This 5,815 square foot mountain prairie house plan is designed for homeowners who want a large family home with rustic character, wide-open living areas, and a thoughtful layout that feels both impressive and practical. With 6 bedrooms, 5 full bathrooms, and an attached 3-car garage, the home offers enough space for a large household, visiting guests, multigenerational living, or flexible rooms that can change with the family over time.
The plan includes 5,350 square feet on the first floor and 465 square feet on the second floor. Most of the daily living space is located on the main level, which makes the home comfortable and convenient despite its large size. The upper-level space adds flexibility without turning the home into a traditional two-story design.
This home combines Craftsman, mountain, rustic, and vacation-style influences. It has the kind of warm architectural presence that works well on a wooded lot, prairie setting, mountain property, countryside acreage, or private retreat. The broad 91-foot width and 153-foot depth give the house a substantial footprint, allowing the rooms to spread out with privacy and breathing room.
Important lifestyle features include a courtyard-style arrival, clustered bedrooms, a first-floor primary suite with a sitting area, main-level laundry, a walk-in pantry, and a 1,058 square foot side-entry garage. These details make the design feel polished but still highly functional for everyday living.
Exterior and Curb Appeal
The exterior has a strong mountain prairie character with a broad one-level profile, multiple gables, rustic detailing, and a welcoming covered porch presence. The design feels grounded and substantial, which is important for a large home with this much square footage. Rather than relying on height alone, the house uses width, rooflines, materials, and outdoor transitions to create visual impact.
The Craftsman influence shows through the gabled roof forms, covered entry, and natural sense of proportion. The mountain and rustic elements give the home a relaxed lodge-like personality, while the prairie influence helps keep the design wide, low, and connected to the landscape.
The courtyard feature adds a memorable arrival experience. Instead of a plain front approach, the home creates a more private and defined entry zone. This can make the exterior feel more custom and inviting, especially when paired with landscaping, stonework, pavers, or low garden walls.
The home measures 91 feet wide by 153 feet deep, so it is best suited for a large lot. The depth of the plan allows for spacious interior zones and a comfortable separation between public rooms, bedroom areas, garage access, and private retreats.
The maximum ridge height is 35 feet, giving the roofline a strong architectural presence without making the home feel overly vertical. The attached 3-car garage is positioned with a side-entry orientation, helping the front elevation remain focused on the home’s architecture rather than garage doors.
Porch and Outdoor Living
Outdoor living is an important part of the home’s character. The covered porch and courtyard-style entry create a welcoming transition from the outside to the interior, while the large footprint gives the rear and side areas strong potential for patios, outdoor seating, gardens, or extended entertainment spaces.
A mountain prairie house plan works especially well when it has room to breathe. This design is not meant to feel squeezed onto a small lot. It is better suited for a property where the exterior can be viewed from multiple angles and where the porch, courtyard, and garage approach can be part of the overall landscape design.
The covered front area can be furnished with simple seating, planters, lanterns, or rustic accents to strengthen the home’s relaxed mountain character. It gives guests a sheltered place to arrive and gives the front elevation more depth.
The courtyard can also become a useful outdoor feature. Depending on the final site design, it could support a decorative garden, seating area, fountain, or landscaped arrival court. This gives the home a more refined sense of entry while still maintaining a warm and natural feel.
Because the home has generous depth, the rear yard could easily support outdoor dining, a fireplace patio, grilling area, pool, or covered terrace. The design gives homeowners a strong architectural base for creating a complete indoor-outdoor lifestyle around the house.
2D Floor Plan and Interior Layout
The 2D floor plan is organized with 5,350 square feet on the main level and 465 square feet on the second floor. This arrangement keeps most of the home’s function on one level while adding an upper-level bonus area for flexible use.
The main level is designed around a spacious family-focused layout. The floor plan includes a large great room, dining area, kitchen, walk-in pantry, clustered bedrooms, main-level laundry, a first-floor primary suite with a sitting area, and direct access to the attached 3-car garage.
