The early 2000s remodeling -and Great Recession- bankrupted the owner of HILLDALE CENTER. By 2010, the complex was in foreclosure. A New England company bought the mall in 2012 and were soon busy with a first phase demalling project. Between 2014 and 2015, the North Wing was partially demolished and rebuilt in an open-air format.

The new North Wing -officially known as The Plaza- is shown in light gray on this circa-2015 layout. It brought several tony stores into the fold, such as Sur La Table, Michael Kors, White House / Black Market and Lucky Brand. The enclosed South Wing would remain as is...at least for the time being.
