Plans for a PLAZA renovation had been on the drawing board for years. Remodelings were announced -and postponed- in 2009 and 2014. As part of the refurbishment proposed in 2014, the roof of the complex was to be torn off and stores reoriented with an upscale "beach" motif.

Westfield sold "Carlsbad Mall" in November 2015, after repurposing a vacant Robinsons-May as a cinema, fitness center and restaurant streetscape. Rouse Properties, the new owner, renamed the mall SHOPPES AT CARLSBAD (its fifth name since 1969). They proceeded with the renovation started by Westfield. In this circa-2017 plan, we see the new Dave & Buster's that has opened in the lower floor of the old Robinsons-May.

The roof-removing renovation proposed by Westfield in 2014 was amended by Rouse Properties. They decided to maintain SHOPPES AT CARLSBAD as an enclosed mall, giving its interior and exterior a major makeover. The remodeling was complete by late 2018.
