Pre-2011 balcony enclosure

My co-op's board wants to destroy my balcony enclosure which pre-dates 2011, and which poses no public danger at all. 1 RCNY 103-04, allows my enclosure to stay, but the Board can't be bothered. The enclosure is so solidly attached, there is no way it could be removed without damage. I finally got a guy from the management company to come look at it today. He took some pictures and said "Yeah, I see why you're concerned." It's floor-to-ceiling glass with window panels through the level above the railing that slide up to open. Has anyone had a situation like this?
