    There are penthouses... and then there is The Penthouse. An exceedingly rare and truly once-in-a-lifetime opportunity awaits in Waterfront Square, Philadelphia's premier gated waterfront community.

Adding to its unmatched appeal is more than 2,000 square feet of private terrace space - an extraordinary outdoor retreat perfect for elegant entertaining, intimate gatherings, or simply enjoying sunrise over the river and the dazzling city lights each evening. Recently refreshed throughout, the residence showcases fresh designer paint, new luxury vinyl plank flooring, and a beautifully renovated main gourmet kitchen appointed with contemporary finishes and abundant workspace. A second full kitchen on the upper level creates exceptional flexibility, making the upper floor ideal as a private guest residence, multi-generational living space, executive retreat, or the ultimate entertaining level. Whether hosting grand-scale events or enjoying the serenity of luxury waterfront living, this remarkable penthouse delivers an experience unlike anything else in Philadelphia. Residents of Waterfront Square enjoy an exceptional collection of resort-style amenities including 24-hour gated security, concierge service, valet parking, state-of-the-art fitness facilities, indoor lap pool, spa, riverfront walking paths, beautifully landscaped grounds, and convenient shuttle service to Center City. Just minutes from Philadelphia's finest restaurants, cultural institutions, sporting venues, and major highways, this is luxury living without equal. A residence of this caliber is rarely offered and impossible to replicate. This is more than a home-it is one of Philadelphia's most extraordinary addresses.
