Description

A private sanctuary of coastal sophistication, The Oasis offers two residences spanning 2.85 meticulously landscaped acres with over 400 feet of pristine waterfront and a protected deepwater basin. Designed for elevated living, The Oasis blends resort-style amenities with the privacy and scale of a true Florida Keys compound. The grand porte-cochère entry sets the tone, leading to a single-level main residence with soaring ceilings, white oak floors, and 12' retractable glass walls that frame sweeping ocean views. The chef's kitchen is anchored by a Calacatta marble island, Thermador appliances, and a walk-in pantry, opening to a spacious great room and dining area ideal for entertaining. The main home features four bedrooms, six full bathrooms, and a soundproof theater. The primary suite is a private retreat with a fireplace, dual walk-in closets, a safe room, and a spa-inspired bath with a steam shower. Each additional bedroom includes an en suite bath, private balcony, and ocean views. A detached guest house offers two additional bedrooms and bathrooms, creating a total of six bedrooms across the estate with endless space for expansion. The summer kitchen, alfresco dining areas, and multiple lounging terraces offer seamless indoor-outdoor living. The deepwater basin accommodates larger vessels. Amenities rival a private resort: soundproof theater, fitness center with sauna, golf simulator, and two resort-style pools—each with a spa, sun deck, & outdoor entertaining spaces.
