Barndominium floor plans combine the spacious feel of a barn with modern home finishes, often at a lower cost per square foot than conventional construction. A two-story barndominium at 2,639 square feet offers three bedrooms, a bonus room, and a four-car garage with an RV bay. The layout uses an open-concept main level, stacked porches, and an upper-level wraparound sun deck for indoor-outdoor living. A 2 bedroom barndominium floor plan shows the barndominium concept adapted for compact family needs.
Open-Concept Main Level Design
The main level unites the living room, dining area, and kitchen in one volume. Eliminating interior walls between public zones makes the 2,639-square-foot plan feel larger. Large windows pull in natural light from multiple directions. Sliding glass doors lead to the stacked porch, creating a direct indoor-outdoor connection. This open-concept principle applies to other barndominium layouts, and barndominium 3 bedroom floor plans with loft spaces and outdoor patios shows how different rooflines affect interior volume.
Kitchen Layout and Storage
The kitchen features a central prep island with bar seating for three to four. The island serves as both a dining spot and meal prep staging area. A walk-in pantry provides dry storage, reducing upper cabinet clutter. The sink sits under a window facing the porch for a view while working. Countertops along two walls create an L-shaped work triangle with the island as the third point.
Sliding Glass Door Integration
Sliding glass doors between the living area and porch measure 8 to 10 feet wide, blurring the line between indoor and outdoor space. When fully open, the doors stack on one side for a clear passage. Furniture arrangements can extend from the living room onto the porch without a visual break. Screen panels on the exterior side of the track keep insects out while allowing airflow.
Primary Bedroom Suite Layout
The primary bedroom sits on the rear corner of the main level, separated from living areas by a short hallway. This keeps the bedroom quiet when the main living space is active. The bedroom measures 14 by 16 feet, enough for a king bed, side tables, and dresser. An ensuite bathroom connects directly to the bedroom, and a walk-in closet sits between the bath and entry.
| Primary Suite Component | Size | Key Feature |
|---|---|---|
| Bedroom | 14 x 16 ft | Separated from main living by hallway buffer |
| Walk-in closet | 6 x 8 ft | Double rod shelving, built-in drawers option |
| Ensuite bathroom | 8 x 10 ft | Double vanity, separate shower, water closet |
| Laundry room access | Adjacent | Direct access from hallway near primary suite |
The ensuite includes a double vanity, walk-in shower with bench, and a private water closet. A linen closet in the hallway provides towel and supply storage. The nearby laundry room makes the primary suite a self-contained zone.
Upper Level Bedrooms and Bonus Room
The upper floor holds two additional bedrooms and an oversized bonus room. The staircase rises from the main entry, keeping upstairs circulation separate from the main living zone. A hallway at the top distributes access to each room. The bonus room is the standout feature, with a wet bar and wraparound sun deck. Flexible upper-level layouts appear in barndominium floor plans with wraparound porches and lofts, where the second story maximizes views and outdoor access.
Bonus Room Wet Bar Configuration
The wet bar includes a small sink, under-counter refrigerator, and cabinet storage. A 4-foot counter with stools provides seating without encroaching on the main floor area. The wet bar needs a dedicated water supply line and drain from the main stack. Installing it along an interior wall near the bathroom plumbing chase reduces pipe runs. A 4.5 cubic foot mini-fridge fits under-counter dimensions.
Wraparound Sun Deck
The wraparound sun deck on the upper level extends living space outdoors. It wraps around the bonus room on two sides for seating, a small dining table, and plants. The deck uses composite boards with hidden fasteners for a clean look. Railings match the board and batten aesthetic with 2×2 balusters set 4 inches apart. Deck posts align with the main floor porch below, sharing footings to reduce foundation costs.
Exterior Style and Curb Appeal
The exterior uses board and batten siding with light wood accents at porch columns and gables. This creates the agricultural look of barn-style homes while keeping maintenance low. Stacked porches on the left add visual depth and covered outdoor space on both levels. A standing seam metal roof completes the exterior and sheds snow well in cold climates. The same exterior material strategy appears in barndominium designs with bold exteriors, where siding and roofing define the home’s character.
Siding and Trim Details
- Board and batten siding: 1×10 boards with 1×2 battens spaced 12 inches on center
- Trim at corners and windows: 1×4 primed wood or PVC trim for rot resistance
- Porch columns: Wrapped in light wood or cedar to contrast with the main siding
- Foundation apron: Painted or stained concrete to match the trim color
- Gable vents: Aluminum or wood louvered vents matched to siding color
The material list keeps the exterior budget predictable. Board and batten runs $4 to $8 per square foot installed, versus $8 to $15 for stone or $6 to $12 for brick. Metal roofing runs $7 to $12 per square foot versus $4 to $8 for asphalt, but lasts 40 to 60 years compared to 20 to 30.
Garage and Utility Configurations
The four-car garage includes an RV bay for recreational vehicles, boats, or workshop needs. The garage occupies much of the ground-level footprint with parking, storage, and mechanical space. A mechanical room inside the garage keeps the water heater, HVAC, and panel accessible without taking living space. Garage planning similar to this appears in 4 bedroom barndominium floor plans with lofts and wraparound porches, where the garage serves as vehicle storage and a workshop extension.
RV Bay Dimensions
An RV bay needs 12 feet minimum width and 14 feet height for most Class A and C motorhomes. Depth should be at least 40 feet for a standard RV with tow vehicle. The floor slopes toward a floor drain, and an exterior door at the rear provides backyard access. A 50-amp RV hookup with NEMA 14-50 outlet is installed for vehicle power. A hose bib and drain connection allow RV tank flushing without hoses across the driveway.
| Garage Feature | Specification | Purpose |
|---|---|---|
| Standard bays | 3 bays, 10 x 20 ft each | Daily vehicle parking |
| RV bay | 14 x 45 ft | RV or boat storage |
| Floor drain | Center of RV bay | Washdown drainage |
| 50-amp outlet | NEMA 14-50R | RV shore power |
| Mechanical room | 8 x 10 ft | HVAC, water heater, panel |
Standard bays hold two cars side by side plus one bay for workshop or storage. Overhead racks in standard bays hold kayaks, camping gear, or decorations. Insulating garage walls with R-13 and the ceiling with R-30 keeps the space usable year-round.
This barndominium floor plan delivers the open living spaces and flexible garages that make the style popular. Stacked porches, a bonus room with wet bar, and an RV bay offer features found in larger custom homes while keeping square footage under 2,700. For wide lots or different bedroom needs, a 3 bedroom barndominium floor plan designed for wide lots provides a one-story alternative with similar open living principles.
