This would work, bed could also be couch with just adding pillows. Add bathroom & kitchen, MY NEW HOUSE! :) The Ovida tiny house, a 160 sq ft vacation rental at the Getaway House resort north of Boston.
love log cabin / with pot belly stove Good idea if no heat present during winter. (We cooked on our stove and heated our house & water for showers/cleaning, one winter when we were w/o electricity for 9 days.
