Description
307 s. chadwick street is a rare chance to own a masterfully designed duplex tucked on one of center city’s most charming, historic blocks. once a 19th-century carriage house, this architect-owned residence was transformed over five decades by frank weise into a bold statement of mid-century and postmodern design.
the striking façade fuses a kahn-inspired brick center with a dramatic copper-clad mansard roof and cantilevered metal cornice—where even utilitarian features like the original hoisting boom double as sculpture. restored and updated by weise’s heirs, this home is both a time capsule and a modern masterpiece.
configured as a duplex with separate entrances, the lower unit—weise’s former studio—spans three levels plus a basement. soaring 16’ ceilings, slate floors, a floating staircase, and the iconic honeycomb window wall make this space unforgettable. a kitchenette and half bath add flexibility for creative or live/work use.
upstairs, the private residence is a sun-drenched sanctuary with dramatic volumes, a chef’s kitchen, guest bedroom, and a top-floor primary suite offering 360° views of the city skyline. the upper lounge includes laundry and access to a potential roof deck.
with three bedrooms, 1.5 baths, and a private carport, this one-of-a-kind home offers style, function, and flexibility just steps from rittenhouse square.
a true architectural gem—perfect for live/work, multigenerational living, or a savvy investor.
