Welcome to an extraordinary waterfront estate at 4800 Williams Island Drive, where unparalleled luxury meets serene coastal living. This custom-built, six-bedroom, five-and-a-half-bath home is nestled within the prestigious, gated Intracoastal Waterway (ICW) community of Paradise Island, offering an exclusive lifestyle defined by sophistication and natural beauty. Step inside to discover a residence where every detail has been meticulously curated. A custom grand staircase makes a striking first impression, while five fireplaces create a warm, inviting ambiance throughout the home. The main living spaces are designed for both grand-scale entertaining and comfortable daily life. An elevator provides effortless access to all levels, and the entire home is equipped with a whole-house generator for ultimate peace of mind. Thoughtful upgrades are evident everywhere, from the recently replaced windows, doors, and exterior floors (2018) to the automated shades and built-in speakers with individual volume controls. With an impressive 300 feet of water frontage, this property is a boater's dream. The outdoor space is a private paradise, designed for relaxation and entertainment. The recently rebuilt dock (2023) features a 16,000 lb low-profile boat lift, a 35-foot floating dock, and three jet ski floats. This canal is on a regular dredging plan, ensuring easy access. Power is readily available with a 50-amp connection and a commercial gangway. After a day on the water, unwind at the incredible tiki bar, complete with a sink and refrigerator, or take a dip in the pristine pool. The pool's equipment, drains, and skimmers have all been recently replaced, and the pool itself was acid-washed for a fresh, sparkling finish. An outdoor bathroom adds convenience, while the 30 lighted palm trees and copper gutters enhance the property's stunning curb appeal. The cap of the seawall has also been redone, and the aluminum fence with a powder coat finish adds durability and style. This home goes beyond the expected with unique, custom features. The lower level is a true retreat, featuring a "Margarita room" perfect for large gatherings, complete with a wet bar, ice maker, fridge, and wine cooler. Adjacent to this is a dedicated spa setup with a sauna and steam shower, offering a private sanctuary for relaxation. The garage is also a standout, featuring direct-drive doors and a mini-split system for climate control. A reverse osmosis filter ensures pristine drinking water in the kitchen, while the abundant storage space under the house and a 7-zone irrigation system add to the home's functionality. Located in an unincorporated part of Horry County, this property offers a prime address within a prestigious community. This is more than a home; it's a legacy property!
