Designing tiny homes and recreational vehicles is a real challenge; value judgements have to be made about the importance of each function. How much do you give to sleeping? Kitchen? Bathroom or living? There is only so much to go around. That’s why I have been impressed with the work of architect Kelly Davis, working with George Dobrowolski to show How a talented architect makes an RV look like a charming cabin in the woods and how a Talented architect tackles the tiny house and comes up with a mini gem. Now they are at it again with a slightly larger version, the Traveler XL, which raises some interesting questions about design, space planning and the choices we make.
