It takes something more audacious to sell beachfront property these days to the global ultra-wealthy who arrive in Miami with millions to spend on second or third homes. It takes words invested with meaning in the language of the international jet set: Porsche. Giorgio Armani. Fendi.

With a slew of residential and hotel developments, Miami is embracing the notion that homes, like cars, handbags and jewelry, should carry luxury designer labels. The trend has spread from Europe, Asia and the Middle East, where developers discovered that luxury-branded hotels and homes could command huge premiums that the moneyed set would happily pay.

Having transformed New York and London, the wealthy are increasingly pursuing new havens. Miami is luring Argentinians, Brazilians, Chinese, Russians and French. The purchases go beyond the appeal of haute logos: Owning an asset priced in dollars can protect fortunes from the shrunken values of euros, pesos and rubles.

The pull is so powerful that developer Gil Dezer’s Porsche Design Tower is mostly sold out, even though construction won’t wrap until early 2016.

Shaped like a piston driven into sand, the concrete-and-glass Porsche Design Tower will contain three car elevators. Each can whisk a convertible up 60 stories and then slide it into the owner’s personal steel-reinforced garage. (The owner can stay in the driver’s seat.) Inside the apartments, curved windows capture a vista of waves billowing from a midnight blue into a pale green along the shore.

For the designers and builders, the partnership offers dual rewards: The brands gain a revenue stream and enhance their cache. The developers and owners benefit from the allure of a treasured name and logo.

“What we’re selling is luxury,” Dezer said. “The buyers already know the brand. They like the style, they like the look and that’s why they feel more comfortable buying it.”

Dezer is also taking reservations for condos at the Armani Casa. The Chateau Group is building the Fendi Chateau steps from Chanel, Gucci and Tiffany boutiques. Nearby is the Faena District, a condo, hotel and cultural center backed by Argentinian hotelier and fashion designer Alan Faena.

Their emergence has spawned thousands of skilled construction jobs. Yet it’s also produced an epic surge in home prices. And it’s walled off Miami’s coastline behind a phalanx of skyscrapers that has isolated low- and middle-income residents. Many have had to buy farther and farther inland, said Aaron Drucker, a managing agent for Redfin, the real estate brokerage.

“Locals are not really part of the party,” Drucker said. “It’s a little bittersweet for folks who aren’t going to be able to enjoy the beauty of Miami.”

Demand from European and South American buyers caused prices for the top 5 percent of homes around Miami Beach to surge 66 percent in the past year to US$6.3 million, according to Redfin. That compares with a 5 percent increase in luxury prices nationwide. Miami Beach’s gains dwarfed price increases of top-tier homes in San Francisco, Los Angeles and Washington DC.

Global buyers are largely paying with cash. Some may be shifting their holdings from US bank accounts after the IRS sought to reduce tax avoidance in 2012 by requiring banks to report interest earned on accounts held by foreigners. Those accounts are estimated to hold up to US$400 billion, according to court filings.

Two-thirds of sales in the Miami area were all-cash, compared with 48 percent in other US markets with high proportions of international buyers, Redfin found. Nationwide, by contrast, all-cash sales accounted for only about a quarter of purchases in February, according to the National Association of Realtors.

A result is that the demand for branded condos is far outpacing the fundamentals of a Miami-area economy that’s still recovering from the housing bust. Over the past year, average hourly wages in metro Miami have risen just 1.3 percent to US$22.74 an hour, according to the Labor Department, below national averages.

“The typical metrics used to measure real estate markets — such as local job growth — don’t apply here,” said Neisin Kasdin, a former Miami Beach mayor and lawyer who represents developers of the Faena District. “I’ve never seen this congregation of wealth before.”

Branded homes are helping attract buyers unfamiliar with Miami’s luxury housing, said Liam Bailey, global head of research at the London-based real estate consultancy Knight Frank.

“There is a marketing benefit of having a brand that is recognized outside the market,” Bailey said. “There is an element of trust.”

The developers enjoy a growing pool of wealth to target. Roughly 173,000 individuals worldwide are worth more than US$30 million, a population that rose 3 percent last year, according to a report by Knight-Frank. Their numbers are forecast to swell an additional 34 percent over the next decade, meaning that more foreign buyers will be looking for homes in New York, Los Angeles, Miami and elsewhere.

In setting up the Porsche Design Tower, Dezer identified and sent packages to 1,500 individuals with an affinity for the German automaker. The outreach produced 62 sales.

More than 90 percent of the 132 condo units have been sold. Prices started at US$4 million, with penthouses listed for above US$30 million. The buyers are committing millions to a designer condo based on blueprints, models and animated videos. They agree to pay 50 percent of the purchase price in installments during construction.

Just the idea of the car elevator was enough to persuade Juan Pablo Verdiquio to buy at the Porsche Design Tower.

“I took a leap of faith,” said Verdiquio, who had moved to Miami from Argentina a few years earlier and launched a construction business.

In the end, he decided the condo he had bought for vacations was lacking as a year-round family home. For Verdiquio, who drives a Porsche 911 4S, the tower seemed a perfect fit. So he bought an apartment.

But then Dezer also showed him the blueprints for the Armani building, whose architect, Argentine Cesar Pelli, known for designing the Petronas Towers in Malaysia, Verdiquio admired. The prices, starting at US$1.5 million, were less extravagant. So Verdiquio bought a unit there, too.

He expects the designer labels to carry weight from Shanghai to Sao Paulo, giving his apartments more value than one with an ordinary name chosen by a developer.

“I think it’s going to be a huge landmark for Miami and, I think, worldwide,” Verdiquio said.

Yet Dezer also pitches Miami as a bargain compared with other global cities. The average Miami Beach condo sells for US$760 a square foot, according to brokerage Christie’s International. That makes it cheaper than a comparable pad in Monaco, New York City, London, Moscow, Paris and Beijing.

With only so much oceanfront, the condos should become a scarce resource that appreciates over time, Dezer said. “People look at these apartments as bank accounts,” Dezer said.
