A 3,594-square-foot duplex designed as a single-story country craftsman delivers two complete living units under one roof. Each unit contains two bedrooms, one kitchen, one family room, and a private courtyard, making this plan suitable for extended families, multigenerational households, or property owners who want rental income without managing separate buildings. This country style duplex floor plan wraps the living spaces around central courtyards that provide natural light and outdoor access from both wings.
Dual-Wing Layout: How the Two Units Are Organized
The house splits into two mirrored wings connected by a central courtyard element. Each wing measures roughly 1,797 square feet and operates as a self-contained home with its own entrance, living spaces, bedrooms, and mechanical systems. This arrangement differs from a typical side-by-side duplex where units share a common wall for their full depth. The dual-wing approach places the units at an angle or offset from one another so that each has three exterior exposures rather than just two. The single-story floor plan eliminates stairs, which makes the design accessible for aging family members or residents with mobility concerns.
| Feature | Unit A | Unit B |
|---|---|---|
| Bedrooms | 2 | 2 |
| Bathrooms | 2 | 2 |
| Square Footage | ~1,797 sq ft | ~1,797 sq ft |
| Courtyard | Private, east-facing | Private, west-facing |
| Garage | 2-car shared | 2-car shared |
| Covered Porch | Yes, front entry | Yes, front entry |
Interior Room Configuration Per Unit
Each unit in this country style duplex follows an open-concept layout centered on a combined kitchen and family room area. The owner’s suite sits at the rear of each wing, opposite the courtyard, which places the bedroom in the quietest part of the house. The second bedroom and the second bathroom sit near the front entrance, making them accessible to guests without disrupting the main living zone. A well-planned country craftsman house plan uses this separation to give each occupant clear territory within the shared structure.
Kitchen and Family Room Dimensions
The kitchen in each unit measures approximately 14 by 12 feet with an island that doubles as a breakfast bar. The family room adjoins the kitchen without a wall, creating a combined great room that spans roughly 500 square feet. Ceiling heights in these main living areas range from 9 to 10 feet, which improves the sense of spaciousness in a single-story structure that cannot rely on a two-story volume for drama.
Courtyards as Central Design Elements
Two private courtyards sit between the wings of the house, each one belonging to a specific unit. These outdoor rooms replace the side yards that a conventional single-family house would have. Each courtyard measures approximately 20 by 16 feet, providing 320 square feet of private outdoor space. The courtyards serve three distinct functions:
- They bring natural light into the interior through windows and sliding glass doors that face the courtyard rather than the neighboring unit
- They create a visual and acoustic buffer between the two wings, reducing sound transmission between units
- They function as outdoor living rooms for dining, gardening, or relaxation without requiring residents to share space
Courtyard Construction Details
A well-constructed courtyard requires proper drainage and surface treatment. The floor of the courtyard should slope at 1/4 inch per foot away from the building walls to direct rainwater toward a central drain or perimeter swale. Permeable pavers, concrete with a broom finish, or flagstone set on a gravel base are common surface choices. A minimum 4-inch concrete base under the pavers prevents settling and weed growth. The desert modern floor plan approach to courtyard design emphasizes shade structures and drought-tolerant planting, which can be adapted to this country craftsman style by using a pergola with climbing vines.
Country Craftsman Exterior Features
The exterior uses board-and-batten siding as the dominant cladding material. This vertical siding pattern, with boards placed 6 to 8 inches apart covered by narrow battens, creates a strong shadow line that adds texture to the facade. The four-car garage, split into two two-car sections for each unit, is integrated into the front elevation through matching siding and roof details rather than projecting as a separate mass.
