PARLY 2 was expanded in 1986-1987, with the 322,900 square foot "Sari-Progemo Wing" (indicated in medium gray). The extension incorporated 86 stores and added 2,000 parking spaces; these provided in garages and decks situated below -and on top of- the new Y-shaped mallway. With this addition, the "centre commercial" consisted of 3 floors; these designated as Levels 1, 2 and 3.


In this interior view, we see a section of the newly-expanded PARLY 2. Some of the stores that opened as part of the 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.
