An Iconic Location Built for the Visionary. Introducing The Dilworth House - a masterful fusion of architectural heritage, elevated design, and modern sophistication overlooking Philadelphia’s iconic Washington Square Park. Developed by Astoban Investments and brought to life by CBP Architects, the award-winning firm originally founded by Cecil Baker, this limited collection of just eight luxury residences stands among the city’s most refined offerings. Rooted in the legacy of Mayor Richardson Dilworth, who helped lead the revitalization of Society Hill, The Dilworth House pays homage to its past with stately Colonial Revival architecture by G. Edwin Brumbaugh, echoing the grace of Dilworth’s original 1957 mansion while embracing the craftsmanship of today’s luxury living. Behind a gated, professionally landscaped entry, residents are welcomed into a world of privacy, sophistication, and quiet grandeur. Residence 701 spans approximately 4,500 sq ft and features a 220 sq ft terrace facing Washington Square Park, with sunset views to the west and eastern exposures across the east wing. A private elevator opens directly into a gallery-style foyer leading to expansive living and dining areas framed by floor-to-ceiling windows and wide-plank European oak floors. The kitchen by The Cut, meticulously crafted in Italy, integrates imported cabinetry and porcelain surfaces, equipped with top-tier Gaggenau appliances, including double ovens and a built-in espresso system. The primary suite enjoys direct terrace access, a custom dressing area, and a spa-inspired marble bath with radiant-heated floors, soaking tub, glass-enclosed steam shower, and dual vanities. Four additional ensuite bedrooms provide flexibility for guests, office, or studio use, each offering generous closets and refined finishes imported from Italy. Building amenities include one of the most beautiful lobbies in Philadelphia, a residents-only fitness studio by Technogym, storage, and a state-of-the-art automated parking system that allows you to park and retrieve your car at the touch of a button. Residents also benefit from reinforced concrete construction, soundproofing, secure access, Lutron lighting, two-zone HVAC, and smart-home integration. This architecturally significant development offers expansive private terraces — including some of the largest penthouse terraces in Philadelphia - for seamless indoor/outdoor living and panoramic views of Washington Square Park and the Delaware River. A 10-year tax abatement and low condo fees add meaningful long-term value. Located in the Society Hill / Washington Square district, residents are steps from Talula’s Garden, Zahav, Morimoto, and Old City’s cultural venues, with easy access to I-95, I-676, and 30th Street Station. One parking space is included; an additional space is available for purchase. The Dilworth House represents a rare opportunity to own new construction directly on Washington Square Park, a residence that honors its historic past while redefining modern luxury living in Philadelphia.
