Description

A Rare Duplex Retreat with Two Private Terraces in the Heart of Gramercy Welcome to a truly exceptional Gramercy home—beautifully revamped and designed with an effortless resort-chic sensibility. This striking duplex offers a rare combination of sophisticated interiors, central air, gracious indoor-outdoor living, and two private terraces totaling approximately 277 square feet. The expansive upper terrace spans approximately 236 square feet and feels like a private urban sanctuary. Mature plantings create a lush, established landscape with ample room for outdoor dining, entertaining, lounging, or simply unwinding above the city. A second terrace of approximately 41 square feet extends the home’s connection to the outdoors and provides an additional intimate escape. Inside, the residence is warm, stylish, and beautifully considered. Its two-level layout creates a wonderful sense of separation and flow, while the updated interiors and central air bring modern comfort and an elevated quality to the home. The result is a serene city retreat that feels both polished and inviting—perfect for quiet mornings, sunset cocktails, and memorable evenings with friends. Set in the heart of Gramercy, this one-of-a-kind home offers the uncommon luxury of substantial private outdoor space, flexible duplex living, central air, and timeless design—all within one of Manhattan’s most beloved neighborhoods.

Gramercy Park is one of New York City’s most storied and architecturally distinctive neighborhoods, centered around the only private park in Manhattan. The area exudes old-world charm with its gas-lit streets and impeccably preserved 19th-century architecture. While the park itself is private, the surrounding real estate offers a mix of historic brownstones, elegant pre-war cooperatives, and boutique new developments that cater to those seeking a low-traffic urban retreat.
