Description

A minimalist masterpiece by Michael Gabellini, this exceptional Park Avenue residence is a study in serenity, scale, and refined craftsmanship. Bathed in natural light from four exposures, the home unfolds as a calm, beautifully proportioned living space where clean lines and a curated palette create an atmosphere that is both modern and timeless. Spanning approximately 3,500 square feet across six well-balanced rooms, the layout flows seamlessly, with open living and dining spaces designed for both relaxed daily living and elegant entertaining. Subtle custom finishes and thoughtfully integrated details enhance the sense of quiet luxury throughout. French plaster walls and ceilings, paired with continuous honed limestone flooring, establish a quiet, luminous backdrop. Designed with an art collector in mind, the residence incorporates floating walls, gallery lighting, and carefully considered sightlines for both intimate living and curated display. What truly sets this home apart is its extraordinary connection to the outdoors. Nearly 1,700 square feet of private terraces wrap the residence, creating a seamless extension of the interior living space. These expansive terraces—framed by open exposures to the south, west, and east—offer breathtaking views over Park Avenue, glimpses of Central Park, and the iconic Rosario Candela. Whether for morning coffee, quiet afternoons, or evening entertaining, they transform the home into a rare and elevated retreat in the sky. The dramatic living room, grand in scale and facing west over Park Avenue, opens onto two beautifully matched terraces. Adjacent, an open library—defined by bespoke glass and steel rolling doors—connects to a serene guest suite with a luminous ensuite bath featuring translucent glass walls. The library flows into a well-proportioned dining room designed for elegant entertaining, and a sleek stainless-steel kitchen. Beyond, a private office with a Murphy bed and full bath offers flexibility for guests or additional workspace. The primary suite with two custom dressing closets and a serene, spa-like bath with hand-carved marble sinks and softly glowing translucent glass walls. Minimalist in design yet warm in feeling, this residence is a true retreat—an elevated, light—filled oasis in one of Park Avenue’s most coveted address. Triple-paned windows ensure exceptional quiet throughout, enhancing the residence’s sense of calm. Every detail—material, proportion, and light—has been thoughtfully considered, resulting in a home that is as sophisticated as it is livable. Located at 785 Park Avenue, a distinguished prewar cooperative on the Upper East Side, residents enjoy impeccable service, a private fitness center, individual storage, a beautifully landscaped roof garden and a newly renovated Art Deco-inspired lobby. Offered in impeccable condition, this architecturally significant residence is a rare opportunity to own a true Park Avenue sanctuary—where design, materials, and expansive terraces come together in perfect harmony. 50% Financing Permitted; 2% Flip Tax paid by buyer; Pets are welcome. Co-exclusive.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
