The banner above the entrance says “Brighter Living” and the building is living up to its new name, literally. This is the Luminaire Gramercy. It was formerly known as Post Luminaria. Developer Ben Shaoul recently acquired the property and is in the process of converting it from rentals to condos.
I'm guessing the blue spotlights placed in most of the rooms are in vacant/unsold apartments to draw the attention of passersby. They sure got my attention!
