This garage adaptively reused as a tiny house of 400 square feet is in the Mt. Tabor neighborhood of Portland, Oregon. It features a mezzanine bedroom, alternating steps staircase and plexiglass porthole in the mezzanine floor lighting the kitchen below, a typically well thought out detail.

from:   " I converted my detached garage to a nice 400-square foot house for my mother-in-law to live in. I was kind of impresario or “developer” for the project, which was rather more complex than 400 square feet might suggest, but the cool results (especially that dishrack :) made it all worthwhile.  It cost approximately $73,000, which includes permits, design fees, and city systems development charges. The architect was John Perkins. "
