An Iconic Location Built for the Visionary. Introducing The Dilworth House - a masterful blend 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 the legendary Cecil Baker - this limited collection of just eight luxury residences stands among the most refined residential offerings in the city. Rooted in the legacy of Mayor Richardson Dilworth, a visionary who helped lead the revitalization of Society Hill, The Dilworth pays homage to its past with stately Colonial Revival architecture by renowned architect G. Edwin Brumbaugh. The building echoes the grace of Dilworth’s original 1957 mansion while embracing the innovation and craftsmanship of today’s luxury living. Behind a gated, professionally landscaped entry, residents are welcomed into a world of privacy, sophistication, and quiet grandeur. Interiors are thoughtfully designed with custom millwork, soaring ceilings, and elegant, curated finishes. Expansive private terraces - including the largest penthouse terrace in Philadelphia - offer seamless indoor/outdoor living and panoramic views of both the park and the Delaware River. Each residence features top-tier, bespoke and timeless kitchens by The Cut with Gaggenau appliances, and architecturally forward layouts designed to elevate everyday living. Building amenities include full-time doorman service, storage, a residents-only fitness studio, and a state-of-the-art automated parking system that allows you to park and retrieve your car with the touch of a button. A full 10-year tax abatement and low condo fees add meaningful long-term value.
