Alpha Alternative (formerly Brant Street Public School) is architecturally significant as a good example of Neo Gothic design favoured for early 20th century educational buildings. Contextually, the building is a local landmark as one of the few institutional buildings found in the King-Spadina neighbourhood. The heritage attributes of the building are found on the exterior walls and roof. Rising three stories above a basement, the structure is built of reinforced concrete blocks clad with brown brick and trimmed with stone. On the six-bay principal (east) facade, the main entrance is located at street level in the right (north) bay. A round-arched stone portal with a multi-paned transom is decorated with an oversized hood mould, carved spandrels, a name plaque, and a date stone. Narrow rectangular openings are paired in the basement level beneath a thick stone band course. The horizontal emphasis is continued in the first floor where a continuous stone sill connects the large flat-headed window openings. Above a stone cornice, the upper two stories are divided vertically by a sequence of thick and thin brick piers with stone coping. The piers separate narrow flat-headed window openings and create a varied silhouette at the flat roof. The finishing cornice is decorated with stone rondelles and shield motifs. The remaining elevations continue the horizontal divisions introduced on the east facade. The pattern of openings is repeated on the west wall, while the north and south elevations feature central frontispieces and minimal fenestration. A secondary entrance is located on the south wall.
