<\/h2>\n

This 3,818-square-foot contemporary coastal house plan is designed for buyers who want a spacious one-story home with a refined look, generous outdoor living, and a layout that balances entertaining space with private bedroom zones. The plan includes four bedrooms, five full bathrooms, one half bath, and an attached three-car garage, all arranged on a single level with a strong emphasis on comfort, convenience, and upscale everyday living.<\/p>\n

At its core, this home is about flow. The main living areas are open and inviting, the lanai is large enough to function like an outdoor room, and the split-bedroom arrangement gives the primary suite its own private side of the house. A dedicated study adds flexibility for work-from-home life, while the secondary bedrooms each enjoy their own bathroom and walk-in closet, making the plan especially attractive for families with older children, frequent guests, or multi-generational living needs.<\/p>\n

The design also leans into the indoor-outdoor lifestyle that many coastal and warm-climate buyers are looking for. Large glass doors connect the great room to the lanai, the outdoor living space includes both a fireplace and an outdoor kitchen, and the primary suite opens directly to the rear porch. Together, those features make the house feel larger than its square footage suggests because so much of the living experience extends beyond the interior walls.<\/p>\n

Exterior and Curb Appeal<\/h2>\n

The exterior combines coastal ease with a more polished contemporary presentation. It has the clean lines and airy feel often associated with Florida and Mediterranean-inspired homes, but it avoids looking overly ornate or formal. Instead, the design stays grounded in simple roof forms, balanced proportions, and a wide one-story footprint that feels elegant without becoming flashy.<\/p>\n

At 84 feet 8 inches wide and 69 feet 8 inches deep, the home has a substantial presence on the lot. That width allows the fa\u00e7ade to stretch comfortably across the front elevation, which is especially effective in a one-story design because it gives the house a broad, established look rather than a tall, narrow silhouette. The attached three-car garage is integrated into the front of the plan, but the overall composition still keeps the house feeling residential and welcoming rather than garage-dominant.<\/p>\n

The architectural style draws from several influences, including coastal, contemporary, transitional, and Mediterranean ideas. That blend works in the home\u2019s favor because it creates a design that feels regionally appropriate in warm climates while still offering a timeless quality. The front elevation likely presents a clean combination of stucco or masonry surfaces, large windows, and strong rooflines, all contributing to a home that looks custom-built rather than generic.<\/p>\n

With a maximum ridge height of 28 feet 2 inches, the house has enough vertical presence to feel substantial, but it still maintains the low-slung profile that makes one-story living so appealing. The result is a home that looks sophisticated from the street while still promising comfort and livability inside.<\/p>\n

<\/p>\n

Porch and Outdoor Living<\/h2>\n

Outdoor living is one of the biggest strengths of this house plan. The rear lanai spans an impressive 792 square feet, which is far more than a simple patio cover or small porch addition. This is a true extension of the living space, designed to function as an outdoor gathering area for relaxing, dining, and entertaining.<\/p>\n

The great room opens to the lanai through a four-panel glass door, which helps blur the line between indoors and outdoors. That wide opening is a major asset in a coastal home because it lets the rear porch become part of the main living experience rather than a disconnected feature in the backyard. On mild days, homeowners can open the house to the lanai and enjoy the sense of space and airflow that makes warm-weather living so attractive.<\/p>\n

The lanai also includes an outdoor fireplace and an outdoor kitchen, both of which add real day-to-day value. The fireplace makes the porch feel more like a finished living room than a covered patio, giving it a focal point and making it more comfortable during cooler evenings. The outdoor kitchen, meanwhile, turns the lanai into a practical entertaining zone where meals can be prepared and served without constantly moving back and forth through the main kitchen.<\/p>\n

Another important detail is that the primary suite has direct access to the covered porch. That creates a more private connection to the outdoor space and makes the owner\u2019s suite feel even more retreat-like. Whether the homeowners want a quiet morning coffee spot, a place to unwind in the evening, or easy access to the lanai without crossing the public areas of the house, that connection adds a layer of comfort that is easy to appreciate in daily use.<\/p>\n

2D Floor Plan and Interior Layout<\/h2>\n

The floor plan is arranged around a central living core with private wings extending outward, which is one of the most effective ways to organize a large one-story house. Instead of simply placing rooms in a straight line, the design uses a split-bedroom layout to separate the primary suite from the secondary bedrooms while keeping the main gathering spaces in the center of the home.<\/p>\n

At the heart of the plan is the great room, which acts as the main living and entertaining hub. From there, the kitchen, dining area, and lanai all connect naturally, allowing people to move through the house without awkward dead ends or long wasted hallways. This kind of arrangement is especially important in a home of this size because it helps the square footage feel purposeful rather than spread out for the sake of size alone.<\/p>\n

