As peak hurricane season approaches, there’s no better time to consider a mansion that not only has all the accouterments a luxury buyer seeks but also the latest in hurricane protection.

Located on a 16,000-square-foot oceanfront lot at 7815 Atlantic Way in Miami Beach, the 9,585-square-foot estate has five bedrooms, six full and one half baths, two kitchens, a theater, three built-in wine cellars, three fireplaces and a guest house. Outside, there’s a saltwater pool, Jacuzzi, built-in cabana, fire pit, summer kitchen, a large manicured backyard and 60 linear feet of direct ocean frontage. The property is listed for $19.25 million.

The three-story modern mansion was built in 2015 with impact doors and windows and concrete and steel reinforcements that enable it to withstand winds of 257 miles per hour. It also has a generator to power the entire property.

“The house is designed really well and built to the highest level of construction standards,” said Miltiadis Kastanis, a director of luxury sales with Douglas Elliman Real Estate in Miami Beach, who holds the listing.

The mansion is located in Altos Del Mar, which Kastanis said is the only oceanfront single-family home community in Miami Beach. “It translates to ‘heights above the sea,’ so it’s naturally elevated,” he said. “It’s a gated community just south of the North Shore Open Space Park.”

The estate is owned by Mark Keller and Carolyn Keller, his wife. Mark Keller is chairman of Edge Fund Advisors, a real estate investor, investment advisor and asset management firm headquartered in Washington, D.C. He has over 38 years of commercial real estate experience and has developed, acquired and managed over $7 billion in real estate investments. Carolyn Keller is founder of EBeauty, a nonprofit organization whose mission is to enhance and strengthen the education, charitable and community support for women undergoing cancer treatments.

The couple purchased the land in May 2012 for $3.5 million and built the house. They plan to downsize but remain in the area, Kastanis said.
