One hundred feet of Gulf frontage, three-quarters of an acre, and a house designed by Michael O’Donnell, in the spirit of the Sarasota School of Architecture style, to make the most of this property. Elevated above the pool and garden, almost every room is open to the water. Floor-to-ceiling glass spans the entire Gulf side, so the horizon is part of the room from morning through sunset. Balconies float above the screened pool and gardens. The outside is welcomed inside. The floor plan is an H shape, and it works the way a house like this should. On one side, the living room and dining room enjoy high ceilings, and a staircase wraps around an elevator. There’s also a flex room with its own balcony, and half bath, which could be a guest retreat, a study, or whatever you need it to be. On the other side are three bedrooms, two baths, and laundry; quiet and private. The primary suite opens to a Gulf-facing balcony and has a walk-in closet and ensuite bath. The second bedroom has an east-facing balcony for coffee in the morning sun. The third bedroom is tucked between them with south-facing windows. The kitchen acts as a bridge between the two sides of the house, with walls of windows to the east and west and a breezeway running beneath. Open and spacious; light crosses it all day, and so does the breeze. It features a Viking range and a long island with a vivid blue countertop. Beneath the house, you’ll find a two-car garage and a large storage room, ready to become a workshop, gym, or additional garage space. A private path leads to your deeded beachfront. Newly planted landscaping, an outdoor shower, a gas hookup for grilling, and rooftop solar complete the picture.