The primary suite occupies one side of the house, giving it more privacy from the rest of the bedroom spaces. A study sits nearby, which is a smart placement for homeowners who want a quiet office, library, or flexible retreat close to the owner\u2019s suite. That study can easily serve as a dedicated work-from-home space, but it could also function as a reading room, planning room, or secondary lounge depending on the household\u2019s needs.<\/p>\n

On the opposite side of the home, the secondary bedrooms are tucked behind the three-car garage. This arrangement helps keep the children\u2019s or guest wing separate from the owner\u2019s side of the home, which is one of the major advantages of the plan. Each of those bedrooms includes its own full bathroom and walk-in closet, so they are not treated like leftover spaces. Instead, they feel more like private suites, which is ideal for older children, overnight visitors, or extended family members who may need a more comfortable long-term setup.<\/p>\n

The layout also appears to support efficient daily traffic. Guests can enter the home and move toward the public spaces without crossing into the private bedroom wings. At the same time, family members can move from the garage into the service areas and kitchen without cutting through formal entertaining spaces. That separation between guest circulation and everyday household circulation is one of the reasons the plan feels so well thought out.<\/p>\n

<\/p>\n

Kitchen, Dining, and Great Room Design<\/h2>\n

The kitchen is built for both function and social interaction, which is exactly what buyers tend to want in a home of this size. A dual-island layout immediately sets this space apart from a more standard kitchen arrangement. With two islands, the room gains extra prep space, more seating potential, and better flexibility for hosting. One island can handle meal prep while the other works for serving, casual dining, or conversation, which is especially useful during holidays or larger gatherings.<\/p>\n

Because the kitchen sits so close to the great room, it becomes part of the home\u2019s social center rather than a separate work zone. That makes it easier for the cook to stay involved in family life, whether children are doing homework nearby, guests are gathered around the island, or friends are moving in and out to the lanai. In practical terms, the kitchen is likely to become one of the most-used spaces in the home, not just for cooking but for everyday connection.<\/p>\n

The great room itself is described as generous, and that scale matters in a house with nearly 4,000 square feet of living space. It needs to feel large enough to anchor the home, and it appears to do exactly that. Coffered ceiling treatments add architectural detail overhead, giving the room a more finished and upscale look without relying on unnecessary complexity. Those ceiling details also help visually define the great room within the larger open layout.<\/p>\n

A formal dining room is another important feature of the plan. It gives the home a dedicated place for holidays, dinner parties, and family celebrations without forcing every meal to happen in the kitchen or great room. For some buyers, that separate dining space is still an essential part of a luxury family home because it provides flexibility for both casual and more formal occasions.<\/p>\n

Overall, the kitchen, dining, and great room areas are designed to work as one connected living environment. They support daily routines, larger gatherings, and indoor-outdoor entertaining with equal ease, which is one of the reasons the home feels so complete.<\/p>\n

Bedrooms and Bathrooms<\/h2>\n

This house plan includes four bedrooms, five full bathrooms, and one half bath, which gives it a very generous level of comfort for both family members and guests. The bedroom count is ideal for a full household, while the bathroom count provides a level of privacy that is hard to overstate. In a plan of this size, it is not just about having enough sleeping rooms. It is about making those rooms comfortable and independent enough to feel truly useful.<\/p>\n

The primary suite is clearly intended to be a standout feature. It includes two walk-in closets, direct access to the covered porch, and a spacious bathroom with two vanities, a freestanding tub, and an oversized shower. That arrangement gives the owner\u2019s suite a resort-like feel while still staying practical for daily use. Dual closets help reduce crowding and improve storage, and the porch access creates a more private connection to the outdoor living areas.<\/p>\n

The primary bathroom is especially strong because it is designed around both comfort and convenience. Two vanities help the space function well for a couple, while the freestanding tub and oversized shower add a more luxurious tone. In a home where the owner\u2019s suite is meant to feel like a retreat, those details matter.<\/p>\n

The secondary bedrooms are equally impressive in their own way. Each one is paired with its own full bathroom and walk-in closet, which is a major benefit for guests, teenagers, or multi-generational living. Rather than sharing a hall bath and a small closet, each room gets a more self-contained setup. That makes the secondary bedroom wing feel much more generous and helps the home support a variety of living arrangements over time.<\/p>\n

The additional half bath is also useful, especially when entertaining. It allows guests to use a powder room near the public spaces instead of entering private bedroom bathrooms, which improves both convenience and privacy during gatherings.<\/p>\n

<\/p>\n

Laundry, Storage, and Functional Areas<\/h2>\n

A home of this size needs strong support spaces, and this plan includes the kind of practical features that help the square footage function well day after day. The laundry room is located on the main level, which is exactly where it belongs in a one-story house designed for long-term convenience. Keeping laundry on the same floor as all four bedrooms makes the daily routine simpler and reduces unnecessary trips across the house.<\/p>\n

