Perched atop one of SoHo's most coveted cast-iron condominium buildings, this extraordinary full-floor, 5th-floor loft at 47 Mercer Street is a rare offering that combines historic character, over 4,000 square feet of indoor space, and a spectacular 1,000-square-foot private roof deck with open sunset cityscape views. Spanning an impressive 50 feet in width with soaring 11-foot ceilings, the residence is flooded with light from 18 oversized windows across four dramatic exposures, including six south-facing windows that bathe the living spaces in sun throughout the day.

Currently configured as a 3-bedroom (convertible 4), 3.5-bathroom home, the layout offers exceptional scale for both gracious entertaining and comfortable daily living, with flexibility for re-imagined customization if desired. The private roof deck, featuring a glass-enclosed atrium, crowns the residence, offering a highly coveted indoor-outdoor lifestyle rarely found in SoHo-ideal for sunset dining, intimate gatherings, or quiet moments above the city.
