Barndominiums have evolved from simple metal barn conversions into refined residential designs that blend agricultural roots with contemporary living standards. The two-story plan spanning 2,013 square feet featured on Home Stratosphere exemplifies this evolution, combining a crisp white exterior with a dark metal gable roof and an open interior defined by a two-story great room. This house plan design accommodates two bedrooms and two bathrooms while incorporating a loft, covered patio, and thoughtful storage solutions within a compact footprint that works well on rural or suburban lots.
What Defines a Modern Barndominium Design
A modern barndominium combines the open, flexible interior of a barn structure with the finishes and amenities of a conventional residence. Unlike traditional farmhouses that separate rooms with interior load-bearing walls, barndominiums typically use post-frame or steel-frame construction to create wide, column-free interior spaces. The exterior maintains agricultural references through metal roofing, board and batten siding, and simple gable forms, while interior finishes match or exceed those found in stick-built homes.
Key Structural Differences from Conventional Construction
Post-frame construction, the most common barndominium building method, uses heavy timber columns embedded in the ground or set on concrete piers, with trusses spanning between them at wider intervals than standard stick framing. This approach reduces the number of interior supports needed and allows for clear-span spaces up to 40 feet wide without load-bearing partitions. The 2,013 square foot plan takes advantage of this structural flexibility by placing the great room, kitchen, and dining area in an open configuration that spans the full depth of the main floor.
Steel versus Post-Frame Barndominium Construction
Steel-frame barndominiums offer the longest clear spans and the highest resistance to fire, termites, and rot, but they cost 10 to 20 percent more than post-frame equivalents and require specialized contractors for installation. Post-frame construction with treated lumber columns costs less upfront and is more readily available through local builders, though it may not achieve the same uninterrupted ceiling heights as steel. The choice between steel and post-frame also affects modern barn home insulation strategies, as post-frame walls typically use fiberglass batts between girts while steel frames require spray foam to prevent condensation on metal surfaces.
| Construction Method | Clear Span Maximum | Cost per Sq. Ft. | Construction Time | Insulation Method | Fire Rating |
|---|---|---|---|---|---|
| Post-frame (wood) | 30-40 ft | $80-$130 | 3-5 months | Fiberglass batts | Class B |
| Steel frame | 50-80 ft | $95-$160 | 4-7 months | Spray foam | Class A |
| Stick-built (conventional) | 16-24 ft | $120-$200 | 6-10 months | Fiberglass batts or blown-in | Class B |
| Insulated concrete forms | 20-30 ft | $140-$200 | 5-8 months | Built-in (ICF) | Class A |
Two-Story Floor Plan Configuration
The 2,013 square foot plan arranges living spaces across two levels, with the main floor dedicated to the great room, kitchen, dining, master bedroom, and utility spaces, while the upper level contains a loft and the second bedroom. This vertical separation creates distinct zones for daily activities and rest without requiring the square footage that a single-story layout of equivalent room count would demand. A typical single-story plan with two bedrooms and similar room sizes would need roughly 1,600 to 1,800 square feet on one level, whereas the two-story approach compresses the footprint to approximately 28 by 40 feet.
Main Floor Layout: Great Room, Kitchen, and Dining
The main floor opens directly from the covered entry into the great room, which rises two stories to the roofline. The kitchen occupies a corner of the open space with a peninsula or island that defines the boundary between cooking and dining zones without blocking sightlines. The dining area sits between the kitchen and the great room, positioned to take advantage of natural light from both the front windows and the rear patio doors. This tri-zoned arrangement allows three distinct activities to occur simultaneously without visual separation, making the main floor feel substantially larger than its actual 1,200 square feet.
The pantry in this plan provides 40 to 50 cubic feet of dry goods storage, accessed from the kitchen work zone rather than from a hallway or mudroom. Pantry placement directly off the kitchen reduces the distance traveled during meal preparation and keeps bulk food items out of the primary cabinetry. The mechanical room sits opposite the pantry, housing the HVAC equipment, water heater, and electrical panel in a centralized location that minimizes duct runs and wiring distances.
The Great Room with Two-Story Ceiling
A two-story great room creates dramatic vertical space that distinguishes barndominium interiors from standard tract-home layouts. The ceiling rises 18 to 20 feet from floor to ridge, with windows on the upper portion of the walls admitting daylight deep into the floor plan. This volume allows for oversized windows or a wall of glass on the rear elevation, connecting the interior to the covered patio and surrounding landscape.
Acoustic and Thermal Performance in Tall Spaces
Two-story rooms present acoustic challenges because sound reflects off hard surfaces over longer distances before dissipating. Hardwood or tile floors in the great room amplify this effect, making area rugs, upholstered furniture, and acoustic panels practical additions. Window placement on the upper wall improves natural ventilation through the stack effect, where warm air rises and exits through operable clerestory windows while cooler air enters at ground level. This passive ventilation strategy reduces mechanical cooling loads by 10 to 15 percent during moderate weather months.
