A HIGHLY CUSTOMIZED SHIRAZ offering 6 bedrooms, 5 full baths and 4,113 square feet in the sought-after gated community of Marbella Isles. Built in 2018 and extensively upgraded, this home combines one of the community's largest floor plans with a completely reimagined kitchen and exceptional new outdoor living designed to capture the lake view while providing an unusual degree of privacy. The thoughtfully reimagined kitchen has been completely redesigned from the original Shiraz layout, featuring an oversized island, quartz countertops, abundant cabinetry and an impressive collection of premium appliances, including Viking Professional and Thermador Professional cooking appliances, a built-in cappuccino/coffee system and two dishwashers. A large walk-in pantry provides additional storage. Hardwood flooring, plantation shutters, extensive crown molding and millwork, paneled detailing and coffered ceilings elevate the main living spaces. The first-floor sixth bedroom, complete with a closet, is currently configured as a private home office, providing valuable flexibility for guests or working from home. Upstairs, an expansive loft creates an additional media, play or living space. The primary suite offers a private balcony overlooking the pool and lake, two walk-in closets and a spacious bath with dual vanities, walk-through shower and soaking tub. Outside is where this property truly distinguishes itself. The newly completed custom pool and expansive deck are framed by a picture-window screen enclosure that preserves the lake view, while a custom-built block wall creates a remarkably private outdoor environment rarely found with a lakefront setting. The approximately 25' x 21' extended covered lanai provides substantial year-round outdoor living and entertaining space, with plumbing and electrical conduit already run beneath the deck for a future outdoor kitchen. The air-conditioned three-car garage features insulated doors, epoxy flooring and three overhead storage racks. Additional upgrades include whole-house water filtration and a dedicated reverse-osmosis drinking-water system in the kitchen. Marbella Isles offers resort-style amenities including a clubhouse, pool and spa, fitness center, indoor basketball/multipurpose court, tennis, pickleball, bocce and children's play areas, all from a highly convenient central Naples location. For buyers seeking the space and flexibility of the Shiraz without the standard builder configuration, 13715 Callisto Avenue offers something distinctly different: extensively customized interiors, a reimagined chef's kitchen, new pool and outdoor living, beautiful lake views—and the rare benefit of genuine backyard privacy".
