Some swimming pools are designed to create the illusion of being surrounded by water. At East Sister Rock Island in the Florida Keys, that illusion becomes reality.
Positioned just offshore from Marathon, the private island estate is wrapped in brilliant turquoise Atlantic waters, placing its resort-style pool and spa within one of the most spectacular natural settings imaginable. Listed for $16 million by Vladimir Rochebrun and Aaron Rosenthal of The Chad Carroll Group at Compass, the property demonstrates how exceptional outdoor design can complement, rather than compete with, an extraordinary waterfront location.
Spanning approximately 6.5 acres, including 5.8 acres of privately owned surrounding seabed, East Sister Rock offers a seamless blend of luxury outdoor living, boating, watersports, and sustainable island living that feels uniquely suited to the Florida Keys.
A Pool Designed to Embrace the View
When every direction offers panoramic ocean vistas, restraint becomes one of the most important design principles. Rather than overwhelming the landscape, the waterfront pool and spa have been positioned to celebrate it. The water’s edge appears to merge naturally with the surrounding Atlantic, creating uninterrupted sightlines across vibrant turquoise waters.
Whether viewed from the home’s expansive veranda or enjoyed from inside the pool itself, the setting creates an experience that feels closer to a private resort than a traditional residential backyard. The spa provides an intimate place to unwind while remaining connected to the surrounding scenery, reinforcing the relaxed pace that defines life in the Keys.
Outdoor Living Without Boundaries
The island has been carefully planned so every outdoor space encourages residents to spend more time outside. Multiple lounging areas overlook the ocean, providing quiet places to read, entertain, or simply watch boats pass through the surrounding waters. Dedicated outdoor dining spaces invite meals beneath open skies, while mature tropical landscaping introduces texture, shade, and privacy without obstructing the remarkable views.
One of the home’s signature architectural features is its expansive 12-foot-wide wraparound veranda. Functioning as an extension of the interior living spaces, it offers abundant room for relaxing throughout the day while capturing both spectacular Atlantic sunrises and colorful Keys sunsets. The result is an outdoor environment where every space feels intentionally connected.
Beyond the Pool
Of course, one of the greatest luxuries of island living is that recreation extends well beyond the pool itself. With private ownership of the surrounding seabed, East Sister Rock offers immediate access to snorkeling, paddleboarding, kayaking, fishing, and swimming in the crystal-clear waters that have made the Florida Keys one of America’s premier boating destinations.
A 100-foot deep-water dock accommodates multiple vessels, allowing owners to explore nearby reefs, sandbars, and neighboring islands with ease. The property’s included mainland dock at 99 E Ocean Drive further simplifies access between the island and Marathon. Together, the pool, dock, and surrounding waters create an outdoor lifestyle where every day offers new opportunities for recreation.
Modern Island Independence
Luxury outdoor living increasingly includes thoughtful infrastructure, and East Sister Rock has been engineered to operate as a remarkably self-sufficient property. Integrated solar and wind power systems, battery storage, backup generation, desalination technology, and substantial freshwater cistern capacity allow the estate to function independently while minimizing its environmental footprint.
This emphasis on sustainability reflects a broader trend throughout luxury residential design, where homeowners are seeking properties that combine environmental responsibility with resilience and long-term performance.
Rather than sacrificing comfort, these systems quietly support the island’s resort-style lifestyle behind the scenes.
A Backyard Unlike Any Other
Luxury pool design often aims to transport homeowners to another place. At East Sister Rock, there is no need for illusion. The surrounding Atlantic Ocean becomes part of the outdoor living experience itself.
The pool serves as the centerpiece of an environment that seamlessly connects architecture, landscape, boating, wellness, and recreation into one cohesive coastal retreat. Every element, from the expansive veranda and tropical gardens to the deep-water dock and surrounding turquoise waters, contributes to an outdoor lifestyle that few properties can match.
As private island opportunities become increasingly scarce, East Sister Rock stands out not only for its remarkable location but also for the thoughtful way its outdoor spaces embrace the extraordinary beauty of the Florida Keys.