The great room is one of the central gathering spaces in the home. It is large enough to support comfortable seating, a fireplace focal point, and everyday family use. Its location near the dining and kitchen areas helps create an open flow for entertaining and daily living.
The dining area is positioned close to both the great room and kitchen, which makes meals and gatherings easier to manage. This relationship between cooking, dining, and relaxing spaces is important in a large family home because it keeps the daily-use rooms connected instead of scattered.
The kitchen is designed as a major working space, with room for a central island and a large walk-in pantry nearby. The pantry supports storage for groceries, small appliances, serving items, and bulk household supplies. In a home with 6 bedrooms, this kind of pantry space is essential for keeping the kitchen organized.
The bedrooms are clustered in a way that keeps the sleeping areas organized while still supporting privacy. The first-floor primary suite includes a sitting area, giving the owners a quiet retreat within the home. Secondary bedrooms can serve children, guests, older family members, or flexible uses such as an office, hobby room, or study space.
The second floor adds 465 square feet of heated space. This upper-level area can function as a bonus room, studio, guest room, teen retreat, homework space, media room, or quiet getaway. Because it is separated from the main living areas, it gives the floor plan extra flexibility without interrupting the main-level layout.
Kitchen and Living Spaces
The kitchen and living spaces are designed for a household that needs room to gather, cook, host, and relax. In a 5,815 square foot house plan, the kitchen needs to do more than provide basic meal prep space. It needs to support a large family, frequent guests, holiday meals, and everyday traffic.
The kitchen’s connection to the dining area and great room gives the home an open and comfortable rhythm. Family members can move easily between cooking, eating, and relaxing, while guests can gather without feeling separated from the person preparing food.
The walk-in pantry is one of the most practical features in this part of the plan. It gives homeowners a dedicated place for food storage, serving pieces, small appliances, paper goods, and seasonal entertaining supplies. This keeps the main kitchen cleaner and allows the island and counters to remain more useful for daily tasks.
The great room is the heart of the home. Its generous scale makes it suitable for large furniture arrangements, conversation seating, a fireplace wall, built-ins, or a media area. For families who spend most of their time together in one central space, this room provides the comfort and size needed for daily life.
The dining area works as a bridge between the kitchen and great room. It can be casual enough for weeknight dinners but large enough to support holidays and special occasions. This kind of flexible dining arrangement is valuable because it allows the home to feel practical instead of overly formal.
The upper-level bonus space also expands the living potential. It can become a quieter area away from the main gathering spaces, which is useful for teenagers, guests, hobbies, or work-from-home needs. In a home with six bedrooms, having a separate flexible room helps prevent the main living areas from becoming overcrowded.
Bedrooms and Bathrooms
This house plan includes 6 bedrooms and 5 full bathrooms, making it well suited for a large family or homeowners who frequently host overnight guests. The bedroom count also gives the plan flexibility, since not every bedroom has to be used strictly as a sleeping room.
The primary suite is located on the first floor and includes a sitting area. This gives the owners a private place to relax, read, enjoy coffee, or unwind away from the main living spaces. A sitting area makes the suite feel more complete and comfortable, especially in a large luxury home.
The clustered bedroom arrangement keeps the sleeping areas grouped in a logical part of the floor plan. This can be helpful for families with children because bedrooms remain organized and easy to access. At the same time, the primary suite can still feel private because of its larger layout and retreat-style features.
Secondary bedrooms can serve a wide range of household needs. They can be used for children, guests, in-laws, a nursery, a home office, a craft room, or a study. With six bedrooms available, the home can adapt as family needs change over time.
The 5 full bathrooms provide strong support for a home of this size. Multiple bathrooms reduce morning congestion, make guest stays more comfortable, and help the home function better during gatherings. This is especially important in a large family house plan where several people may need to get ready at the same time.
The upper-level space can also support guest or family use depending on how it is finished and furnished. It could become a private suite-like retreat, a studio, or a quiet room for hobbies and creative work.
