Montreal Planetarium

The relocation of Montreal’s planetarium to the heart of the Olympic park represents a substantial design challenge, notably in relation to the urban planning of the site as well as architectural anchoring of a new building within a site which is central to Montreal’s identity. Hence, an innovative proposal had to be set forth, which had its own distinct identity while embedding itself within its surroundings.

Therefore, in order to make the entrance from Pierre-de-Coubertin more dynamic and maintain pedestrian interest throughout the site, a sinuous path was designed. Textures, water basins, landscaped and rest areas succeed one another and offer life to the existing concrete path. Reinforcing the Olympic park’s buildings by following their forms, the path claims that movement around the park also holds importance.

The planetarium’s envelope recalls the fluid curves distinct of its neighbors. Its abundant glazing allows dialogue with the biodome’s curtain wall, as well as a strong indoor/outdoor connection, which not only allow to reduce the impact of the building’s mass, but also place emphasis on the central sphere. The literal and metaphorical heart of the project, the sphere can hence be seen no matter the person’s point of view. The transparency also helps make this gesture appear light, even given the planetarium’s substantial dimensions.

Permanent and public exhibitions flow across three storeys, orbiting around the sphere in a space free of obstacles. Additionally, this creates a free-flowing building which presents countless occupation opportunities. A 3-meter setback between the exterior façade and the floor plate creates a more monumental feel as well as allowing for visual links to be created between storeys. The second storey marks the focal point of the visit, as it is home to the theaters. The last storey hosts a private terrace rooftop, designed with a special attention given to its relation to the public grassed area.
