Death of Robert Eustace, Jensen Beach FL – Visionary Entrepreneur and Owner of Hutchinson Island Mansion Dies on November 20, 2025
The Jensen Beach community is mourning the loss of Robert Eustace, the esteemed Florida resident and owner of the iconic Hutchinson Island mansion, who died on November 20, 2025. His passing leaves a profound void in Martin County, where he and his wife, Elsa, built one of the region’s most admired private estates and shaped a legacy defined by innovation, philanthropy, and community impact.
Located at 4545 NE Ocean Boulevard, the Hutchinson Island mansion has long been one of Florida’s most recognizable homes. Visitors traveling along SR-A1A often paused to admire the stunning architecture and expansive coastal presence of the 50,000-square-foot estate. Built on more than 4.5 acres along the Atlantic Ocean, the property reflects Robert Eustace’s commitment to excellence and his passion for ambitious design.
The mansion includes a 21,000-square-foot main residence and an 11,500-square-foot guest house, supported by two security gates, two swimming pools, and private beachfront access. Its engineering capabilities remain unmatched in the region, with construction designed to withstand 200-mile-per-hour hurricane winds. Forty-two gothic columns, 11 domes, 11 rotundas, and 10 high arched windows give the residence its signature architectural identity. The home is considered one of the most remarkable private properties on Hutchinson Island and became a widely recognized Treasure Coast landmark.
Each holiday season, the estate came alive with a Christmas lights display that drew thousands of visitors. From early December through the first week of January, the Eustace residence illuminated the coastline with hundreds of thousands of synchronized lights. The tradition evolved into one of Hutchinson Island’s most anticipated annual attractions. Families, travelers, and local residents visited the mansion to experience the vibrant show that transformed the property into a festive spectacle of color and movement.
Robert and Elsa used the beloved holiday display to support charitable initiatives throughout Florida. Their philanthropic efforts benefited organizations such as the Children’s Home Society of Florida and the Hibiscus Children’s Center. Through these events, the couple raised substantial contributions for youth outreach, family support, and community programming. Their generosity became a defining element of the estate’s public identity and strengthened the family’s bond with the Treasure Coast community.
Born with a strong entrepreneurial spirit, Robert Eustace built his professional success in the technology sector. In 1980, he founded Applied Systems, a software company that became a leader in insurance automation and brokerage management solutions. His work helped modernize digital workflows in insurance, and the company’s continued relevance reflects his long-term influence on the industry. His achievements allowed him to invest deeply in his passion for architectural design, philanthropy, and community development.
Hutchinson Island remains one of Florida’s most sought-after real estate markets, known for luxury properties, pristine beaches, and exceptional fishing. The Eustace mansion, valued at more than $25 million, ranks among the island’s most expensive private homes and was recognized as Martin County’s largest residence as of 2019. Although the island features numerous high-end properties, the Eustace estate remains one of its most distinctive landmarks.
Robert Eustace is remembered not only for his achievements in technology and real estate but also for his warm presence, charitable spirit, and dedication to community enrichment. His influence will continue to shape Jensen Beach, Hutchinson Island, and the many lives touched by his generosity. His family, friends, and community now honor his memory while preserving the legacy he built on Florida’s Treasure Coast.
