. tall space. The diagonal walls create forced perspectives which enhance the perception of spaciousness and the floating mezzanine allows the spaces to be appreciated as parts of a single whole.
