This may not be the right place for it, as the building in question is "done" (apart from what I'm going to ask about, maybe), but I couldn't figure where else works better:
It was generally agreed that the little wind turbines at the top of 888 Boylston were silly and a meaningless nod (either the original shape or the "stand-up" vertical ones that went in) and of course them blowing over in heavy winds was a design flaw, *but* without wind turbines or whatever type or anything at all up there now, the "frames" for said turbines which remain atop the building look distractingly pointless and ugly.
So, my question -- after a longwinded buildup -- is: Are they ever replacing those mini turbines on the roof? Replacing them with something else that's purley ornamental? Doing nothing?
If it's the latter, then between 88 Boylston's stupid roof windmills, 1 Dalton backing out of the lit-up Four Seasons logo promised in the renders, and Millenium Tower opting to not cover the roof (again, as per the approved design), Boston is having a seriously lame trend of failing to execute the intended designs of highrises/towers with respect to "crowns."
It's bad enough that all but three or four highrises in the entire city have boring, flat roofs (or slanted, straight roofs -- exciting!), but all these minor ornamentations that add a TINY bit of "pop" to newer projects are failing to materialize. That'd mean that smart money would be on the lit-up crown on Winthrop Center never materializing either.
Chrisbrat -- when you say " all but three or four highrises in the entire city have boring, flat roofs " -- are you including largish antenna structures?
and of course what do you consider a "highrise" -- let's use the Emporis definition for Highrise "architectural height is between 35 and 100 meters..." and allow it to exceed the100m to be classed as an "Emporis skyskraper"]
Here's a partial list of Highrises with interesting or tops at least with some 3Dness - roughly by "height":
Pru -- top of the hub hat and antenna
"Ms Pru" -- the crown or tiara
BNY Mellon Center aka One Boston Place -- top hat
Two International Place -- Johnson dunce cap
Weather Beacon Hancock -- iconic top
Custom House -- the original non-church tower and clock
The Landmark at Federal aka United Shoe Machinery Building -- art deco in Boston
Landmark Center in Fenway aka Sears Warehouse -- late art deco in Boston
State Street Financial Center -- pseudo gothic
101 Federal Street -- pseudo medieval castellated
75 State Street -- gold crown
100 High Street -- wedding cake top
125 High Street -- trapezoidal frustum
50 Post Office Square aka New England Telephone & Telegraph [185 Franklin] -- iconic telecommunications Ziggurat
