The station was constructed as an anti-directional cross-platform interchange, with three lateral tunnels containing two storeys each, joined by four cross-tunnels; both lines therefore have stacked platforms.

The station's main artwork, a group of four murals by Claude Guité running the full length of the platform and entitled Les quatre saisons (the four seasons).

The murals are painted on 500 panels of asbestos cement stretching the entire length of the platforms, they portray semi-abstract scenes of the foliage and weather associated with each of the four seasons.

As of June 2010 all the murals have been repainted, and are partially reinstalled on all four platforms of the station with a protective sheet of glass to prevent any future vandalism.

The underground station platforms, located under Avenue Dornal, are approximately four blocks—about 250 m (270 yards)—east of the site of Snowdon Junction, a major transfer point during the streetcar era.
