Argyle Flats is a three-story structure built on a raised basement. Its basic form is compact and rectilinear. It rises three floors above an exposed basement and features an asymmetrical facade. The smooth brick walls contrast with the rough textures of the cornices that feature Romanesque Revivalcorbelling and round-arched windows on the attic level in pointed gables that rise above the coping. Decorative details are found at the building's main entrances and on the cornice. The cornice itself continues across the deeply recessed hyphen between the two facades, which minimizes the reality that the building is two separate blocks. Argyle Flats also features full-height, polygonal, projecting window bays. There are two entrances in the main facade that each lead to flats on one side of a bearing or party wall. The exteriors of both sides of the building are a mirror-image of the other, which is typical of the city's double houses. An adjustment is made, however, as the north section of the building sets higher on the hillside than the southern section. Elements of the Victorian era are found in its picturesque facade.
