This beautifully renovated Katama retreat combines refined design, luxurious amenities, and thoughtfully crafted spaces. The main house features three bedrooms, including a peaceful primary suite with private deck access, a second en-suite bedroom, and a cozy bunkroom. The octagonal living room, skylit dining room with a gas fireplace, and a chef's kitchen with quartz counters and high-end appliances create inviting spaces for relaxation and entertaining. The second floor is home to a state-of-the-art theater room, designed for an unparalleled viewing experience. A 4K projector and 110-inch acoustically transparent screen deliver vivid visuals, while eight theater-quality speakers-costing over $20,000-are hidden behind the screen wall and built into the coffered ceiling to surround you with dynamic audio. This versatile space can also serve as a family room for games and gatherings. With additional room for a home office, plus the convenience of a powder room, it's an ideal multipurpose area that adapts to your needs. The detached guest retreat offers a private bedroom, a comfortable sitting area, and a full en-suite bath. Guests can enjoy movie nights with their own theater projector and automated screen, all set under soaring cathedral ceilings. A standout feature is the newly constructed exercise studio, complete with a 14-foot Endless Performance Pool (used by major universities and colleges to train their swimmers and also enjoyed by children and nonswimmers), a fully equipped gym area, and a convenient half bath. Outside, the expansive bluestone patio is perfect for al fresco dining or relaxing in the hot tub. The professionally landscaped grounds, mature gardens, and spacious lawn provide privacy and tranquility. There's also an attached heated storage room plus a separate shed, ideal for housing beach gear, bikes, and recreational equipment. With its versatile layout, premium finishes, and proximity to South Beach, this Katama property is a sophisticated retreat, designed for effortless, year-round living. As an added bonus, sellers will cover 50% of the Martha's Vineyard Land Bank fee at closing.
