English: Built in 1870, this Second Empire-style mansion was renovated by Edward B. Green to house the Buffalo Club in 1889 and 1908, modifying it with multiple additions to the sides and rear. Prior to becoming the Buffalo Club, the house was the residence of Stephen V. R. Watson and his family, whom owned a grain elevator and a lot of real estate, and helped found the Buffalo Street Railway, Erie County Savings Bank, and the Buffalo Public Library, as well as being a representative to the state assembly in the 1860s. The house originally featured a third floor ballroom and theater, which could accommodate 300 guests, foreshadowing its later use as the Buffalo Club. The house was sold to the widow of Samuel L. Pratt in 1880, upon Watson’s death, with Mary Jane Pratt living in the house until 1887, when she sold it to the Buffalo Club, which subsequently renovated it. The building features a mansard roof with a cornice and gabled dormers with arched upper sash, red brick exterior, one-story bay windows with cornices and pilasters on the east facade flanking the main entrance, a stone base, stone lintels and sills, a decorative stone surround at the main entrance with an arched window over the entry door, doric pilasters, and a cornice, and an enclosed sun porch with large windows, a cornice, and brick columns on the south facade. The additions predominately feature red brick exteriors, low-slope roofs, and stone trim, with an addition immediately behind the north end of the original house featuring a two-story mansard roof, and a large neotraditional wing at the west end of the complex, at the rear of several earlier additions onto the original house. The building is a contributing structure in the Allentown Historic District, listed on the National Register of Historic Places in 1980.
