270 Montrose Avenue is a 2 1/2 story, 7 bay, rectangular plan, brick, Tudor Revival, residential building. The c. 1920, slate-clad, side gable-roofed house is articulated by two major cross gables, an attached garage, and projecting mortar joints in the brickwork. Fenestration consists of round-arched windows and doors on the first floor, and leaded casement windows on the second floor. Simple, classicizing window surrounds match the entablature.
