The architectural design of the Oliver D. Fit ley house, just north of 68th Street on the west side of Park Avenue, is in every way compatible with the former Percy R. Pyne house it adjoins. The first floor rusticated base, the limestone belt course at the fourth floor window sill level, as well as the stone cornice and balustrade carry through similar designs at the same level, and the color and pattern of the brickwork are identical. This is entirely by intention since the same architects, McKim, Mead & White, designed both houses. Oliver D. Filley was Percy Pyne’s son-in-law, and there was formerly a physical interior connection between the two houses.
