3,818 Square Foot Overview
This 3,818-square-foot Contemporary Coastal home combines relaxed indoor-outdoor living with a spacious single-story floor plan. With four bedrooms, five full bathrooms, one half bath, and an attached three-car garage, the design offers generous private accommodations along with substantial spaces for gathering and entertaining.
All 3,818 square feet of heated living space are located on the main level. That arrangement keeps the primary suite, secondary bedrooms, kitchen, study, laundry, and major family spaces accessible without requiring stairs.
The house measures approximately 84 feet 8 inches wide and 69 feet 8 inches deep. A 785-square-foot attached garage provides parking for three vehicles, while the impressive 792-square-foot covered lanai creates nearly another 800 square feet dedicated to sheltered outdoor living.
Standout features include a split-bedroom arrangement, dual kitchen islands, formal dining space, private study, coffered ceiling treatments, first-floor primary suite with two walk-in closets, outdoor kitchen, outdoor fireplace, and a dramatic four-panel glass opening connecting the great room with the lanai.
Exterior Appeal
The exterior brings together Contemporary and Coastal architecture with subtle Florida, Mediterranean, European, and Transitional influences. The result is a polished one-story residence that feels especially appropriate for warm climates and properties where outdoor living is a priority.
Prominent gables and a 6:12 primary roof pitch give the house a strong silhouette without creating excessive height. The maximum ridge reaches approximately 28 feet 2 inches, giving the broad one-story design enough vertical presence to feel substantial.
The facade uses clean architectural forms and a clearly defined covered entrance. Large windows help balance the exterior while suggesting the bright, open character found throughout the interior.
The three-car garage uses a front-entry configuration and is integrated into the overall architecture rather than treated as a separate structure. Thoughtful exterior materials, landscaping, and garage-door selections can help maintain the sophisticated coastal character.
At the rear, the architecture becomes strongly focused on outdoor living. The expansive covered lanai stretches across the primary gathering areas, creating a sheltered transition between the house and backyard.

Interior Character
Inside, the home emphasizes generous proportions, architectural ceiling treatments, and strong connections between rooms. Coffered ceilings introduce visual detail overhead and help selected spaces feel more finished without relying on excessive ornamentation.
The interior layout is open where family interaction matters most but more private around the bedroom areas. This balance allows the house to accommodate entertaining without sacrificing quiet spaces for homeowners, children, or overnight guests.
Natural light can play a major role in the interior. Large openings toward the lanai help bring the backyard visually into the main gathering spaces, reinforcing the relaxed coastal atmosphere.
The Contemporary Coastal character also gives homeowners considerable freedom with finishes. Light woods, natural stone, warm neutral colors, streamlined cabinetry, large-format tile, and simple modern lighting could all work naturally within the design.
Floor Plan Layout
The single-story floor plan is organized around a central gathering zone with private bedroom areas positioned away from the busiest social spaces. A split-bedroom arrangement creates clear separation between the primary suite and secondary bedrooms.
The great room serves as the central anchor and connects directly with the kitchen and outdoor living area. This makes the heart of the house feel open and social while keeping circulation straightforward.
The primary suite occupies a more private section of the home and sits near the dedicated study. This creates a comfortable owner’s wing where sleeping and work spaces can remain separated from the secondary bedroom area.
The three secondary bedrooms are positioned behind the three-car garage. Each bedroom has its own full bathroom and walk-in closet, giving children, relatives, or overnight guests a high level of independence.
A formal dining room provides another defined gathering space, while main-floor laundry adds everyday convenience. The overall layout uses its 3,818 square feet to create several distinct zones rather than simply making every room oversized.
Living Spaces
The great room is one of the home’s defining spaces. Its generous proportions create a natural destination for family gatherings, entertaining, and everyday relaxation.
The strongest feature is the four-panel glass door system opening toward the covered lanai. When opened, this large connection can make the interior and exterior feel like one continuous entertaining environment.
For homeowners in mild or warm climates, that relationship can fundamentally change how the house is used. Family gatherings can spread outdoors, while meals and conversations move naturally between the great room and covered patio.
Coffered ceiling treatments add architectural detail to the interior and help give the large gathering areas a more refined character. Furniture can be arranged around conversation zones while preserving clear movement toward the kitchen and lanai.
Because outdoor living is so closely connected to the great room, the backyard becomes a visual extension of the interior. A pool, landscaped courtyard, garden, or open lawn could further strengthen that relationship.

