The two-story building, at 150 N.E. Eighth St., Miami, will total 78,000 square feet and include a rooftop overlooking World Square plaza, a public gathering space at the end of a retail-lined pedestrian paseo. It’s being developed by Miami-based Miami Worldcenter Associates and Los Angeles-based CIM Group.

Designed by Coral Gables-based Nichols Brosch Wurst Wolfe & Associates, the jewel box will have floor-to-ceiling glass.

“The final elements of this world-class retail development plan are coming together, and the design and concept for the signature ‘Jewel Box’ element reflects the strong feedback we’ve received from brands from around the world and across South Florida,” said Nitin Motwani, managing partner of Miami Worldcenter Associates. “Traditional retailers, food and beverage, and entertainment concepts see value in having a presence in a well-located, well-connected site combining residential, hotel, office and retail uses within a single master-planned development.”

“Bringing the right mix of boutique retail, eclectic dining, and diverse entertainment options to Miami Worldcenter is key to creating a vibrant destination that is attractive to Miami locals and visitors,” said Shaul Kuba, co-founder and principal of CIM Group.
