A circa-2009 physical layout of Arizona's Diamond in the Desert. The mega mall dedicated its tenth enlargement in October 2009. A vacant anchor on the east end was bulldozed and replaced with a Barney's New York, 2 levels of underground parking, and a shopping concourse extension. At this time, the mall's retail level orientation is as follows; Palm Court Floor, First Floor and Second Floor.  


The Barney's New York "luxury department store" at SCOTTSDALE FASHION SQUARE was short-lived. It was dedicated in October 2009 and shuttered in May 2016.

In a near-constant state of renovation, SCOTTSDALE FASHION SQUARE dedicated a North East Expansion in December 2015. This project added a state-of-the-art multiplex and Dick's Sporting Goods retail store.

Soon after construction dust settled, work was underway on -yet- another mall expansion. An Elevated Luxury Wing was built on the northwest corner. Its first phase brought two levels of trendy retail and restaurants; all surrounding a grand entrance. The first stores opened in November 2018.
