Sleek Passyunk Square home with Ogee arches asks $550K

From the outside, this three-story rowhome at 1239 South 12th Street looks a lot like its neighbors—a square, three-story building with rooftop access.

But interior design elements give the 1,600-square-foot home unique character. That’s largely thanks to the heavy use of Ogee arches—arches that meet in a point above the entryway—throughout the home. That starts on the first floor, where the black-tiled arches connect a living room to a dining room and kitchen. Little cutouts in the dining room walls—featuring miniature versions of the same arches—look out over the living area.

The Ogee style continues upstairs, where it features in a bedroom alcove and in a shower (albeit this time with a pale pink and blue tile finish).

The home, built nearly a century ago in 1919, has four beds and two and a half baths.
