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.
I love a well designed mid-century modern home, like this one – especially with this many plants. The green against the leather couch, the art on the wall and the golden pendant jus go so well together.
