“With a plan-to-height ratio of 1:24, compared to 432 Park Avenue’s 1:15 ratio, it’s the slimmest of the pencil towers,” says Daniel Hilpert, Founder and Managing Director of real estate investment banking intermediary firm Equicap. “Built on a footprint of about 7,500 square feet, the 84-story tower has a very high loss factor. As it is typically the case for tall towers, the core containing the elevator and staircases can be up to 20 percent of its floor area, significantly reducing the sellable floor area. SDJ and SHoP have done a great job maximizing floor area by designing larger floor-through or multi-level apartments with an average apartment size of 4,492 square feet, approximately five times the size of an average New York City rental apartment.”
