This exceptional home, sourced with materials from around the globe, boasts just over 7,700 square feet and is the epitome of a custom build. Sitting on 1.47 acres in the highly sought-after Bryn Mawr, PA, it is close to the best shopping, dining, and within the desirable Radnor School District. 635 S Ithan was designed by architect Gordon L. Todd Associates and later brought to life by A.L. Hellmann Custom Builders. As you drive up your private brick-paved driveway, you'll be greeted by teak wood, hand-carved double doors and a grand entrance with butterfly staircases, sitting on White Italian Calacatta Gold marble flooring. The open-concept design, with 30-foot soaring ceilings and seamless room-to-room flow, includes a formal dining room, wet bar, a spacious family room with an additional fireplace, a chef's kitchen, office space, and, last but not least, your 32,000-gallon indoor pool/spa. With five additional guest bedrooms, each with its own en-suite bath, this home offers abundant space for family and friends. The kitchen was designed by a high-profile chef and includes features such as a six-burner GE stove, twin-door Sub-Zero fridge, high-powered hood vent, two islands (each with twin sinks), granite countertops, all tied together with floor-to-ceiling high-quality cabinets. Upstairs, the spa-like master bedroom and bath are a retreat, complete with a sauna, generous walk-in closets, and sophisticated finishes. A large, three-car garage adds to the convenience and luxury of this home. Additional highlights include your private 18-seat movie theater and large entertaining space in the basement.
