About This Home

Ideally positioned just half a mile from the heart of Atlantic Avenue, 401 SE 6th Street is a brand-new residence by Gulfstream Custom Homes that seamlessly blends the energy of downtown Delray Beach with the privacy of a tropical retreat. Thoughtfully designed around a courtyard-style backyard, the home creates a private outdoor sanctuary between the main residence and detached two-car garage, complete with lush landscaping, a covered patio, and a resort-style pool. The first floor is designed for effortless entertaining, with an open-concept great room, dining area, and chef's kitchen overlooking the garden and pool. Expansive glass doors fill the interiors with natural light while creating a seamless connection between the indoor and outdoor living spaces. At the front of the home, a dedicated billiard and clubroom provides an additional setting for hosting guests, relaxing, or enjoying game nights. Upstairs, a spacious loft offers flexible secondary living space and connects four generously proportioned bedrooms, including the private primary suite. Each bedroom features its own en-suite bathroom and a well-appointed closet, providing comfort and privacy throughout. The primary suite serves as a peaceful retreat with refined finishes, a spa-inspired bathroom, and generous closet space. This newly completed residence presents an exceptional opportunity to enjoy modern construction, sophisticated indoor-outdoor living, a private pool, and a two-car garage—all within walking distance of the dining, shopping, entertainment, and vibrant lifestyle of Atlantic Avenue.