Kitchen Design
The dual-island kitchen is one of the most distinctive features of the floor plan. Instead of relying on a single oversized island, two separate islands provide additional work surface while allowing different kitchen activities to be organized more efficiently.
One island can focus primarily on preparation and cooking, while the second can provide casual seating, serving space, or another work zone. This separation can be especially helpful when several people are using the kitchen at the same time.
For families who cook together, the dual-island arrangement creates room to spread out. One person can prepare ingredients while another handles cleanup, serving, or casual meals without everyone competing for the same countertop.
The layout is equally useful during parties. Guests can gather around one island while the primary cooking area remains functional, making the kitchen part of the social environment without allowing visitors to interrupt meal preparation.
The kitchen also maintains a strong connection with the great room. This supports the open-concept lifestyle while giving the islands enough presence to visually define the kitchen as its own functional zone.
Bedroom Comfort
Four bedrooms provide comfortable accommodations for a family, guests, or multigenerational living. The bedroom arrangement is especially appealing because privacy is emphasized throughout the floor plan.
The first-floor primary suite is separated from the secondary bedrooms and includes two walk-in closets. Separate closets can make everyday organization easier while giving each homeowner dedicated storage.
The primary bathroom has a spa-inspired arrangement with a freestanding tub positioned in front of an oversized shower. Two vanities provide individual preparation areas and help reduce congestion during morning routines.
Direct access from the primary suite to the covered porch is another valuable feature. Homeowners can step outside from their private bedroom area and enjoy the backyard without moving through the main living room.
The three secondary bedrooms are grouped in their own section behind the garage. Each has a private full bathroom and walk-in closet, creating a suite-like arrangement that works particularly well for older children or long-term guests.
Private Study
A dedicated study is positioned near the primary suite, providing a quiet room away from the secondary bedroom wing. This makes it particularly useful for homeowners who work remotely or need a focused environment for business and household tasks.
The room can accommodate a substantial desk, storage cabinetry, bookshelves, and comfortable seating. Because it is a permanent dedicated space, work equipment does not need to take over a bedroom, kitchen counter, or corner of the great room.
Its location near the owner’s suite can also make it useful as a private library or reading room. Homeowners who do not require a full-time office could create a quiet retreat for books, hobbies, planning, or personal projects.
For couples with different schedules, having a study outside the primary bedroom itself provides useful separation. One person can work or read without disturbing someone resting in the suite.
Formal Dining
The formal dining room gives the house a defined setting for meals that call for something more structured than island seating. This is particularly useful for homeowners who entertain frequently or host holiday gatherings.
While the kitchen islands can handle casual breakfasts and quick meals, the dining room provides space for a full table and more traditional furniture arrangements.
Having both casual and formal dining options also gives the house greater flexibility. Everyday routines can remain relaxed while birthdays, holidays, dinner parties, and family celebrations have their own setting.
The dining room can be finished to complement the Contemporary Coastal character through simple millwork, modern lighting, natural textures, and a restrained color palette.
Outdoor Living
The 792-square-foot covered lanai is one of the most important features of this home. Its size allows homeowners to create several outdoor living zones instead of treating the rear porch as a single seating area.
A dining table can occupy one section while sofas and lounge chairs create a conversation area elsewhere. There is also room to integrate cooking and entertainment functions without making the space feel crowded.
The outdoor kitchen allows meals to be prepared close to the gathering area. Grilling, serving, and outdoor dining can happen without requiring repeated trips to an isolated cooking station elsewhere in the yard.
An outdoor fireplace adds another focal point. Seating can be arranged around the fireplace to create a comfortable evening gathering area and extend the usefulness of the lanai during cooler weather.
The four-panel glass opening from the great room strengthens the connection between indoor and outdoor living. When weather permits, opening this wall can create a large combined entertainment area capable of accommodating family and guests across both spaces.
A swimming pool would be a natural addition beyond the lanai on an appropriately sized property. Landscaping, water features, and additional patio areas could further develop the resort-inspired coastal atmosphere.
Everyday Function
Although the house emphasizes entertaining and outdoor living, its everyday organization is equally important. Main-floor laundry keeps an essential household function convenient to all four bedrooms.
Because the home is entirely one story, clothing does not need to be carried between levels. This reinforces the practical advantages of the single-story layout.
The split-bedroom arrangement also makes daily routines easier for larger households. The primary suite has its own private zone, while secondary bedrooms are grouped together with their individual bathrooms and closets.
Five full bathrooms and a separate half bath provide substantial bathroom capacity. Family members and overnight guests have private facilities, while the powder room can serve visitors without requiring access to a bedroom bath.
