 The new building would have the first nine floors occupied by a "vertical mall" similar to The Shops at Columbus Circle topped by an 11-story hotel and of high-end condominiums.The project would be completed by 2025 at the earliest and would face a park, created by razing a block of current buildings.The developers also planned to change the name to 660 Fifth Avenue, to avoid the diabolical association with the number 666.
