118 S 21St St

Located at the corner of 21st and Walnut in Philadelphia’s Rittenhouse Square, this midcentury cooperative rises 14 stories and was completed in 1954. The property primarily offers one-bedroom floorplans, with occasional two-bedroom units and varied layouts spanning efficient studios to generously proportioned corner homes. Interiors commonly feature period details updated over time — hardwood floors, crown moldings, recessed lighting, open floor plans, eat-in or gourmet kitchens, walk-in closets, and renovated bathrooms that range from soaking tubs to glass-enclosed walk-in showers. Building circulation is served by elevators and a staffed 24-hour front desk with on-site management and maintenance handling daily operations. Shared spaces are extensive for an urban cooperative: a landscaped rooftop terrace and sun deck with city views, laundry facilities, a library, bike rooms, guest suite accommodations, and indoor amenities for storage and community use. Exterior features include awnings, exterior lighting, sidewalks and a roof deck; many units look over a central garage courtyard. Parking is available via an on-site valet garage for an additional fee. The co-op’s governance carries purchase restrictions and underwriting requirements—sales are typically cash-only or require cooperative approval, and pets such as two cats, a caged bird, and fish are commonly permitted. Positioned in a premier, walkable neighborhood, the building places restaurants, high-end retail, parks, transit links, and cultural destinations within immediate reach. Monthly carrying fees are noted to include most utilities, taxes, and basic cable, consolidating running costs under the co-op dues and reflecting a full-service urban residential model.
