The height for Market East is great! The design needs something...anything...to spruce it up. But from the quote below, it doesn't seem very likely.
"Carefully crafted by New York’s Stantec Architecture to defer to the existing Lit Brothers structure, the tower would be set back 180′ from Seventh, Market, and Eighth Streets; its façade would primarily consist of white and gray hues, to intentionally not distract from the Lits complex."
