Robert Eustace’s 50,000 Square Foot Waterfront Mega Mansion

Jensen Beach, FL. 
The Magnificent Estate was designed by architect Mitchell Kunik of Affiniti Architects, and was built by Turtle Beach Construction Co. 
It boasts 6 bedrooms, 10 bathrooms, and a 22-car garage.

The home's 42 gothic columns, 11 domes, 11 rotundas and 10 high arched windows are visible from the beach — and beachgoers have marveled at the mansion's progress since construction began in 2002.
But now the more than $8 million project, located just north of the Jensen Beach Causeway, at 4545 N.E Ocean Blvd., is nearing completion.
The home has 20,000 square feet of living space. With the garage and decks, it totals more than 50,000 square feet. It can withstand up to 200-mile-per-hour hurricane winds. 
The mansion also has an 11,500 square-foot guesthouse with three to four bedrooms and five-and-a-half baths.
Robert Eustace, the new mansion's owner, and his wife, Elsa, will be living in the home full-time, Souza said. 

Eustace founded a company south of Chicago 20 years ago called Applied Systems Inc. His company used computer software to make insurance agencies work easier and more efficient. He now owns Insuresoft, an Illinois-based insurance computer software supplier.
Eustace, who declined to comment on his new home, owns three other properties in the county that combine for almost 90,000 square feet. According to public records, Eustace's main residence on Doubloon Drive has a total of 10,333 square feet. His other property on Doubloon Drive has 4,899 square feet. He also owns an empty lot on Sewall's Point Road.
