The properties will be part of Heinrich von Hanau's 12-lot Links Estates project, which Madar Group acquired for $40 million. The mansions will span between 8,000 and 15,000 square feet, and Madar is considering combining lots to build a larger estate worth up to $100 million.

His net worth is estimated at $1.1 billion by Forbes. David-Emmanuel Cohen, CEO of Madar Group USA, revealed that one of the spec mansions has already been presold.

    Fredrik Eklund and Dina Goldentayer of Douglas Elliman are leading sales for the Madar mansions, highlighting Fisher Island's exclusivity and security as a major draw for luxury buyers. "It's its own world," Eklund said. "The island has such cachet and it's starting to attract younger and international buyers."

    Fisher Island is one of the wealthiest communities in the US, accessible only by ferry, boat, or helicopter. The island boasts a private school and golf club, highly sought-after amenities in today's market. Heinrich von Hanau launched sales for Links Estates in 2022 with prices starting at $33 million, selling two lots to Randall Fiorenza for $13 million.

    The ultra-luxury project is not the only high-end development on Fisher Island, as billionaire Jorge Pérez's Related Group and other partners are working on a 10-story condo complex with prices reaching up to $150 million per penthouse.