Gable Accents and Roofline
Double-gabled roofs define the silhouette of each wing. The gables face the front of the property and are framed with exposed rafter tails, a signature craftsman detail. Roof pitch in country craftsman designs typically falls between 8:12 and 10:12, which provides enough slope for attic ventilation and snow shedding while maintaining the low, grounded profile characteristic of the style. Asphalt shingles in a dark charcoal or weathered wood color complete the roof. The front porch columns use a tapered profile that is wider at the base than at the top, resting on stone or brick piers that match the foundation cladding. This visual weight at the base anchors the elevation and gives the facade a sense of permanence.
| Exterior Element | Specification | Typical Cost Range |
|---|---|---|
| Siding | Board-and-batten, fiber-cement | $8 to $14 per sq ft installed |
| Roofing | Architectural asphalt shingles | $4 to $7 per sq ft installed |
| Porch Columns | Tapered craftsman style, painted | $400 to $800 per column |
| Garage Doors | Carriage-house style, insulated | $1,500 to $3,000 each |
Four-Car Garage and Site Integration
The four-car garage spans roughly 40 by 24 feet, providing 960 square feet of covered parking and storage. Each unit gets two garage bays, though the garage can be configured as a single continuous structure or as two separate garages with a breezeway between them. The breezeway option adds architectural interest and creates a covered walkway between the parking area and the courtyard entrances. In the single-structure configuration, a fire-rated wall with a 1-hour rating must separate the two garage sections to meet code requirements for attached garage spaces serving separate dwelling units.
Placement on the Lot
This duplex requires a lot with enough width to accommodate the dual-wing layout plus the garages. A minimum lot width of 80 feet is recommended, with 100 feet preferred for comfortable spacing between the structure and property lines. The open concept floor plan approach used inside each unit relies on the courtyard windows for daylight, so the building orientation on the lot needs to consider which direction the courtyards face to maximize sun exposure in winter and provide shade in summer.
Multigenerational Living Applications
A single-story duplex of this type works well for multigenerational households because each unit operates independently while sharing the same property. Typical scenarios include aging parents living in one wing while their adult children occupy the other, or two siblings sharing a property purchase to split costs. Common features that make this arrangement viable include:
- Separate utility meters so each unit pays its own electricity and water bills
- Individual HVAC systems with dedicated thermostats and ductwork
- Separate mailboxes and doorbells at each entrance
- Sound-rated interior wall assemblies between the two wings for privacy
Sound Attenuation Between Wings
The courtyard separation provides a natural sound barrier between units, but the mechanical systems, ductwork, and plumbing risers still require careful design to prevent noise transfer. Staggered stud wall construction with resilient channels and double layers of 5/8-inch drywall on the shared wall between a utility room and a living area achieves a Sound Transmission Class (STC) rating of 55 or higher, which blocks normal conversation entirely.
Plumbing and Electrical Separation
Each unit needs its own water heater, electrical panel, and plumbing stack. Placing these utilities in a shared utility closet that opens to the exterior rather than into either unit simplifies maintenance access and eliminates the need for one resident to grant the other access for repairs. A 50-gallon electric water heater serves the two-bedroom unit comfortably, while a 40-gallon unit handles the demand of the second unit if both have similar occupancy. Separate gas meters are required if the units use natural gas for heating or cooking. Local building codes typically mandate that each dwelling unit have its own disconnect switch and meter, so the electrical design must account for two meter sockets on the exterior wall, clearly labeled by unit.
Construction Costs and Budget Planning
Building a 3,594-square-foot duplex as a single structure costs less per square foot than building two separate houses of the same total square footage. Shared foundation walls, a common roof structure, and a single site development permit reduce overhead. Typical construction costs for this type of project break down as follows:
| Cost Category | Estimated Amount | Percentage of Total |
|---|---|---|
| Foundation and site work | $30,000 to $45,000 | 8% to 10% |
| Framing and roof structure | $72,000 to $108,000 | 20% to 25% |
| Exterior finishes (siding, roofing, windows) | $54,000 to $72,000 | 14% to 18% |
| Interior finishes per unit | $36,000 to $54,000 each | 20% to 25% |
| Mechanical systems (HVAC, plumbing, electrical) | $40,000 to $60,000 | 10% to 15% |
A country style duplex with this floor plan and layout brings together the independence of separate homes with the efficiency of shared construction. The dual-wing arrangement around private courtyards solves the privacy and noise issues that plague conventional attached housing while keeping the entire project under one roof. Property owners evaluating this design should focus on the courtyard drainage plan, the sound-rated wall assemblies between wings, and the separate metering requirements that make the duplex function as two independent residences. The open living with country style design approach ensures each unit feels spacious despite the shared structure, giving residents their own private outdoor space and a clear separation from their neighbors on the property.
