Combined into a single, one-of-a-kind residence, The Royale East at The Rittenhouse Plaza offers 3,420 square feet of bi-level living above the storied Rittenhouse Square. Fully reimagined by architects Kass & Associates, with interiors by Spogue Kitchens and Baths and construction by Weaver Luxury Living, this 4-bedroom, 4.5-bath home is a rare fusion of pre-war grandeur and modern craftsmanship. Of every residence surrounding Rittenhouse Square, few — if any — are as visible or architecturally distinct as this one. The double-height arched window is a landmark unto itself, peeking above the treeline and visible to anyone in the park below. Spanning more than 40 feet along the Square, this residence has a genuinely impressive presence on the park. Unlike the typical high-rise arrival, this residence welcomes you through a true entryway — the kind you'd expect in a townhouse or single-family home. From the moment you step inside, your eye is drawn through a beautiful sightline framing the great room's signature arched window and park views beyond. The great room announces itself immediately — spacious enough to serve as both living and dining space, anchored by an 18-foot ceiling, a majestic arched window framing Rittenhouse Square, and an original decorative fireplace with marble surround. Double arched doors on either side open onto private balconies overlooking the treetops and skyline beyond. The residence offers both east and west side terraces, each with its own character and light. On the east side, an elevated section rises above the rest of the outdoor space — a private perch overlooking Rittenhouse Square with sweeping views. It may be the single most dramatic spot on the entire park to enjoy a morning coffee, a good book or an evening drink. The kitchen is outfitted with a Wolf, Sub-Zero, and Cove appliance suite, custom Artcraft cabinetry, and leathered granite countertops and slab backsplash. An oversized island anchors the room. Just off the kitchen, a space currently used as a sitting area and family room is generously sized enough to accommodate an 8-person dining table beneath its coved ceiling. The first floor is home to a spacious primary suite — that features a spa-like bathroom finished in floor-to-ceiling marble, with a soaking tub, a step-in shower, a dressing room with custom built-ins, and a laundry room with a full wall of cabinetry. The primary suite sits on the first level so that day-to-day living can be entirely contained to a single floor. A marble powder room completes the first floor. Upstairs, three additional large bedrooms each come with a tastefully renovated ensuite bath finished in floor-to-ceiling marble. For a buyer who doesn't need four bedrooms, any of these rooms lends itself equally well to a secondary living room, home office, or den. This level also features a sitting area overlooking the great room below, and its own washer and dryer. Oak floors run throughout, complemented by fire sprinklers, multi-zoned HVAC, and AcoustiBlok soundproofing. A deeded street-level parking space at 2020 Walnut Street is included with this sale. Built in 1925, The Rittenhouse Plaza is a striking Art Deco building on Rittenhouse Square, amid the latest trending restaurants, casual eateries, upscale shopping, business district — including a brand new Equinox next door, the most luxurious gym brand in the country. Residents enjoy 24-hour concierge service, a lush courtyard garden, and immediate access to the very best the city has to offer. The building is meticulously maintained. The monthly co-op fee INCLUDES REAL ESTATE TAXES, Fios cable and internet, steam heat, water, sewer, and building maintenance. Two Floors. One Extraordinary Penthouse. An Iconic Square Address — a collector's piece, one of a rare few whose exterior is unmistakable, from the shade of the park below to every window that looks out over it. ** The Last 6 photos are virtually staged **
