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 Cecil Baker, this limited collection of just eight luxury residences stands among the city’s most refined residential 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 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. Residence 301 offers 3,739 square feet of thoughtfully designed interior space and 272 square feet of private outdoor living, incorporating part of the original Dilworth House. Soaring ceilings, architectural details, and curated finishes create a seamless balance between historic charm and modern refinement. The layout features three spacious bedrooms, three-and-a-half baths, a family room, and a versatile den, ideal for everyday living or elegant entertaining. The open-concept design connects a generous living area, dining space, and a chef’s kitchen by The Cut, meticulously crafted in Italy. Imported cabinetry, porcelain surfaces, and top-tier Gaggenau appliances, including double ovens and a built-in espresso system, elevate both form and function. Each residence in The Dilworth House showcases bespoke kitchens and architecturally forward layouts designed to enhance natural light and views of Washington Square Park. The primary suite enjoys access to the private terrace, a custom dressing area, and a spa-inspired marble bath with radiant-heated floors, soaking tub, glass-enclosed steam shower, and dual vanities. Additional ensuite bedrooms provide flexibility for guest quarters, an office, or studio space — each featuring generous closets and refined finishes imported from Italy. Building amenities include a full-time doorman, residents-only fitness studio by Technogym, storage, and a state-of-the-art automated parking system that parks and retrieves your car with the touch of a button. Constructed with reinforced concrete, soundproofing, and secure access, each home also features Lutron lighting, two-zone HVAC, and smart-home integration. A 10-year tax abatement and low condo fees provide long-term value. Additionally, there is a rare opportunity to purchase a 504-square-foot ground-floor auxiliary space, ideal for a guest suite, office, or gym. With the option to add a full bathroom, the total potential living space expands to 4,243 square feet. Located directly on Washington Square Park in the Society Hill 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. The Dilworth House represents a rare opportunity to own new construction overlooking Washington Square Park— a home that honors its historic past while redefining modern luxury living in Philadelphia.
