This elegant, single-story beach house delivers approximately 4,068 sq ft of luxurious coastal living. Featuring 4 ensuite bedrooms, a powder room, and a seamless indoor-outdoor design with a sprawling 516 sq ft lanai, this home crafts a dynamic, breezy lifestyle perfect for both grand entertaining and peaceful seaside retreats. 1

Indoor–Outdoor Harmony

Wide-open spaces define the heart of the home. The great room, drenched in natural light, flows directly into the kitchen, anchored by a massive island—effortlessly blending cooking, lounging, and entertaining zones. A breakfast nook overlooks the generous lanai, and the nearby hidden pantry keeps storage sleek and functional. 2

Elegant Entertaining Spaces

Host with style from the formal dining room or retreat to the peaceful study-stocked library. This home offers both refined sophistication and everyday practicality. 3

Private Master Suite Retreat

Nestled in its own wing, the master suite includes private lanai access, dual closets, dual commode rooms, and a spa-like bathroom with a freestanding tub in front of an oversized shower—an oasis for calm and comfort. 4

Each Guest Gets Their Own Suite

Three additional bedrooms offer complete privacy, each with its own full bath. Ideal for family or guests, everyone gets their own sanctuary. The protruding 3-car courtyard-access garage leads directly into a mudroom/laundry zone that keeps life from tracking inside. 5
