The History of Williams Island: How The Trump Group Built South Florida's Florida Riviera

Williams Island doesn't owe its existence to grand real estate ambition. It owes it to rock mining.

The 84-acre peninsula that juts into the waters between Dumbfoundling Bay, Maule Lake, and Little Maule Lake was not shaped by the sea or the wind. It was shaped by industry. Evert Price Maule, founder of Maule Industries and father-in-law of Raymond Gaylord Williams, ran a rock quarrying and aggregate operation in the Ojus area of what is now Aventura. Decades of extraction work inadvertently sculpted the landform that would eventually carry his son-in-law's name.

The Williams Family

Raymond Gaylord Williams arrived in Miami in 1924, or rather, his father did. Raymond's father had been recruited by George E. Merrick, the visionary developer behind Coral Gables, to establish a military academy in the newly platted city. The family put down deep roots in South Florida, and the Williams name became attached to the land that Maule's quarrying had quietly formed.

In 1969, Raymond Gaylord Williams sold the Williams Island tract to Saul J. Morgan and Norman Cohen for $1,815,000. The land, covered in Australian pines and framed by still water, sat quietly on Aventura's edge, undeveloped, unnoticed, and waiting.

The Trump Group Acquires the Land

In 1980, Norman Cohen sold the property to Julius (Jules) and Edmond (Eddie) Trump for $17,616,500. The Trump brothers were South African-born Jewish brothers who had immigrated to the United States in the 1970s. They were entirely unrelated to Donald Trump or the Trump Organization, a distinction that would eventually require litigation to formally establish in the marketplace.

What Jules and Eddie Trump shared was a talent for identifying undervalued real estate. They founded The Trump Group and built it into one of South Florida's most respected luxury development firms. In the Williams Island peninsula, they saw something extraordinary: a natural moat, a waterfront setting on the Intracoastal Waterway, and complete isolation from the mainland, achievable simply by constructing a gatehouse and a series of entrance canals.

Breaking Ground: The Florida Riviera

Partnering with the Mutual Benefit Life Insurance Company, The Trump Group broke ground in the early 1980s with a Mediterranean vision: terracotta rooflines, arched loggias, cascading bougainvillea, and a continuous water surround achieved by digging canals along the peninsula's entrance. They named it "The Florida Riviera", and the name stuck.

The first building, 4000 Island Blvd, opened in 1985 as the island's inaugural high-rise. It was followed by 3000 Island Blvd (1989), Mediterranean Village at 3500–3900 Island Blvd (1989), and then 2800 and 1000 Island Blvd (both 1991). Mediterranean Village, three low-rise buildings with barrel-tile roofs, arched entryways, and private courtyard patios, helped define the Florida Riviera aesthetic that would become the community's visual signature.

The 1990s: The Community Fills Out

The 1990s saw Williams Island develop its full identity as a residential campus. Villa Fiora (36 private villas with direct garage access) was completed in 1993. 2000 Island Blvd followed in 1996. Then came the pairing of 2600 Résidence du Cap (1997), exclusively large-format residences starting at 2,450 sq ft, and 7000 Villa Marina (1998), the island's most prestigious address and the only tower with simultaneous Bay, Intracoastal, and ocean views.

What surprised observers was how well Williams Island sold during periods of broader market weakness. Latin American and European buyers, attracted by the community's genuine island seclusion and resort-style club, drove demand throughout the 1980s and 1990s even when the broader South Florida condo market softened.

Bella Mare: A New Standard (2005)

6000 Bella Mare, completed in 2005 by WCI Communities, brought the most comprehensive amenity package the island had seen, a poolside bar, sauna, business center, and billiards room alongside a heated pool and spa, fitness center, tennis courts, and private marina access. Alongside Villa Marina, Bella Mare remains one of only two towers with Bay, Intracoastal, and ocean views. Its completion marked the end of the Trump Group era and the beginning of a new chapter.

Bellini: The Final Tower (2013)

The final high-rise tower, Bellini at 4100 Island Blvd, was completed in 2013 by developer Martin Margulies, known in South Florida not only as a real estate developer but as one of Miami's most significant art collectors. Boutique by design, just 68 residences across 24 floors, Bellini introduced private elevator access to each residence, 10-foot ceilings (12 feet in penthouses), and wraparound glass balconies. It is the island's most contemporary building and, by most measures, its most exclusive.

Williams Island Today

Today Williams Island encompasses 84 acres, 13 residential buildings, and over 4,200 residences. The Williams Island Club serves as the social heart of the community. The Island Pool & Restaurant provides resort-style outdoor facilities, and the private marina accommodates vessels up to 100 feet. The island remains the only private island community in Aventura, and one of the most distinctive luxury addresses in all of South Florida.

The Florida Riviera lives on.
