Sometimes the perfect floor plan doesn’t come in a mirror image.

In this case, it comes in two wonderfully asymmetric units housed under one stunning coastal contemporary roofline.

With 3,466 square feet of total heated living space, this one-story duplex is designed for versatility, privacy, and style—all without sacrificing comfort.

Whether you’re planning to live in one unit, rent both, or turn the whole property into a smart long-term investment, this layout checks every box and then some.

Two Asymmetric Units with Distinct Floor Plans

At first glance, you’ll notice this isn’t your average side-by-side setup.

Unit A and Unit B are thoughtfully laid out to cater to different needs while maintaining cohesive design.

Unit A, on the left, includes 1,575 square feet with 2 bedrooms, 2 full baths, and a den for added flexibility.

It’s a great fit for couples, retirees, or anyone who appreciates space without too much upkeep.

Unit B, on the right, stretches out to 1,891 square feet, offering 3 bedrooms and 3 full baths—perfect for larger families or those who need the extra room.

The beauty of this design is that both units feel like independent homes rather than halves of a duplex.

This thoughtful arrangement increases the home’s property value and broadens its appeal for various buyers.

One-Story Floor Plan with Easy Accessibility

Built on a single level, this home offers easy, stair-free living in both units—ideal for aging in place, small children, or anyone who simply doesn’t want to lug groceries up flights of stairs.

The slab foundation and CMU (block) exterior walls provide strength and durability, particularly important in coastal regions.

A single-story layout also streamlines interior flow.

Moving between rooms feels effortless, which adds to the home’s sense of spaciousness.

Plus, for those who like to plan ahead, it’s a floor plan that can easily be adapted for future needs without major renovation—a bonus when applying for home improvement loans or working with a home remodeling contractor down the line.

Private Bedroom Zones for Ultimate Comfort

One of the smartest design choices in this duplex is the split bedroom layout featured in both units.

Rather than clustering all the bedrooms together, each primary suite is located on the opposite side of the home from the secondary bedrooms.

This makes the layout ideal for privacy, noise reduction, and overall comfort.

In Unit A, the 2-bedroom layout is enhanced by the central positioning of the living and dining areas, separating the bedrooms naturally.

Unit B follows suit, giving the primary suite a retreat-like feel while the other two bedrooms remain tucked away.

Whether you’re living with family or renting the unit out, the split layout appeals to everyone—especially when working with a real estate agent to market the home.

Flexible Living Spaces with Open Concept Design

Both units offer open-concept living areas, which help the home feel airy, bright, and connected.

The kitchens flow directly into the dining and living spaces, encouraging easy conversation, relaxed gatherings, and practical movement throughout the home.

In Unit A, the adjoining den adds a layer of flexibility.

Need a home office, reading room, or craft space?

The den has you covered.

It’s a perfect bonus that boosts the usability of the floor plan without increasing the square footage.

Unit B, with its extra room, opens up even more possibilities.

Larger living areas accommodate bigger furniture, extended dining tables, or even the addition of custom storage.

And if you’re thinking about upgrades, tools like interior design software or a building cost estimator can help you visualize changes before making the leap.

Outdoor Living with Covered Lanais

This is a coastal floor plan, after all—so it only makes sense that both units come with private covered lanais.

These outdoor spaces act as an extension of the indoor living areas, providing a shady, breezy spot to enjoy your morning coffee or host an evening dinner with friends.

Having a covered lanai adds livability and boosts property value, especially in warmer climates where year-round outdoor time is a selling point.

If you’re financing the home, features like these can help justify your home loan pre-approval amount—and they’re appealing assets for future resale or rental potential.

Garage Space for Two Cars in Each Unit

Garages don’t always get the love they deserve, but this duplex takes them seriously.

Both units include a 2-car garage—514 square feet in Unit A and 506 square feet in Unit B.

That’s plenty of space not just for your vehicles, but for storage, sports equipment, or even a small workshop.

And if you’re thinking ahead, the garages are well-suited for installing smart home technology or even a component of the best home security system.

Plus, having a dedicated garage for each unit increases the home’s investment value and makes it more attractive to future renters or buyers.

Durable Construction with Coastal Resilience

This home is built for the environment it lives in.

The slab foundation and CMU (block) exterior walls aren’t just durable—they’re practical choices for withstanding coastal weather conditions.

It’s the kind of construction that keeps maintenance low and helps reduce home insurance costs over time.

For buyers looking to purchase a property with longevity, this layout offers peace of mind.

And for those planning to refinance mortgage or take out a home equity loan later, the quality of construction only adds strength to your financial position.

Independent Entrances for Complete Separation

While both units share the same footprint, they each include their own private entrance, offering full separation between the two households.

This level of privacy makes the floor plan especially appealing for multi-generational living, long-term rentals, or even dual ownership.

Having independent entries also simplifies management if you’re using one or both units as rentals.

It offers clear boundaries and adds appeal in today’s competitive housing market, where renters increasingly value privacy and autonomy.

Adaptable for Personal or Rental Use

What makes this floor plan so valuable is its adaptability.

Live in one unit and rent the other.

Keep both for yourself—perhaps one for living, the other as a home-based business space or guest quarters.

Or rent both and let your investment earn monthly income.

Because each unit is self-contained and includes its own bedrooms, bathrooms, garage, lanai, and entry, the home functions as two standalone residences under one roof.

That means more flexibility when working with lenders, better returns if you decide to rent, and higher appraisal value when considering a refinance or sale.

This coastal contemporary duplex floor plan isn’t just a pretty face—it’s a thoughtfully designed, well-balanced home made for real life.

From the asymmetrical layout and split bedrooms to the open living areas and outdoor lanais, every square foot has been crafted with care.

If you’re exploring your options to buy, build, or make a solid investment, this floor plan gives you both beauty and brains.

Add in the ability to work with a home remodeling contractor, explore smart upgrades, or apply for a home improvement loan, and you’ve got a property that can evolve with your life.

Ready to move in?

Or at least to dream a little?

Either way, this duplex floor plan is a coastal winner with room for real growth.
