[15] The complex's main structure is an elongated five-story building, stretching from Avenue John F Kennedy to Circuit de la Foire Internationale.

[2] The main structure has a gross area of approximately 180,000 m2 (1,900,000 sq ft), and consists of two parallel galleries either side of a central atrium spanned by a glass and polytetrafluoroethylene (PTFE) canopy roof.

[2] Attached to the main structure, along its northern edge, facing rue Carlo Hemmer, are four identical parallel five-storey wings used as office space.

[2] Between the two wings closest to Circuit de la Foire Internationale lies a later extension to the shopping mall's second storey, in the form of a single-storey food court, adding 2,400 m (7,900 ft) of floor space.

[2] Located between the complex and Circuit de la Foire Internationale is the Kubik building,[b] a cube-shaped structure, currently occupied by the European Stability Mechanism.

[2][21] However, the public entrances to the shopping mall are located to the east on Avenue John F. Kennedy, to the west on Circuit de la Foire Internationale, and to the north via the food court on rue Carlo Hemmer.
