Property Description

The Nancy Grace House — A Mid-Century Modern Landmark in Society Hill A rare opportunity to own an architectural landmark in the heart of Society Hill. Poised at the corner of Fourth and Cypress—front door addressed 400 Cypress yet also known as 318 S. 4th Street—this residence was commissioned in 1960 for Nancy Grace and designed by the celebrated Philadelphia firm Stonorov & Haws. With bold Mid-Century Modern lines, sculptural chimneys, and expansive walls of glass, the home embodies the firm’s modernist vision while harmonizing with its colonial surroundings through its brick construction. Recognized for its significance, it was added to the Philadelphia Register of Historic Places in 1999, securing its place as one of the city’s most distinctive residences. Set on a 23' × 70' corner lot, the home offers a rare brick driveway and courtyard that accommodate two cars while doubling as a private outdoor retreat. Inside, the first floor is designed for openness and flow: a glass-capped partition defines the living room from the dining and kitchen areas, maintaining a sense of light and continuity. The kitchen is highly functional, with granite countertops, custom cabinetry, stainless LG appliances, an oversized picture window that frames the courtyard, and space for four counter stools. Newly refinished white-oak floors run throughout, and a gas fireplace anchors the main living space. The second floor hosts two bedroom suites. The corner suite faces Fourth Street, wrapped in dramatic window walls and vaulted ceiling detail, with Lutron electronic blinds for convenience. The second suite overlooks the courtyard, offering exceptional privacy and a large walk-in closet. Bathrooms are updated with marble vanities, illuminated mirrors, and glass-enclosed showers. The finished lower level, complete with a third full bath, provides flexible living space—perfect as a media room, gym, home office, or guest suite. Fresh interior and exterior paint, combined with thoughtful upgrades, preserve the home’s mid-century character while ensuring modern comfort. Situated among cobblestone lanes and historic brick facades, this home enjoys one of Philadelphia’s most desirable locations. Beyond Washington Square and Old City’s galleries and restaurants, it is also just a stone’s throw from Three Bears Park, ACME, CVS, Whole Foods, and the lively Headhouse Square Farmers’ Market. 400 Cypress Street is more than a residence—it is a piece of Philadelphia’s living history: a modernist landmark commissioned for a remarkable Philadelphian, designed by one of the city’s most influential firms, and lovingly updated for life today.
