The total heated living area spans 4,068 square feet and includes four bedrooms, four and a half bathrooms, and a three-car garage.
Exterior and Overall Design
This home boasts a coastal architectural style featuring a low-pitched roof and clean horizontal lines. A broad front porch greets guests and opens into a well-lit foyer with a direct view into the expansive great room.
The exterior walls are block construction (CMU), making it well-suited for coastal climates with durability and storm-resistance in mind. The 4:12 truss roof system contributes to both structural integrity and aesthetic charm.
Main Living Areas
The open-concept layout is central to this home’s design. The great room seamlessly connects with the kitchen and dining areas, allowing smooth transitions for both daily activities and entertaining.
A large kitchen island sits at the heart of the space, while the walk-in pantry is discreetly positioned for utility without disruption. Natural light floods the area through wide sliding doors that open to a covered lanai, enhancing airflow and inviting outdoor interaction.
Private Bedroom Suites
The master suite is positioned on the right side of the home, providing a private retreat complete with direct lanai access. It features two spacious walk-in closets and a luxury bathroom with dual vanities, separate toilets, a freestanding soaking tub, and a large walk-in shower.
Three additional bedroom suites are distributed across the opposite side of the home. Each includes its own private bathroom, making this plan ideal for families, guests, or vacation rental scenarios. The thoughtful separation of the master and guest suites ensures privacy for all residents.
Home Office and Additional Features
A dedicated study is located just off the foyer, suitable for remote work or a quiet reading room. Adjacent to the garage is a spacious laundry and mudroom combination with built-in lockers, helping manage clutter after a beach day or from daily use.
Outdoor Living and Entertainment
The rear lanai, measuring 516 square feet, is equipped with an outdoor kitchen. This makes it an excellent space for hosting outdoor meals or relaxing in the coastal breeze. Whether grilling for family or entertaining guests, the lanai extends the living area without adding structural complexity.
Garage and Utility Spaces
The 3-car garage includes 782 square feet of covered parking, accessible through a small entry foyer connected to the mudroom. The garage placement also creates a semi-private motor court layout, ideal for homes on corner lots or narrow plots.
