given the hundreds of luxury residential towers across the globe with far brighter and more prominent cowns (and closer to hightest habitable floors, as well) than the subtle, lit-up small four seasons tree logo that was in all the renders, i think it's beyond a safe bet to say that there are approaches to applying that signage to 1 dalton in ways that wouldn't have impacted the interiors of the upper-floors. they were very reluctant to reply to the question in the first place, immediately removed the response, and have since said nothing publically about why the lit-up logo idea was abandoned. i take all of that as pretty compelling suggestive "evidence" that they simply cheaped out and decided not to do it. given the 9-plus months of plywood windows, would you truly be surprised that they effed-up this signage detail?
before anyone tosses out some variant of, "do you REALLY think the developers of such a luxe project would cheap out on some final detail like that?" i submit to you the still-incomplete (and never to be completed) roof of boston's "other" luxury residential tower. as with 1 dalton, millenium tower promised one thing, which was approved, and delivered slightly less. in both cases, i'd think the failure to deliver would be actionable and hopefully boston nuts up and takes both 1 dalton and MT to task.
