Grand in scale and extraordinary in detail, Unit #401 in the historic Bank Building pairs old world craftsmanship, modern updates, stunning architecture, and front-row views of Philadelphia history in a truly exceptional residence. This single-level condo offers 3 bedrooms, 2.5 bathrooms, and an open, airy layout thoughtfully divided among three distinct wings. Constructed in 1859 along what was once Bankers Row, The Bank Building makes a commanding impression with its stately facade, arched windows, intricate stonework, and distinctive cast-iron entrance. A private lobby and attentive doorman welcome the building’s few residents, while an elevator carries you right to #401’s towering French doors. Stepping inside the foyer, you’re immediately captivated by the magnificent center gallery, where Carrara and Bardiglio marble flooring, marble-trimmed arches, classically sculptured busts, elaborate moldings, and a gold-leaf-adorned coffered Venetian plaster ceiling set an unforgettable tone. At the far end, a striking nook framing a south-facing window creates an idyllic spot for a writing desk and a daily connection to the historic surroundings. Multiple sets of double doors open to the separate wings, including two pairs that lead to the breathtaking, sunlit main living space. Here, soaring ceilings and Versailles-pattern oak flooring enhance an impressive open layout with abundant room for relaxing, formal dining, and entertaining on a grand scale. Ornate millwork, elegant chandeliers, picture molding, and a detailed fireplace mantel add to the room’s character, while oversized arched windows showcase lush treetops and views of the Second Bank of the United States. Sure to inspire plenty of home-cooked meals, the Joanne Hudson-designed chef’s kitchen is fitted with bespoke cabinetry, a paneled Sub-Zero refrigerator, a Wolf dual-fuel range, a Miele dishwasher, a distinctive tile backsplash, and a center island with a solid walnut top and seating. A pantry, powder room, and laundry cabinet are conveniently tucked just off the kitchen. Back through the center gallery, the bright, hotel-like primary suite boasts a sitting area, a walk-in closet, and a luxurious ensuite bathroom with dual vanities, a soaking tub, and a large glass-enclosed, multi-jet shower. Completing the home is a final wing with two additional bedrooms and a full hall bathroom. Residents of The Bank Building enjoy access the adjoining Renaissance Hotel, for possible valet parking. Outside the front door, the setting is just as special. Independence Mall and the historic streets of Old City surround the property, while sprawling Washington Square Park, top restaurants, friendly cafes, lively entertainment, and local shops are all steps away. Penn’s Landing and Center City are also close by, with easy access to I-95 and South Jersey. Rare in its combination of scale, craftsmanship, and setting, 421 Chestnut St #401 offers the chance to live among the landmarks that define Philadelphia in a residence every bit as memorable as the history outside its windows.
