I believe this is the last item from the original house plan that had heretofore remained unfininished. In fact it had, until recently, remained unstarted.
The bar was primarily designed as a way to provide a screen to the backside of the kitchen stove. And, of course, it is a nod to the modern fancy of having guest hover over the kitchen while the host cooks.
The nearly completed project. Below the bar are 4 panels of perforated steel from Roy Manufacturing in Portland.
Just needs stools.
