About This Home

As of December 2025

Rare opportunity to make this spectacular fountain facing 2 bed Union Park penthouse your next home! Enter the oversized living room and your gaze will be drawn to the dramatic wall of windows that extends across the breadth of the space, with the full expanse of glass complimented by skylights that wrap onto the ceiling. The LR/DR area is further enhanced by custom built-ins, hidden storage, and integrated speakers. Hardwood floors and designer lighting throughout the home. The cherry-wood kitchen by Payne Bouchier features black granite counters, Sub-Zero and Viking appliances, and light-blue ceramic pavers. Yet another of 9 skylights anchors the kitchen, this one fabricated in stained glass by South End artist Jim Anderson. The marble-clad bath features a heated Jacuzzi tub and blue-glass detailing. 2 park facing BRs, including a bow front primary with bucolic views. Upstairs, a head house opens to a private roof deck from which the full 360-degree skyline panorama can be enjoyed.
