Very neatly done, McG! I don't understand what Cheoy Lee was doing with that inner Teak frame. I probably would have compromised differently: new countertop, new port surround, but put it back.
NW, the board facings is good old nautical stuff. Looks good, easier to work through if there's a problem to solve behind. Seen on all sorts of boats, from yachts, to fishing schooners, to Herreshoff. Often spaced for ventilation behind on wood boats. Easy to do, too; the boards are often shiplapped, I presume so that the gaps are concealed and access behind can be had without removing the whole array from one edge.
