My hangarmate is building one in our hangar. This weekend I can measure his enclosed work area and the width of the airframe sans wings if no one gets to it before then.
He has built an enclosed work area that is air conditioned inside the hangar. It holds all his tools and the fuselage with (barely) enough room to work, but things like the parts delivered but not yet installed (interior, cowl, fairings etc) are in the loft above his work room. The completed wings are on a rack in the hangar. No engine yet. Just by looking at it, the work space appears to be a bit smaller than a 1 car garage.
