The Oasis Islamorada is a waterfront estate of exceptional scale, conceived as a private Florida Keys compound where architecture, land and water come together spanning nearly 3 meticulously landscaped acres. More than 400' of shoreline, sweeping ocean views and a protected deepwater basin create a marine setting rarely available within a single residential offering. Beyond the grand porte-cochère, the single-level main residence unfolds with soaring ceilings, white oak floors and 12-foot retractable glass walls that dissolve the boundary between interior and oceanfront living. At its center, a chef's kitchen pairs a cascading Calacatta marble island with Thermador appliances and a walk-in pantry, opening seamlessly to expansive living and dining spaces. The main residence includes four bedrooms and six full baths, with an impressive primary suite featuring a fireplace, dual walk-in closets, safe room and spa bath with steam shower. Additional suites offer en suite baths, private balconies and ocean views. A detached two-bedroom, two-bath guest residence brings the estate to six bedrooms while preserving privacy between owners and guests, with substantial grounds offering extraordinary flexibility for the future. Outside, the property assumes the scale of a private resort. Two resort-style pools with spas and sun decks are joined by a summer kitchen, alfresco dining and multiple waterfront terraces. A fitness center with sauna, soundproof theater and golf simulator complete the lifestyle offering. For the yachtsman, the protected deepwater basin accommodates substantial vessels with convenient direct Atlantic access. Built with an uncompromising focus on quality, security and enduring construction, The Oasis is more than an oceanfront residence. It is a legacy-scale Florida Keys estate offering the increasingly rare combination of acreage, significant shoreline, protected deepwater dockage, multiple residences and complete privacy within one extraordinary property
