PARLY 2 was expanded with a South Wing in 1986-'87. The extension (in medium gray) incorporated eighty-seven stores and added 2,000 parking spaces; these provided in garages and decks situated below -and on top of- a new Y-shaped shopping concourse. The centre commercial now consisted of 3 floors -Niveaux 1, 2 and 3- and encompassed approximately 1,151,700 leasable square feet.

In this interior view, we see a section of the newly-expanded PARLY 2. Some of the stores that opened as part of the South Wing extension were Habitat (home furnishings), La Fruiterie, Compagnie du Californie (ladies' wear), Bayard (men's wear) and a branch of Great Britain's Marks & Spencer.
