306 Warwick Avenue is a 2 1/2 story, 3 bay, “L”-shaped plan, vernacular, wood frame, residential building. Built c. 1875, the synthetic siding-clad house has an intersecting gable roof, semi-hexagonal bays, 2/2 windows, cornice returns and a Doric column-supported pedimented portico. One of the original homes of the Montrose area, this house was owned by Paul Fuller at the turn-of-the-century, and later by Harry J. Schnell (1911). Although the house has been altered with the application of aluminum siding, it has retained enough integrity to be considered contributing.
