Graciously scaled and filled with natural light, Residence 17A at 40 East 84th Street is a beautifully proportioned four bedroom home with expansive entertaining spaces, four private terraces, and sweeping open views to the south, west, and north.
The residence offers a thoughtful and highly functional layout with generously scaled rooms and an easy flow between entertaining and private living spaces. The living room, dining room, and primary suite all open directly onto private terraces, where sweeping open views and multiple exposures fill the home with beautiful natural light throughout the day, creating a remarkable sense of openness rarely found in the neighborhood.
Privately situated apart from the entertaining spaces, the bedroom wing is designed with both comfort and practicality in mind. The primary suite features an en suite bath and direct terrace access, while a generously scaled secondary bedroom enjoys its own en suite bath and private north facing terrace. Two additional bedrooms are connected by a Jack and Jill bath, and a separate office or guest suite just off the kitchen provides exceptional flexibility for modern living.
The home’s four private terraces create a seamless extension of the interior spaces and offer multiple vantage points over the surrounding cityscape, lending an effortless indoor outdoor quality to the residence.
