1901 Walnut St

Rittenhouse Plaza is a pre‑war, New York–style cooperative completed in 1925 and set directly on Philadelphia’s Rittenhouse Square. The masonry building rises multiple stories with a formal marble lobby, double‑barrel vaulted ceilings and a doorman/concierge station providing 24‑hour staffing. Residences range from one‑bedroom pied‑a‑terres to large multi‑bedroom apartments and expansive penthouses, many retaining original period details such as inlaid mahogany and oak hardwood floors, crown moldings, wainscoting, curved beam and coffered ceilings, and traditional center‑hall plans. Unit interiors combine historic character with modern updates: eat‑in and gourmet kitchens with high‑end appliances in many homes, multiple bathroom styles including soaking and jetted tubs or steam showers, abundant built‑ins, walk‑in closets and in‑unit laundry in select units. Shared amenities emphasize service and urban convenience — a landscaped private courtyard garden, community room, on‑site staff, private storage/lockers, and exterior lighting with sidewalks and street lighting. The co‑op structure includes comprehensive monthly fees that commonly cover taxes, utilities (heat, water, sewer) and building internet/cable; a one‑time co‑op transfer fee and application charges apply. The building is pet‑friendly and offers nearby rentable parking rather than structured resident garages. Located steps from Rittenhouse Square, the property places residents within immediate access to restaurants, boutiques, cultural institutions and public transit, delivering a central Center City lifestyle rooted in pre‑war architecture and attentive staffing.
