Just listed in one of Rittenhouse Square's most prestigious, elegant boutique buildings! All the elements needed to create a designer city residence are here: high ceilings, generous square footage (3,217SF), views of the Square and cityscape, and a structure that permits an open floor plan. There presently is a living room, dining room, kitchen, four bedrooms and 4.1 baths. As a bonus, the windows were recently replaced in the building. For buyers seeking privacy, there are only two apartments per floor and an underground parking garage where owners have an assigned space and may come and go as they please. Bring your architect/designer and see for yourself the potential this apartment holds given its square footage and premier address in directly on the Square.
