Personally, I would've preferred a soaring Art Deco style at North Station. Art Deco is what made me as a child awestruck by North Station. The subliminal reaching for the heavens affects that the old North Station, Madison Hotel and Garden presented to the world was an optimism that was anathema to old Boston at the time.The new Central Place in Sydney Australia is very un-boxy, and would have looked great at North Station. I like the base that was built along Causeway Street, but would have liked towers like these (instead of the two towers built plus the Avalon). Note: I horizontally flipped the image to better fit the positioning of the three towers at North Station.
Glass buildings, whether boxy or curved, certainly have their place in the varied buffet of interesting cities, but when they predominate, it just becomes boring. This would've been the perfect place for two towers with Chrylser Building type tops. And the new South Station Tower (originally a spire top) could have been a beautiful bookend situation. Instead, we'll be left with the same old Boston slab crew cuts.
The American architecture of the 1920's and 1930's used to exude an optimism of the future progressive world. Today, sadly, aims to a lower bar.
