Top 4 feet of my plywood bookcase have been mocked up. I still haven’t attached everything, but so far I’m liking the look. This week I’ll attach the remaining boxes, caulk and putty were needed and add some touch-up paint. Then next week I’ll start the ladder which will attach via rolling track directly to the ceiling above the bookcase. (Sorry pics are so bad, they were taken with my iPhone in a rush this morning.)
