A waterfront mansion on Coconut Grove’s Battersea Road has changed hands for more than $80 million, with the seller identified as developer Philippe Harari. The sale price landed somewhere between $80 million and $100 million, according to sources including agents involved in the deal.
Harari, who owns AquaBlue Group, sold the roughly 11,000-square-foot home at 3575 Battersea Road, according to The Real Deal. The 2015-built house sits on 0.9 acres and includes eight bedrooms, eight bathrooms and one half-bath, per the outlet’s reporting. County property records reviewed by PropertyShark show the site totals 18,653 square feet and is currently assessed at $11,859,907, with property taxes totaling $289,844.
The deal also included a quarter-acre lot next door, which Harari owned through a separate LLC, the report notes. Ahead of the sale, Harari transferred ownership of the main house to a Delaware LLC in March, while the adjacent vacant lot went to an entity called Hyacinth Holdings LLC, which he appears to control, per the same account. PropertyShark’s records show the property was last sold on March 2, 2026 for just $10, consistent with an internal ownership transfer ahead of the eventual sale.

Harari controlled the Delaware LLC until July, when the entity secured a $40.1 million mortgage from J.P. Morgan Chase carrying an interest rate of 4.9 percent locked in until 2031, the article states. That LLC is managed by Michael Mustillo, who founded and serves as CEO of Select Family Office, a New York-based firm that represents high-net-worth families, according to the same reporting. Harari and Mustillo did not respond to requests for comment, the outlet said…
