15 Union Square W #31, New York City, NY 10003

Rooted in historic Flatiron and on Union Square Park, this full service, white glove condo marries an opulent past reimagined for the modern world. Originally erected in 1870 and dubbed “The Palace of Jewels” the building was the flagship location of Tiffany & Company. Today, this boutique condo is home to only 33 unique residences; each a precious stone to behold.

Unit 31, aka Penthouse 8C, is a designer duplex with 2 bedrooms, 2 full and 1 partial bathrooms, sprawled across nearly 2,000 square feet of interior living space with an enormous private roof terrace. Thoughtfully crafted interiors are flooded with natural light from 3 exposures, floor-to-ceiling windows, and soaring 11-foot ceilings.

Transition into tranquility through a formal gallery that provides ample storage for unpacking the day and arrive at the heart of the home where an expansive great room is flanked by a soothing fireplace on one side and balanced by a gem of a kitchen on the other. Custom interiors create an inviting ambiance for both relaxation and entertaining. The kitchen island is an anchor to gatherings uniting casual breakfasts and formal dinners alike.

At the rear of the home you’ll discover the private primary bedroom retreat that is graced with morning sun through eastern views overlooking Union Square Park. A tranquil en suite bathroom commands a symphony of relaxation enveloped in stone. A wet room hosts a cast iron clawfoot tub for daily detoxing and multi-angular double head shower for washing away and stresses. The windowed dressing room is just steps away to shroud yourself in the illumination of your morning experience.

When connection to the elements calls, answer it swiftly by ascending a private stair to a gigantic yet surprisingly intimate private roof terrace; a true luxury in New York. Nearly 1,200 square feet of outdoor space provides a serene escape above the city with ancient trees at Union Square Park just to your east, open sky views surround, and illuminated softly by The Empire State building to the north. Whether hosting gatherings under the stars or enjoying a quiet morning coffee, the terrace offers a seamless extension of your living space and endless opportunities for curated moments.

Downstairs a secondary bedroom retreat with windowed en suite bath and dramatic hallway powder room allow friends and family alike to elevate their perspectives and experience alongside your inevitably cultivated placidity.
