A side deck off the kitchen is perfect for morning coffee or al fresco dining. Additional features include wood floors, recessed lighting, original wood banisters, excellent closet space, and a second-floor ensuite bath, plus an additional 2nd-floor bathroom. There is also potential for a future roof deck off the third floor. The home also offers dual-zoned heat and central air, two high-efficiency heaters, and a high-efficiency water heater. There are three electric meters, two panels, and one gas and one water meter. The rear garage is currently used for storage. There is also a person-sized door to the yard and an electronic overhead door that provides vehicle access to the lots, offering the opportunity to build new homes or create a private outdoor oasis with off-street parking. The location is just 3 blocks from Dickinson Square Park and about a half mile to the shops and restaurants of Passyunk Ave. It offers convenient access to I-95, I-676, and Columbus Blvd retail.
