Upon entering the gate of this walled Casa Marina estate, you know you are about to see the most stunning modern home in Key West. Enjoy the sound of rushing water as you walk through the tropically landscaped courtyard on floating steps over the beautiful koi pond to the home's entry. The front door opens to a spectacular great room. The expansive living space is breathtaking with 12.5 ceilings and an abundance of light provided by the wall of sliding glass doors and multiple sets of windows, truly one of a kind. The eye is immediately drawn to the rear yard with its infinity pool with spa, tropical landscaping and huge loggia. The loggia has a vaulted ceiling covered in individual bamboo reeds, a gas cooktop, refrigerator, dishwasher and convection/microwave. The spacious indoor kitchen is fitted with custom-made Italian cabinetry and top end appliances. A separate butler's service kitchen provides an additional dishwasher, 2 built-in wine cabinets, ice maker and multiple refrigerator drawers. Beyond the service kitchen is a large storage pantry. The left wing of the main level encompasses the primary bedroom suite with a wall of sliding glass doors opening onto the garden. The 12.5' ceilings carry into the suite complete with a fireplace and custom cabinetry. The bath has an enormous, open walk-in shower, two separate vanities, walk-in closet and a laundry room. On the opposite side of the home take the orange lacquered floating staircase to the second floor to find 2 very spacious ensuite bedrooms each with a private balcony. A second, large laundry/storage room separates the two suites. There is off-street parking for 2 cars with electric gate, landscape lighting and irrigation. This one-of-a-kind Key West home offers an incredible opportunity for the most discerning buyer.
