Interiors are pure Piero Lissoni: an open Dada kitchen with integrated Gaggenau appliances, honed stone baths, and a restraint that lets the architecture and your art do the talking. A separate powder room makes entertaining effortless. One assigned garage space included.

Designed by Arquitectonica for Consultatio and completed in 2016, Oceana occupies 5.5 acres and 400 feet of private Atlantic beachfront on the former Bal Harbour Beach Club site. The lobbies function as a private museum, anchored by Jeff Koons' Seated Ballerina and Pluto and Proserpina. Residents enjoy an Olympic-length lap pool, beachfront relaxation pool, oceanfront whirlpool spas, full-service spa and ocean-view fitness center, two championship clay tennis courts, private cinema, library and billiards lounge, children's playroom, Enzo Enea gardens, cabanas, beach and pool service, and 24-hour concierge and valet. Ballerina, the residents-only restaurant, sits just off the North Tower lobby.
