20 S Letitia Street 5BPhiladelphia, PA 19106

Welcome to 20 S Letitia Street, Unit 5B – a one-of-a-kind penthouse residence at the prestigious Waterbridge Condominium in the heart of Old City. Designed by Harman Deutsch Architecture, this expansive 3-bedroom, 3 full bathroom, 2 half bathroom home spans two full floors and 3,600 square feet of refined living space, offering a rare blend of scale, luxury, and privacy. In addition to the two full floors, a dramatic third level leads to the private roof deck. A striking, custom-designed steel staircase—craned in as a single sculptural piece—gracefully connects all levels of the home, creating a dramatic vertical flow from the main living spaces to the private rooftop retreat.
Upon entry, custom stone walls in the foyer and living room immediately establish an atmosphere of architectural elegance and warmth. The dramatic living area is enhanced by soaring ceilings and oversized windows that flood the space with natural light. A stunning 72-inch gas fireplace serves as a striking focal point, while wide-plank hardwood floors flow seamlessly throughout the home, adding richness and continuity to every room.
The gourmet kitchen is a chef’s dream, equipped with commercial-grade KitchenAid appliances, stone countertops, a large island, and extensive 42-inch custom cabinetry. A thoughtfully designed wet bar with a mini fridge, wine fridge, and dishwasher elevates the entertaining experience. Custom closets throughout the residence ensure ample and stylish storage.
Each of the spa-like bathrooms showcases refined marble finishes, with the master bathroom featuring heated marble floors for a touch of everyday indulgence. The primary suite is a luxurious retreat with generous proportions, a lavish ensuite bath, custom closet build-outs, and direct access to a private terrace.
The third floor offers direct access to a massive private rooftop deck with sweeping 360-degree views of the river, bridge, and city skyline — a true rarity in the neighborhood. A media room, smart home technology, and a curated selection of high-end finishes throughout complete this exceptional home.
As an added bonus, the seller is offering one year of pre-paid parking at the Strawberry Street Garage, located just steps away on Letitia Street, making city living even more effortless. A tax abatement is in place through 2029, providing significant savings for years to come.
