About This Home

4105 Soundview Avenue

SOUND FRONT RETREAT - Designed in 1986 by architect Sanford Hanauer for his own residence and reimagined in 2011, this elegant homestead is modern luxury done the right way. Set high above the shoreline on 2.45 acres with 200 feet of direct beachfront, angled so the water is the constant-nearly every room, every day, every season. Floor-to-ceiling glass pulls in the light, while bluestone accents, wide ash plank floors, and three fireplaces keep it warm and grounded. The Eggersmann kitchen with a butler's pantry is as timeless as it is functional, ready for quiet mornings, long lunches, and the kind of dinners that start at golden hour and somehow become tradition. Outside, the 50-foot pool is set discreetly into the bluff-private, protected, yet open water views. Two additional bedrooms are positioned to work like a separate guest cottage-ideal for extended stays or flexible space for work. A loft, multiple decks, and sun-soaked patios make indoor-outdoor living feel natural-because here, the view is the backdrop to everything. The white-stained cedar exterior blends seamlessly with the landscape. From white Italian marble baths to that last ray of sunset on the patio as the sky turns soft over the Sound, this is a home designed to inspire and never lose power with a full house generator.
