Vibrant accents in teal, seafoam and emerald greens, pale pink, and light blue complement Venetian plaster walls and exquisite fully custom wood finishes, create an exclusive, elevated living experience.
The first floor welcomes you through a striking iron pivot door into an octagonal entry rotunda, wrapped in custom wood paneling and floored with large Paris Casa Grey Limestone. A breathtaking suspended wood staircase frames views of the coveted ground level private pool and loggia.

Ascending to the second floor, the heart of the home unfolds with an open-concept living area framed by a seafoam green wood floating ceiling, and adorned with luxurious Minotti furniture. The Main area flows effortlessly from the state-of-the-art Bulthaup European kitchen, equipped with premium Gaggenau appliances, to the large balcony overlooking the gulf. The formal dining room, enveloped in a strikingly elegant blue Venetian plaster, is separated from the main space by a custom glass partition, while a cozy inglenook conversation area invites intimate gatherings while staying connected to the main areas. A guest master suite and powder bath complete this level.
The third floor houses the opulent primary suite, a serene retreat with an oversized private balcony showcasing sweeping Gulf views. Its boutique-style Eggersmann closet system, featuring built-in jewelry cases and a private washer-dryer, redefines luxury.
