170 5th Ave Penthouse LUXURY PROPERTY AUCTION: 15-29 July. Accepting starting bids through 14 July. Starting bids expected between $6M-$9M. Earn an incentive by 14 July. Perched atop the storied Sohmer Piano Building-architect Robert Maynicke's crowning achievement on Fifth Avenue-this completely renovated penthouse commands an irreplaceable position adjacent to the Flatiron Building. Two grand foyers connect via a circular baronial limestone staircase, while more than 40 oversized windows and an 80-foot greenhouse-style expanse flood the open-concept interior with extraordinary natural light. The privately deeded roof deck and golden dome cupola deliver panoramic, 360-degree views encompassing the Empire State Building, Madison Square Park, and the Manhattan skyline. A corner primary suite with three exposures, a Waterworks soaking tub, and 35-plus linear feet of closet space completes a residence that is, above all else, a piece of living New York history. In a remarkable philanthropic gesture, all proceeds from the sale will benefit the Gorongosa Project in Mozambique, adding a meaningful legacy to this extraordinary offering. Property and opportunity details provided by seller or others; buyer to verify.
