I really like the exterior design of this Tiny House on Wheels. It would allow for sleeping lofts on each end and the kind of back porch I envision. The back porch extension could provided needed space to stow outdoor items during transit.
they have an option that sits over a garage! House in a Box: The Cascade.I don't think any other time I have pinned this house (grin!) Ihad the floor plan as well as the square footage. I do love this cottagey looking exterior!
House in a Box: Move fireplace to livingroom/porch corner and make a passthrough fireplace. No up stairs - just tall ceilings with windows for light. Wrap porch all the way around to bedroom and add french doors.
