2135 Walnut St

Walnut Plaza is an early-20th-century residential condominium in Rittenhouse Square, Philadelphia, originally constructed in 1900 and converted to condo ownership. The midrise building contains primarily one- and two-bedroom residences arranged around an open-plan layout with features commonly updated in individual units such as hardwood floors, renovated kitchens with granite or quartz counters, and primary baths. Architecturally it presents a traditional urban façade and bay-style windows in many units that provide southerly and westerly light and skyline views. Common building services focus on practical upkeep: onsite management, exterior and common-area maintenance, snow removal, trash removal, and insurance are included in the condo fee; laundry facilities are located in the common basement. Exterior conditions are pedestrian-oriented with sidewalks and immediate access to Rittenhouse Square, transit, and nearby institutions (UPenn, Drexel, CHOP). Pet-friendly policies and garage-adjacent street parking patterns accommodate city dwellers. The overall character is walkable, community-minded condominium living that blends period building bones with individually modernized interior finishes and a low-amenity, maintenance-included ownership model.
