A rare chance to own a newly constructed, four-story single-family home in Rittenhouse, 520 S 17th Street stands out for its timeless layout, refined finishes, and private outdoor spaces-all within the Greenfield School Catchment. Expertly crafted by esteemed Philadelphia builder Waybar Development and designed by A2 Design Group, this 4-bedroom, 3-bathroom residence includes a finished basement, garage parking, three private outdoor spaces, and a 10-year tax abatement. Enter through either the front door or the private 1-car garage into a tiled foyer area that leads back to the first bedroom with a full hallway bath and abundant storage. This level flows seamlessly to a spacious rear patio-perfect for outdoor entertaining or quiet relaxation. The next floor up houses the bright, open-concept kitchen and main living area, complete with room for both formal dining and a full living setup. Just off the kitchen is the second of three outdoor spaces-a sizable rear deck ideal for an herb garden or dining al fresco. The full-floor primary suite sits one level above for easier access compared to traditional top-floor layouts. It features a massive walk-through custom closet, dual vanities, and an oversized walk-in shower with dual rain heads. A laundry closet is conveniently located on this floor as well. The top floor includes two additional bedrooms, a shared en suite bath, and access to the full-sized rooftop deck-complete with expansive city views and a dry bar just inside for effortless entertaining. Throughout the home, thoughtful finishes include 10-foot ceilings, white iron railings, oak handrails, and wide-plank Bruce Silverwood engineered hardwood flooring. The kitchen is outfitted with fluted Timber cabinetry by Fabuwood, Taj Mahal quartzite countertops, a GE Cafe appliance suite, ceramic Tranquil tile accents, and a Sharp microwave drawer. Bathrooms are elevated with red oak vanities, subway tile walls, checkerboard or ceramic tile flooring, and Delta Trinsic fixtures in champagne bronze.
