The south end of "Chaddy" was rebuilt in the late 1990s, as part of a "Stage 20" project. The original (circa-1960) Myer was demolished, with the new store -seen here- being dedicated in November 1998. It was joined by a David Jones department store 1 year later. These were linked by a curving, sunlit galleria concourse, completed in December 1999.

A "Stage 30" mall expansion, known as Chadstone Place, opened between late 2008 and early 2009. This "outdoor-style" addition consisted of 1 and 2-level structures, with a single-level parking deck covering a building on its east end. Chadstone Place housed several exterior-entranced stores, a "Fresh Food Precinct", al fresco dining area and 4-storey office tower.

A Woolworths supermarket, anchoring the new Chadstone Place addition, debuted in October 2008. The mega mall now featured 3 supermarkets; Woolworths, Aldi and the existing Coles. There was also a Colonial Fresh Markets fruit & produce store.

Above, we have a circa-2009 store map of the Ground Level (Upper Mall) of CHADSTONE CENTRE. By this time, the shopping precinct was being promoted as "The Fashion Capital".

In this image, we see a reconstructed West Mall section. Work got underway on this "Stage 33" project in May 2008. The 278 million dollar retrofit, which encompassed 463,000 square feet, was completed in November 2009.
