As of 2008, it is the second-tallest in the city, behind the nearby 1000 de La Gauchetiere, which was completed the same year (1992). Despite being 6 m shorter than 1000 de La Gauchetiere, it is built on higher ground and thus also reaches the maximum allowed elevation from sea level (that of Mount Royal). The design is partly dictated by the building's position at the western edge of the downtown core, with its shape forming a boundary between the commercial center and the residential periphery. As such it has a markedly rectangular footprint, being very elongated on a north-south axis. Emphasis is given to the east and west facades, which have opposed yet complementary appearances that strongly relate to the urban area they face. The modern-style western facade, facing the residential periphery, is a straight granite-clad wall covered with square windows, with irregular setbacks creating the appearance of several superimposed slabs. Conversely the postmodern-style eastern facade, facing the commercial center, is dominated by an outwardly-curved glass curtain wall that extends past the southern edge, creating a suspended vertical 'fin' that emphasizes the structure's impression of lightness and thrust.