Laundry and Storage Areas
The main-level laundry room is an important practical feature. Since most of the home’s heated square footage is on the first floor, having laundry on the main level keeps daily chores convenient. This is especially useful in a 6-bedroom home where laundry needs can be significant.
The walk-in pantry adds valuable storage near the kitchen. It helps organize food, appliances, serving items, and household supplies. In a large family home, pantry storage can make a major difference in how smoothly the kitchen functions from day to day.
The attached 3-car garage includes 1,058 square feet of space. This gives homeowners room for vehicles as well as tools, storage cabinets, lawn equipment, bicycles, outdoor gear, and seasonal items. The side-entry orientation also helps protect the home’s curb appeal.
The courtyard and garage approach can also support practical arrival routines. With the right built-ins or interior planning near the garage entry, the home can include a useful drop zone for shoes, coats, backpacks, sports gear, and everyday bags.
The six-bedroom layout naturally adds storage flexibility as well. Extra bedrooms can be fitted with shelving, closet systems, desks, or hobby storage if they are not needed as sleeping spaces. This makes the home adaptable for changing family needs over many years.
Structure and Specifications
This mountain prairie house plan includes 5,815 square feet of total heated living area. The first floor provides 5,350 square feet, while the second floor adds 465 square feet. This gives the home the convenience of mostly one-level living with the added benefit of a separate upstairs bonus space.
The home includes 6 bedrooms and 5 full bathrooms. The attached garage holds 3 cars and includes 1,058 square feet of area. The garage uses a side-entry location, which helps create a cleaner and more attractive front elevation.
The standard foundation is crawl space. This type of foundation can work well in many regions, depending on soil conditions, drainage, climate, local code requirements, and builder preference. A local professional should always review the foundation choice for the specific homesite.
The exterior walls are specified as 2×6 construction. This wall type provides added wall depth compared with standard 2×4 construction, which can be useful for insulation, energy performance, and structural strength depending on the building location.
The overall dimensions are 91 feet wide by 153 feet deep. Because of the home’s large footprint and deep layout, it is best suited for a spacious lot with enough room for the house, side-entry garage, courtyard, driveway, outdoor living areas, and landscaping.
The first-floor ceiling height is 10 feet, while the second-floor ceiling height is 9 feet. These ceiling heights help the interior feel open, comfortable, and upscale. The maximum ridge height is 35 feet, giving the exterior a strong roof presence while maintaining the broad mountain prairie character.
Lifestyle and Cost
This house plan is a strong fit for homeowners who want a large rustic family home with flexible bedrooms, main-level living, and a comfortable connection to outdoor spaces. It works well for large families, multigenerational households, frequent hosts, or homeowners who want extra rooms for work, hobbies, guests, and recreation.
The courtyard entry gives the home a special sense of arrival, while the great room, dining area, kitchen, and pantry support daily family life. The first-floor primary suite with a sitting area creates a private owner’s retreat, and the second-floor bonus area adds flexibility for future needs.
The 3-car side-entry garage adds practical value for families with multiple vehicles or outdoor equipment. The large garage area also makes the home better suited for country, mountain, or acreage living, where storage needs are often greater than in a typical suburban home.
In the United States, a realistic construction cost for a home of this size and style may commonly range from about $1.15 million to $2.35 million or more. This broad estimate reflects the 5,815 square feet of heated living space, large footprint, 3-car garage, 2×6 exterior walls, crawl foundation, rustic Craftsman detailing, courtyard feature, multiple bedrooms and bathrooms, and overall finish quality.
The final cost can vary widely depending on region, labor rates, contractor availability, material prices, site preparation, foundation requirements, permits, utilities, roofing, windows, exterior finishes, cabinetry, flooring, appliances, and interior selections. A large one-level footprint can require more foundation and roof area than a compact two-story plan, which may increase the construction budget. Premium finishes, custom millwork, stonework, and high-end windows can also raise the final cost.
