Description

A Private Indoor–Outdoor Oasis in the Sky More than a penthouse—PH 6/7 at 205 W 89th St is a private retreat where indoor–outdoor living defines the experience. A Saltillo-tiled walkway guides you to your residence, which opens onto a sprawling roof terrace that feels worlds away from the city below. Here, every season invites its own rhythm: long summer evenings with friends, crisp autumn mornings with coffee, or quiet winter nights under the stars by the fire inside. The terrace seamlessly extends into the interiors, where natural maple floors, seven skylights, and open, sun-washed spaces blur the line between inside and out. Designed as a combination of two residences, the home unfolds with remarkable flexibility across two wings. The north wing welcomes you with a relaxed open-concept living, dining, and kitchen space anchored by a wood-burning fireplace—perfect for cozy nights in. The tranquil primary suite, complete with ensuite bath and walk-in closet, ensures privacy and comfort, while a guest bedroom and additional full bath complete the space. The south wing offers endless versatility with four additional rooms, a second fireplace, two full baths, and its own private entrance—ideal for guests, creative pursuits, or a more secluded retreat. An oversized laundry and storage room with sink adds a layer of everyday practicality. A particularly appealing idea is to convert much of south wing into a sumptuous primary suite, complete with 2 separate ensuite baths, a 12'3" x 9'5" walk-in closet, and a sitting area with a fire place. See the alternative floor plan. (As usual, any renovations would first need board approval.) Life at Astor Court, a 1916 Charles A. Platt landmark, balances elegance and convenience with a beautifully landscaped English garden, roof deck, fitness center, playroom, full-time door staff, and pet-friendly policies. This is penthouse living redefined—an indoor–outdoor oasis in the very heart of Manhattan, where privacy, light, and space create a rare sense of ease high above the Upper West Side. 2% flip tax paid by buyer.
