Step into a residence tuned to a higher frequency. Elevated above Rittenhouse Square, this 3,500+ sq. ft. masterpiece is a private sanctuary designed for pure sensory resonance. Reimagined by award-winning dMas Architects, this home was born from the meticulous combination of two units, earning an AIA Award of Merit for its architectural precision and emotional depth. Occupying the "sweet spot" of the 21st floor, the home sits at the perfect horizon line. Through thirty-six south and east-facing windows, the ziggurat architecture offers a rare perspective: high enough for total serenity, yet close enough to feel the heartbeat of the Square. Every inch is engineered to harmonize with the inhabitant. Hand-plastered walls and ceilings capture natural light, while Reglet trim and custom millwork allow walls to appear as if they are floating. Arrival is an immediate transition into light. The sun-filled entry provides deep, concealed storage and leads to a perfectly positioned powder room featuring hand-selected stone and a floating vanity. An expansive gallery provides effortless flow between entertaining areas and private suites. This central artery serves as a sophisticated space for art, anchored by floor-to-ceiling slabs of honed travertine and translucent quartzite. The great room features Travertine marble and walnut built-ins, transitioning into a professional Poggenpohl kitchen with Wolf, Sub-Zero, and Bosch appliances, a 175-bottle wine refrigerator, and a custom backlit quartzite wall. Positioned off the main living area is a sophisticated butler's pantry and bar area, a dedicated space with a separate sink for seamless hosting.Integrated seating nooks and a private library provide quiet clarity, while the primary suite is a true "home within a home" featuring a sitting room, dual walk-in California closets, and two full baths--one with a deep soaking tub and a glass wall overlooking the park. Within this private wing, dual home offices are housed in a custom-built architectural pod, offering a secluded environment for deep work. Functional additions include a separate laundry room with a washer, dryer, sink, and storage, plus large-format Italian porcelain and sapless walnut floors, an integrated A/V system, and custom electric shades. The footprint offers rare capacity for a third bedroom, easily accommodating a custom partition or moving wall system without compromising the open-concept resonance. The offering is further enhanced by dual storage units within the building, providing a substantial 'double' footprint for overflow. Enjoy five-star white-glove living with discounted access to Rittenhouse Hotel's world-class amenities--including Lacroix, Scarpetta, a full-service spa, and indoor pool. Located steps from Philadelphia's premier cultural attractions, amazing dining and the new Equinox Fitness Club. This is more than a residence; it is a rare synthesis of architectural craft and soulful sanctuary, calibrated to maximize the life you have built.
