There's a reason no one talks about redoing City Hall. It's because it does work... it's aged well and is a landmark we can all be proud of.
Symbolically, yes. Functionally, though, it's always been problematic; and yes, a lot of the problems come as a result of the architecture. Ask the people who work there.
If "nobody" talks about redoing City Hall, it's because (a) they know they'd have to swallow their grievances lest they be pilloried by the architecture/heritage police, and (b) it was already deferentially "redone" by KPMB post-mega-amalgamation, so it's not as "unfresh" as it was. But if this whole question had come forward a pre-mega pre-KPMB decade ago, the discussion re City Hall itself might take on a different tone, especially if "taken public" a la NPS today. Then as now, who knows the damage a well-meaning but underinformed vox populii web-discussion-board-type amateur may wreak in the name of proposed "improvements". (And remember, too, that a lot of the
intelligent spin for Metro Hall over City Hall as seat of mega-government was based upon functional reasoning--face it; in raw contemporary terms, Metro Hall "works better", euphemistic as that might sound.)
Why is there talk of redoing NPS? Because it's a shabby mess that's aged very poorly.
And as has been stated over and again, might the so-called poorly-aging shabbiness be more a matter of haphazard upkeep than anything? And perhaps any necessary "redoing" is more a matter of belatedly taking what KPMB did within and applying it without, so to speak?
Ultimately, NPS is no more or less "dysfunctional" than the building it serves as the integral forecourt for--and
integral as it is, it's no more or less beloved for/despite the fact. (It only seems "less important" because such spaces almost invariably play a misunderstood second fiddle to the buildings they serve.)
So, my "attempt at humour" is nothing more than a means of highlighting one of those many reasons why "qualified professionals" shudder at the amateurish so-called bright ideas perpetuated within forums like this...
