When I first looked at this one-story coastal contemporary house plan, I was immediately struck by how the floor plan balances openness and privacy.

At 4,665 square feet, every square inch feels intentional.

From the moment you walk through the covered entry, the flow guides you naturally from room to room, making it easy to imagine daily life here—whether it’s family routines, entertaining, or just relaxing with a book on the lanai.

Welcoming Covered Entry and Foyer

The covered entry opens to a foyer with French doors that instantly set the tone for coastal elegance.

The foyer isn’t just an entrance; it’s a central hub that visually connects to the gallery and the great room beyond.

I love how the floor plan gives a sense of arrival, and yet, you can see straight through to the lanai, inviting the outdoors in.

This layout makes it clear that functionality and style were both priorities.

The Heart of the Home: Great Room and Gallery

At the core of this plan is the great room, flanked by the gallery that creates a natural flow through the home.

This space is perfectly situated to connect the kitchen, dining area, and lanai, allowing for entertaining or casual family living.

The floor plan makes it easy to position furniture and visualize traffic patterns.

You can see how thoughtfully the layout separates activity zones without isolating anyone, making it ideal for both gatherings and quiet moments.

Kitchen and Dining Area with Smart Flow

The kitchen sits adjacent to the dining area, offering access to the lanai for seamless indoor-outdoor living.

The walk-in pantry tucked nearby ensures ample storage while keeping the layout uncluttered.

From a floor plan perspective, this area strikes a balance between efficiency and comfort, allowing multiple people to cook, dine, or relax simultaneously without feeling cramped.

It’s a design that anticipates real-life use, from daily meals to hosting family and friends.

Study Off the Gallery: Work and Privacy

One of my favorite floor plan features is the work-from-home study located just off the gallery.

Barn doors provide privacy while maintaining visual flow when open.

This placement allows you to stay connected to the central spaces without sacrificing concentration.

The plan makes it easy to integrate home office furniture and technology without disrupting the balance of the main living areas.

Right Wing: Three Bedrooms with Ensuite Baths

The right side of the house is dedicated to three bedrooms, each with its own ensuite bathroom.

This layout ensures privacy while maintaining proximity for family interaction.

A nearby laundry room and mud area connect directly to a 2-car garage, making this wing extremely functional.

The floor plan cleverly balances private and utility spaces, showing attention to how families live day-to-day.

Master Suite Wing for Ultimate Privacy

The master suite occupies its own wing across the home, offering a private retreat.

It includes a sitting room that opens to the lanai, perfect for enjoying morning coffee or evening sunsets.

The master bath features a private outdoor shower, adding a luxurious coastal element.

From a floor plan perspective, separating the master wing from the other bedrooms ensures both quiet and intimacy while maintaining convenient access to the home’s core spaces.

Dual 2-Car Garages: Flexibility and Storage

This house plan includes two 2-car garages totaling 1,565 square feet.

One connects to the right wing via the mud area, while the other is positioned for additional storage or vehicle access.

The layout allows flexibility for vehicles, storage, hobbies, or even a workshop.

The garages are thoughtfully incorporated into the floor plan so they don’t dominate the façade, yet they provide significant functional space.

Covered Outdoor Living: Lanai Integration

The plan includes 1,025 square feet of covered outdoor space, primarily via the lanai, which is directly accessible from both the great room and the master suite.

Its placement encourages indoor-outdoor living without disrupting the flow of the interior.

From a design standpoint, the lanai feels like a natural extension of the home rather than an afterthought, enhancing both entertainment options and daily enjoyment.

Efficient Traffic Flow

One of the strongest aspects of this floor plan is the circulation.

The gallery connects the foyer to all major spaces, allowing smooth movement from the bedrooms to the great room and outdoor areas.

Even with multiple people moving through the home at once, the layout prevents bottlenecks.

The positioning of the mud area and laundry room near the garages also reduces congestion and makes everyday tasks—like unloading groceries—more convenient.

Bedrooms Designed for Comfort and Privacy

Each of the four bedrooms is thoughtfully positioned to balance access to shared spaces with personal privacy.

The floor plan provides separation between guest and family areas while ensuring the master suite remains a serene retreat.

Ensuite bathrooms in all bedrooms add functionality and a sense of luxury, keeping morning routines stress-free and preserving harmony in a busy household.

Functional Zones Without Compromise

Looking at the floor plan as a whole, you can see how the design smartly separates activity zones.

The right wing focuses on family and guest bedrooms, the master suite wing offers private luxury, and the central zone connects living, dining, and kitchen spaces.

Even with a large footprint, the plan feels intimate rather than sprawling, thanks to clear delineation of functional areas.

Maximizing Usable Space

With 4,665 square feet of heated living space, the plan makes efficient use of every square foot.

There’s no wasted hallway space, and the layout maximizes natural light and outdoor views.

The integration of storage solutions in the garages, pantry, and mud areas further demonstrates the plan’s thoughtful approach to everyday living needs.

Indoor-Outdoor Connection

A key feature of the floor plan is how it embraces the coastal lifestyle.

Multiple access points to the lanai from both the great room and master suite create seamless transitions between indoor and outdoor spaces.

This integration not only enhances entertaining opportunities but also makes the home feel open and airy, emphasizing a connection to nature without sacrificing privacy.

Future Flexibility

This plan also anticipates changes in lifestyle.

Whether you want to adapt rooms for a home gym, office, or hobby area, the layout allows for customization without disrupting the core flow.

The dual garage spaces provide additional options for storage or workshop needs, and the clear zoning ensures that modifications won’t compromise comfort or aesthetics.

In summary, the one-story coastal contemporary house plan balances luxury, functionality, and flexibility.

Its thoughtful zoning separates private and shared spaces, while the central gallery connects everything smoothly.

From the covered entry to the dual garages, the lanai, and private master wing, every area feels intentional and livable.

The plan’s layout encourages both family interaction and private retreat, making it an ideal blueprint for modern coastal living.
