The Sanctuary, a private enclave in Boca Raton listed by Forbes as one of the most exclusive gated communities in the United States, provides an appropriate setting for this contemporary masterpiece sited on two prized waterfront lots. This 12,000-square-foot estate is cast in elegance, artful accents, and resort-style sophistication. A broad canopy of arching tree branches provides cover leading to a gated courtyard entrance. It's a thread of chic comfort and mesmerizing awe that extends throughout the five-bedroom layout (with 7 1/2 baths). Spaces like the grand entertaining room with a show-stopping two-story white stone chimney, 25-foot vaulted ceiling and porcelain flooring are inviting and captivating in the same breath. The gourmet chef's kitchen, adjacent to the great room, dazzle with bright white stone countertops and cabinetry, Wolf and Sub-Zero appliances, a private butler's pantry, a separate storage room, and an oversized island with 360-degree storage, and a temperature-controlled Vindegarde designer wine vault. The kitchen and adjoining breakfast area open to an outdoor covered dining and entertaining space, perfect for enjoying a morning cup of coffee while reveling in the splendor of the estate's beautifully appointed outdoor spaces. The expansive primary quarters, spread across the entire south wing of the property, boasts a full menu of luxury features. Highlights include a sitting room/living space with a gas fireplace, an adjoining home office, oversized boutique-style closets with custom shelving (including a bonus cedar closet), and a mammoth spa-like bathroom with steam shower and soaking tub. Sliding doors off the primary bath open to a screened outdoor relaxation and massage area, complete with a soothing Bali-inspired water feature. The indoor-outdoor flow of the home seamlessly integrates entertaining spaces along the north wing of the main floor, including a theater room (with a 120-inch screen and comfortable seating for 14), and a wellness area just off the lounge with a state-of-the-art gym, full bath and commercial-sized dry sauna by Helo Finland. The sense of serenity and style extends to an exquisite exterior, highlighted by a saltwater pool with sun shelf and spa that overlooks the property's 140 feet of water frontage (with direct ocean access). The richly landscaped outdoor area enhanced by dramatic nighttime lighting also includes a summer kitchen, and a standalone cabana pavilion with a full bath and ample storage. Meanwhile, the 120-foot angled dock, with room to host two yachts, is equipped with 30 amp shore power connection.
