This set up would be so easy to make. First, clad the wall in beadboard, or panelling. Then, hang inexpensive, unfinished upper cabinets. (You can find them at furniture or building liquidation warehouses.) Then, it's really just a couple of boxes with a shelf in them for the seat. Next, use crown molding across the top and then paint everything the color of your choice. Finally, adding coat hooks and cabinet door hardware are the perfect finishing touches.
