The American Hat Frame Building is architecturally significant as a well-designed example of the tall commercial building type that is distinguished by its geometrical ornamentation. Located on the east side of Bathurst Street between Front and King Streets, the building contributes contextually to the character of the King-Spadina neighbourhood as it developed as an industrial area in the early 20th century. The heritage attributes of the building are found on the exterior walls and roof with attention focused on the principal (west) façade and north wall on Bathurst Street. Rising four stories above a basement, the steel-frame and brick structure is clad with red brick and trimmed with stone and contrasting brick. The three-bay principal (west) facade features a Classical organization of base, shaft and attic with stone string courses dividing the parts. The main entrance, located at street level in the right (south) bay, is recessed in a simple channelled stone surround that extends to the height of the first-floor openings. The commercial windows introduced in the basement are repeated in the shaft, where they display recessed brick panels. The openings are divided vertically by yellow brickwork in the form of decorative piers connected at top and bottom by geometrical motifs. The ornament is continued in the attic level above and between the segmental-headed window openings. The regular pattern of fenestration and the decoration are repeated on the north elevation along Wellington Street West, while the south wall has segmental-headed openings.
