Property Description

This oceanfront penthouse is for the discerning few—those who seek a residence that is truly one of one. Arrive via private elevator into a full-floor home defined by floor-to-ceiling glass and sweeping 180-degree ocean views. A dedicated on-site property manager and personal concierge are central to the ownership experience, providing daily oversight and seamless support. From property management, maintenance coordination, and storm preparation to seasonal check-ins, arrival readiness, and security monitoring, every detail is professionally handled. The concierge also manages daily lifestyle needs—grocery and pharmacy deliveries, housekeeping coordination, service scheduling, reservations, and move-in or seasonal transitions—delivering true lock-and-leave ease. Completely reimagined in 2024, the building underwent a full-scale renovation, elevating every element to modern luxury standards. As the finest of just four residences, this penthouse offers the privacy of a boutique building with the sophistication of new construction. Built by Ellemar, the residence reflects an uncompromising commitment to quality and design. Ideally positioned between Palm Beach and Miami, this is a refined alternative to a custom beachfront estatewithout the upkeep. Rare, turnkey, and irreplaceable.
