Aventura is not the only mall that is bucking trends. Other large, luxury-focused properties seem to be weathering the retail apocalypse equally well. One is Mall of America in Bloomington, Minn., the largest mall in the United States at 3.1 million square feet. Others are South Coast Plaza in Costa Mesa, Calif.; the King of Prussia Mall near Philadelphia; and Fashion Show in Las Vegas, which all have healthy vacancy rates of less than 3 percent, said Kevin Cody, a senior consultant at CoStar, which provides analytics on commercial real estate.

At Westfield Century City in Los Angeles, customer visits rose 93 percent from 2017 to 2018 after a $1 billion renovation, according to Placer.ai, a company that analyzes foot traffic using cellphone data.

Anchored by department stores like Nordstrom, Bloomingdale’s and J.C. Penney, and featuring the long halls lined with smaller stores that have characterized mall design since the 1950s, Aventura in some ways seems to be a typical shopping destination.

But the property has not been shy about investing in its infrastructure, and has grown by about 50 percent in size since 1983. Today, it offers 2.5 million square feet of stores, making it the ninth-largest enclosed mall in the country, according to CoStar.

Aventura’s third expansion, a $214 million undertaking completed in 2017, added an airy 315,000-square-foot wing illuminated by a 347-foot-long skylight.

That an old mall could offer newly built storefronts was appealing, said Kenny Minzberg, a vice president of Psycho Bunny, a clothing company that had been selling mostly online before choosing Aventura for its first physical store. The 1,600-square-foot outpost, which opened in 2018, is near stores for Warby Parker and Casper Mattress, other retailers that began life on the internet.

The expansion also made over an existing food court, giving an upscale polish to a mall staple. Now called Treats Food Hall, the eatery sells lobster rolls, Cuban food and pizza. Nearby is a ceviche restaurant, a barbecue joint, and Tap 42 Craft Kitchen and Bar, which, in an un-mall-like arrangement, has outdoor seating and serves drinks past midnight. Two hair salons, two nail salons and a Tesla dealership are also in the mix.