These supporting features help the home function comfortably even when several people are staying under the same roof.
Garage And Storage
The attached three-car garage provides approximately 785 square feet of space. It offers parking for multiple vehicles while allowing opportunities for shelving, tools, bicycles, and other household storage.
The garage uses a front-entry configuration, making driveway planning relatively straightforward compared with designs that require a large side-entry turning court.
For households with two daily vehicles, the third bay could accommodate a collector car, motorcycle, recreational equipment, bicycles, or additional storage.
Walk-in closets in each secondary bedroom provide another important layer of organization. Combined with the two walk-in closets in the primary suite, the house offers substantial dedicated clothing and personal storage.
This closet arrangement is especially useful in a home designed for family members or guests to maintain relatively independent bedroom suites.
Special Features
The dual-island kitchen immediately distinguishes this home from many conventional four-bedroom plans. It creates additional preparation and gathering space while allowing the kitchen to handle multiple users more comfortably.
The 792-square-foot lanai is equally significant. With an outdoor kitchen, outdoor fireplace, and large glass connection to the great room, the rear living area functions as a major extension of the house.
The primary suite includes two walk-in closets, porch access, dual vanities, a freestanding tub, and an oversized shower. These features create a comfortable private retreat without requiring a separate second-floor owner’s level.
Each secondary bedroom having its own bathroom and walk-in closet is another notable advantage. This suite-style arrangement improves privacy for children, relatives, and guests.
The standard foundation uses a stem-wall system, while the main-floor exterior walls are designed with block or CMU construction. A 2×6 exterior wall option is also available. The primary roof uses a 6:12 pitch with truss framing.

Family Lifestyle
This Contemporary Coastal home is particularly well suited to families who enjoy entertaining and spending significant time outdoors. The great room, dual-island kitchen, formal dining room, and expansive lanai provide several connected settings for social activity.
At the same time, the bedroom arrangement protects privacy. The primary suite occupies its own portion of the house, while the three secondary bedroom suites are grouped behind the garage.
The dedicated study supports remote work without sacrificing one of the four bedrooms. This makes the house practical for households where professional work is regularly completed from home.
One-story living also provides long-term convenience. Bedrooms, laundry, kitchen, garage access, study, and primary gathering spaces are all available without stairs.
The design can work especially well for families with older children, frequent overnight visitors, or multigenerational households because each secondary bedroom has its own bathroom and walk-in closet.
Building Considerations
At approximately 84 feet 8 inches wide and 69 feet 8 inches deep, the home requires a generous lot once setbacks, driveway space, landscaping, utilities, and outdoor living areas are considered.
The 792-square-foot covered lanai represents substantial construction beyond the 3,818 square feet of heated living space. Its outdoor kitchen, fireplace, roofing, structural supports, flooring, and potential screening should all be considered during budgeting.
Block or CMU exterior construction is particularly common in Florida and other warm-climate regions where masonry construction is widely used. Local engineering and building requirements will determine the appropriate structural system for a specific site.
Construction pricing varies considerably across the United States. As a broad preliminary planning range, a 3,818-square-foot custom Contemporary Coastal home with a three-car garage and extensive outdoor living could cost approximately $800,000 to $1.4 million before land, major site development, landscaping, pool construction, and unusually high-end upgrades.
Premium impact-rated windows, extensive masonry, custom cabinetry, luxury appliances, elaborate outdoor kitchen equipment, high-end bathroom finishes, or a resort-style pool environment could raise the total substantially.
Homeowners should obtain detailed local contractor estimates and verify wind-load requirements, structural engineering, energy codes, foundation requirements, zoning, and other building regulations applicable to the property.
Final Thoughts
This 3,818-square-foot Contemporary Coastal home combines spacious one-story living with a strong emphasis on privacy and outdoor entertaining. Four bedrooms and five-and-a-half bathrooms provide generous accommodations, while the split-bedroom arrangement gives the primary suite meaningful separation from the secondary bedroom wing.
The dual-island kitchen creates an impressive and highly functional center for cooking and socializing. A formal dining room and private study add dedicated spaces for entertaining and remote work without compromising bedroom capacity.
The 792-square-foot covered lanai is the defining lifestyle feature. An outdoor kitchen, fireplace, and four-panel glass connection to the great room allow indoor and outdoor living to work together as one large gathering environment.
For homeowners looking for a spacious Contemporary Coastal house with private bedroom suites, a three-car garage, dedicated home office, dual kitchen islands, and extensive covered outdoor living, this design offers a practical interpretation of relaxed coastal luxury.
