Ugh, what scum. I walk past the building at the NW corner of 5th and 43rd twice a day going to/from work (in a nearby, lame all-glass building). It is beautiful. Really, truly beautiful.
Across 43rd Street from it sits what is in my opinion not only (1) an ugly choad of a building and (2) a horrible harbinger for all of the despicable all-glass, all-right-angles boxes to come, 510 Fifth Ave.
That glass-box choad is landmarked. 516 Fifth is not, despite being actually an old, historic building; actually having strong aesthetic appeal; and actually being built in a style, and with materials, that will never be used again. 510 Fifth, on the other hand, is the most easily imitated POS the mind can conjure.
This blows the mind.
