Along 37th Street, the water table containing the raised basement is topped by a molding. The original 1853 house to the west and the 1888 extension to the east are divided by a pier about halfway through the length of the facade, which spans the first through third stories. The original section of the house is three bays wide and contains window articulation similar to that of the Madison Avenue facade. On the first floor, the second opening from west has a balcony with an iron balustrade and a pediment supported by Corinthian columns. On the original second floor, the second bay from west is flanked by oval windows on either side, while the third bay from west is an oriel window. Within the 1888 extension, the first floor contains a projecting three-sided bay supported by pilasters and flanked by carved panels, as well as a blind arch opening to the east. The second floor of the extension contains paired window openings flanking a smaller triple window, while the third floor contains paired windows on either side of an oval window. The cornice above the third floor, as well as the attic, in both the original house and its extension is similar to that on Madison Avenue.