Storage is another area where the plan should perform well. The three-car garage alone provides 785 square feet of utility space, which can do far more than simply hold vehicles. Homeowners can use part of that area for tools, sports equipment, holiday decorations, outdoor gear, and workshop storage, all without crowding the interior of the house. In a larger family home, that extra garage square footage is often one of the most valuable practical features.<\/p>\n

The study also adds functional flexibility. While it is easy to think of it primarily as an office, it can just as easily become a quiet media room, a planning room, a homeschool space, or a private sitting room off the primary suite. The value of a room like this is that it gives the home an adaptable space that is separate from both the main living areas and the bedrooms.<\/p>\n

The split-bedroom arrangement itself is also part of the home\u2019s functional design. It improves privacy, reduces noise transfer between the owner\u2019s suite and the secondary bedrooms, and makes the house easier to live in when different members of the household keep different schedules. That kind of separation is especially helpful in homes with teenagers, guests, or family members who work from home and need quiet during the day.<\/p>\n

Structure and Specifications<\/h2>\n

From a planning standpoint, this house has a strong set of specifications for a luxury one-story coastal home. The heated living area totals 3,818 square feet, all on the first floor, which makes the home especially attractive for buyers who want generous space without stairs. The front entry covers 74 square feet, while the lanai adds another 792 square feet of outdoor living space, giving the home a very strong indoor-outdoor profile.<\/p>\n

The home measures 84 feet 8 inches wide by 69 feet 8 inches deep and includes an attached front-entry three-car garage with 785 square feet of space. The standard foundation is a stem wall, and the main exterior wall construction is listed as block or CMU, with an optional 2×6 wall system available. That kind of construction profile makes sense for many coastal and Florida-style markets where durability and local building practices are important considerations.<\/p>\n

The primary roof pitch is 6:12, and the framing type is truss. These technical details matter because they help shape both the exterior appearance and the overall construction approach. The plan\u2019s one-story footprint, broad width, and substantial outdoor living space all point to a home designed for comfort, entertaining, and long-term livability rather than for compact lot efficiency.<\/p>\n

Architecturally, the home crosses several categories, including coastal, contemporary, European, Florida-style, Mediterranean, and transitional influences. That blend helps explain why the design feels both elegant and relaxed. It has the outdoor emphasis and breezy openness associated with coastal living, but it also carries the more polished room planning and detail level of a larger custom home.<\/p>\n

<\/p>\n

Lifestyle and Estimated Build Cost<\/h2>\n

This house plan is well suited for homeowners who want a high-comfort one-story layout with enough room for family life, entertaining, and overnight guests. It works especially well for buyers in warm or coastal climates where covered outdoor living is a major part of how the home will be used. The large lanai, outdoor kitchen, outdoor fireplace, and great room connection all support that kind of lifestyle naturally.<\/p>\n

The plan is also a strong fit for families who need privacy within a shared home. The split-bedroom layout keeps the owner\u2019s suite separate, the study offers quiet workspace, and the secondary bedrooms each have their own bath and walk-in closet. That combination makes the home practical for everything from teenage children to visiting relatives to long-term guests.<\/p>\n

Construction costs for a 3,818-square-foot one-story coastal home with block exterior walls, a large lanai, outdoor kitchen, outdoor fireplace, and upscale bathroom and kitchen features can vary widely by region and finish level. In many parts of the United States, a realistic broad custom-build range could fall somewhere around $260 to $420 per square foot. That would place the main home in the neighborhood of roughly $990,000 to $1,600,000 before land, site work, utility hookups, permits, landscaping, pool construction, extensive hardscaping, and high-end custom upgrades are added.<\/p>\n

In higher-cost coastal markets, especially where labor, insurance, and wind-rated construction standards are more demanding, the total could easily move above that range. In more moderate-cost areas with carefully managed finishes, it may come in lower. As always, the most accurate pricing will come from local builders who can evaluate the plan in the context of the specific lot, region, material choices, and code requirements.<\/p>\n

Final Thoughts<\/h2>\n

This contemporary coastal house plan offers a very appealing mix of one-story convenience, luxury-level comfort, and strong indoor-outdoor living. The 3,818-square-foot layout gives the home enough scale to feel substantial, but the split-bedroom design and central living arrangement keep it practical and easy to navigate. The study, dual-island kitchen, private secondary bedroom suites, and generous lanai all add value in ways that go far beyond surface-level styling.<\/p>\n

The primary suite is especially strong, with two walk-in closets, a spacious bath, and direct access to the covered porch. At the same time, the secondary bedrooms are treated with real care rather than as smaller afterthoughts, which makes the home more comfortable for families and guests alike. The outdoor kitchen and fireplace complete the picture by making the lanai feel like a true living space instead of a decorative extra.<\/p>\n

For buyers looking for a one-story coastal home with upscale features, a thoughtful floor plan, and room to entertain both inside and out, this design checks a lot of boxes. It feels polished without being formal, spacious without being wasteful, and flexible enough to serve a household well for many years.<\/p>\n
