The Barclay Condominium is a 22-story, 1930-era neo-Adam brick and limestone high-rise set directly on Rittenhouse Square in Center City Philadelphia. Originally designed by J.E.R. Carpenter and converted to condominiums in 1999, the building preserves prewar details—tall ceilings, crown moldings, herringbone and plank hardwood floors, and formal galleries—while offering modern mechanical upgrades and individually controlled HVAC. Residences are primarily large three- and four-bedroom floor plans that emphasize generous entertaining rooms, built-ins, butler’s pantries, substantial closet/storage space, and luxurious finishes such as marble baths and high-end chef kitchens with island workspaces. Common areas include a regal lobby with 24-hour doorman and concierge, on-site management, private fitness center, and access to a chauffeur-driven Mercedes S-Class; ground-floor retail features Stephen Starr’s Barclay Prime steakhouse. Exterior traits include street-level stone details, sidewalks and exterior lighting consistent with the historic streetscape. Services and conveniences also extend to valet/room service options and building storage. The property is pet-friendly and benefits from a premier Rittenhouse Square address with immediate access to upscale shopping, dining, cultural institutions, and regional transit connections.
