As a result of commercial competition, the IGUATEMI mall was expanded and refurbished. Additions from the late 1970s are shown in dark gray on this circa-1983 site plan. The latest enlargement, in lighter gray, has just added a second multilevel parking facility and new northeast facade. The existing structure has also been air-conditioned, with the entire complex being renamed IGUATEMI SAO PAULO.

A view of Garage Nova (or the "New Garage"). Completed in 1982, it extended the northeast facade of IGUATEMI SAO PAULO out to the curb of the "Faria Lima" throroughfare. A third level of retail was also added to the circa-1966 building.
