A historic 19th-century carriage house in Rittenhouse Square, designed by renowned Philadelphia architect Frank Weise, is now on the market for $3.5 million. This landmark home seamlessly blends classic and modernist design, making it a rare gem in the city’s luxury real estate market.
Weise, a key figure in Philadelphia’s architectural evolution, purchased the home in the 1950s and transformed it into a live-work space in 1966. The lower floors served as his studio, while the upper levels became a living showcase of his modernist vision.
Featuring a brick facade with arched windows and an innovative three-story mansard-style roof, the property is described by listing agent Franz Rabauer of Kurfiss Sotheby’s International Realty as “a work of art.”
Now a designated historic landmark, this one-of-a-kind home offers a rare opportunity to own a piece of Philadelphia’s architectural history in one of the city's most sought-after neighborhoods.

A striking spiral staircase with multicolored inlays winds through this meticulously restored modernist townhome in Rittenhouse Square. Featuring double-height ceilings, expansive arched windows, and a sleek gas fireplace, the residence offers a unique fusion of historic charm and contemporary design.
Originally transformed by renowned architect Frank Weise, the home was later fully restored by his daughter, Andrea Hemmann, and her husband, master carpenter Mark Gallini. Their renovations included HVAC upgrades, metal restoration on the mansard roof, and a full modernization of the space. Previously serving as both a private residence and design studio, the property embodies sophisticated live-work luxury.
Perched above the surrounding rooftops, the townhome delivers breathtaking city views while maintaining a sense of secluded elegance—truly a sculptural masterpiece in the heart of Philadelphia.
