Between 1908 and 1914 the Dunlop house was greatly altered in style when the second owners made two major additions. The living room, dining room and master bedroom were greatly enlarged, glass enclosed sunrooms were added, and elaborate interiors were created. The architect of the remodelling is not definitively known, but is thought to perhaps be Charles White, Jr. The house is now in a "complex rectilinear" style characterized by flat surfaces, a gabled roof, rectilinear masses and patterned windows, a style common in Oak Park between 1900 and 1915. In this example there are also decorative wood strips under the eaves. The gable with the Palladian window is all that remains of the original front façade.
