About this home

A Union Park Dream! Soaring 15' cathedral ceilings and over 21' of interior width deliver rare volume in the South End. Perched above Union Park, this 2,340 SF penthouse duplex is defined by light, scale, and thoughtful design. The main level features a luxurious kitchen with premium appliances and sleek finishes, opening to an expansive living and dining area that easily accommodates a 10-seat table. Exposed beams highlight the dramatic ceiling height, while a gas fireplace adds warmth. West-facing window walls flood the home with natural light. A lofted den with a custom wet bar leads to a private roof deck, ideal for entertaining or relaxing. The lower level offers a park-facing primary suite with oversized spa bath, steam shower, and soaking tub, plus two additional bedrooms. Two deeded parking spaces, including one garage.
