I think they are right to do something with it. It's not fit for use inside, no disabled acess, it can't be used in the winter. There are no catering options. (arguably this could have been fixed if the Commissioners had been looking after the place for the last 20 years rather than letting it rot.).
But the plans they had drawn up weren't right. It was a kind of cheap looking hotch potch. I think a competition to find something really right for that spot - probably super modern looking but making the most of the amazing spot. And not ruining it by putting lots and lots of car parking in front of it (looking at you MNH and the parking at the Sound).