Window Placement Strategies for Two-Story Walls
Windows on a two-story wall require careful coordination between structural engineering and architectural intent. Full-height windows that extend from the main floor to the upper ceiling need engineered lintels or a structural header spanning the entire opening width. A more practical approach places a band of transom windows near the ceiling peak while maintaining a standard 6-foot-8-inch door or window wall on the main floor below. This split-window strategy delivers abundant natural light and the open-air feel of a two-story space while keeping glazing costs manageable and maintaining wall strength. The open layout mixed material design of this barndominium plan uses a combination of fixed casement windows on the upper wall and sliding glass doors at the main level to balance light, ventilation, and budget.
| Window Configuration | Natural Light Level | Installed Cost per Opening | Ventilation Potential | Structural Impact |
|---|---|---|---|---|
| Full-height window wall | High | $3,500-$6,000 | Moderate | Requires steel header |
| Transom band at ceiling | Medium-High | $1,200-$2,000 | Low (fixed often) | Standard framing |
| Clerestory strip windows | Medium | $800-$1,500 | High (operable) | Standard framing |
| Standard 3×5 windows | Medium-Low | $500-$900 | Moderate | Standard framing |
Main Floor Master Suite and Covered Patio Access
The master bedroom sits on the main floor at the rear of the home, positioned for direct access to the covered patio through a sliding glass door. This ground-floor placement suits homeowners who prefer single-level sleeping arrangements while still enjoying the vertical drama of the two-story great room. The master suite includes a walk-in closet and an ensuite bathroom with a shower, vanity, and water closet.
Covered Patio as an Outdoor Extension
The covered patio extends 12 to 14 feet from the rear facade, providing sheltered outdoor living space that connects directly to both the great room and the master bedroom. Stone pillars support the patio roof at the outer edge, creating a defined outdoor room that remains usable during light rain and direct sun. The patio floor typically uses stamped concrete, stone pavers, or a stained concrete finish that complements the home’s farmhouse aesthetic. A patio of this size adds roughly 180 to 200 square feet of usable living space without counting toward conditioned floor area.
The covered patio serves as the primary outdoor circulation space in this two-story barndominium plan. Unlike conventional homes where the backyard is accessed through a single door, the patio connects to both the great room and the master bedroom, creating multiple indoor-outdoor transitions that make the interior feel more expansive. This configuration works particularly well for modern barn homes situated on large rural lots where the outdoor living area becomes a focal point for entertaining and relaxation.
Upper Level Loft and Secondary Bedroom
The upper level of this barndominium plan contains a loft that overlooks the great room below, plus a second bedroom and a full bathroom. The loft functions as a flexible space that can serve as a home office, media room, play area, or additional seating for the great room. An open railing along the loft edge maintains visual connection between levels while meeting building code requirements for guard height, typically 36 inches for residential applications.
Loft Design Considerations and Building Code Requirements
Lofts in two-story homes must comply with International Residential Code requirements for emergency escape and rescue openings. If the loft contains a habitable room, it needs an operable window with a minimum opening area of 5.7 square feet and a sill height no more than 44 inches above the floor. The loft in the 2,013 square foot plan is designed as a secondary living space rather than a bedroom, which provides flexibility in egress requirements while still offering a functional upper-level room.
Staircase design for loft access requires a minimum width of 36 inches with tread depths of at least 10 inches and riser heights no greater than 7.75 inches. The stair landing at the bottom should extend at least 36 inches in the direction of travel. These dimensions ensure comfortable daily use while meeting code minimums. Barndominium floor plan layouts often integrate the staircase into the great room volume as a design feature, using open-riser treads and cable railings to maintain sightlines through the space.
Rural and Suburban Site Planning for Barndominiums
Barndominiums are increasingly permitted in suburban subdivisions as zoning codes adapt to the popularity of the style. However, many subdivisions still enforce architectural review guidelines that restrict metal roofs, board and batten siding, or post-frame construction methods. Rural counties typically have fewer restrictions but may impose minimum lot sizes of 1 to 5 acres for dwellings without conventional foundations. Before purchasing a barndominium plan, verify that the local zoning ordinance allows the specific construction method and exterior materials proposed.
Utility connections pose another consideration for rural barndominium sites. Well and septic systems add $15,000 to $30,000 to the total project cost compared to municipal connections. Driveway length also affects cost, with gravel drives running $3 to $5 per linear foot and paved drives costing $8 to $12 per linear foot. These site-specific costs should be factored into the project budget alongside the structure itself. A thorough barndominium floor plan review during the pre-construction phase helps identify potential site issues before foundation work begins, saving time and money during the build.
