Behind the gates of Naples' most exclusive enclave, on a rare double-lakefront homesite, stands a residence that answers to nothing around it. The Estates at Bay Colony represents the pinnacle of luxury living in Naples, and this extraordinary residence stands apart even here. Set across approximately 1.42 acres, the estate encompasses more than 15,000 square feet of living space, surrounded by sweeping lake and golf course views. Timeless European architecture sets the tone. Exceptional craftsmanship and uncompromising finishes carry throughout the home, creating spaces that feel grand without sacrificing warmth or livability. The interiors were designed for both private living and exceptional entertaining. Separate his-and-her studies offer individual retreats, while a hidden pub and billiards room provide an unexpected escape. A private theater creates an intimate setting for movie nights and entertaining. The first-floor primary suite is a world of its own. A private sitting room, dual dressing rooms and a spa-inspired bath create a secluded sanctuary within the estate. Outside, the property becomes a private resort. Beyond the screened loggia, a full summer kitchen and bar open to expansive entertaining areas. A magnificent pergola and elegant cabanas frame the grounds, while a 50-foot lap pool, water lounge and spa overlook the lake. A separate two-bedroom guest house offers its own full kitchen and living area, providing complete privacy for family and guests. Garage accommodations for up to six vehicles, along with dedicated golf-cart storage, complete the property. Rarely does a Naples residence combine this level of acreage, privacy, architectural presence and resort-style living. Within the already exclusive Estates at Bay Colony, 9663 Mashie Court is an estate in a class entirely its own.
