Turchi’s high-rise proposal is the latest attempt by the developer to get a project at the Dilworth House off the ground — and, if he is successful, would add more pricey units to Philadelphia’s growing luxury real estate market. One of Turchi’s lawyers, Philip Rosenzweig, of Silverang, Donohoe, Rosenzweig & Haltzman LLC in St. Davids, said that the project would “obviously be very high-end” and would feature an automated valet parking system underground that could accommodate 20 spaces, zoning documents show. The tower, which would rise behind the front portion of the Dilworth House, would include a roof deck, balconies, and amenity spaces, according to the documents.
