Oregon-based Ideabox, the company behind Aktiv with IKEA Portland, recently shared news of an expanded endeavor called Minibox.  Minibox is actually a series of “minihomes” built to RV and park model codes.  The tiny-house series has designs ranging from a 200 square-foot studio to a 320 square-foot one-bedroom/one-bath cottage.  And you can bet Ideabox will continue to plug all the green stuff inside.  Pricing for the non-wheel version starts at $42,500.
