The Mrs. Martha J. Bowles House is a one-story, hip-roofed Colonial Revival-style house with an impressive engaged front porch. The porch is supported by large, square, fluted columns and pilasters with simple square caps and has a tall, weatherboarded porch span and replacement rail. The house and porch have a painted brick foundation and an asphalt-shingled roof. The house has original wood weatherboards and a corbelled, interior brick chimney. Black shutters flank the two-over-two wood windows on the front elevation. The front door is a modern replacement. The roof has exposed rafter tails and a hip-roofed dormer has been removed from the house. There is a shallow bump-out on the left side of the house with a hipped roof, following the slope of the main roof. A shed-roofed addition and an enclosed shed-roofed porch are visible at the rear of the house. A stuccoed brick retaining wall runs along the street with a brick stair with stuccoed kneewalls providing access to the house.
Mrs. Bowles was the widow of John W. Bowles and is recorded as living on this block of Mallard Avenue (then Markham) in 1919. In 1915, she lived at 1010 Burch Avenue.
