This one-story barndominium plan fits 970 square feet of living space on a 24-foot-wide rectangle, with a covered porch added outside the main footprint. The overall footprint, porch included, measures 24'-0" × 45'-11". The living zone sits along one side: a 13'-3" × 17'-6" great room opens to a 7'-7" × 15'-3" kitchen with an island and an 8'-5" × 11'-5" dining area, so cooking, eating and sitting share one long, open space.
The sleeping zone is grouped on the other side of a 7'-2" × 5'-10" hall. The 11'-8" × 10'-4" primary bedroom and the 10'-0" × 10'-4" second bedroom flank a shared 7'-9" × 5'-10" bathroom, and a 6'-4" × 5'-10" laundry opens from the same hall. Keeping the bedrooms, bath and laundry together shortens plumbing runs and leaves the open living area free of through traffic.

Who this plan suits
This plan suits a couple, a small household or a guest-house build that wants two bedrooms and an open main room in under 1,000 square feet. It needs a lot at least 24 feet wide plus setbacks, with about 46 feet of depth available for the house and covered porch.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Barndominium on a 24 x 40 ft rectangular footprint, one story: 2 bedrooms, 1 bath, open great room with kitchen island and dining, laundry, covered porch outside the rectangle, about 960 sq ft of living space.” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.
Frequently asked questions
What are 24x40 barndominium floor plans?
They are single-story, barn-style homes built on a rectangle about 24 feet wide and 40 feet long. The simple shape keeps framing and roofing straightforward. This version has 970 sq ft of living space, 2 bedrooms and 1 bath, with the covered porch outside the rectangle.
What affects the cost and lot needs of this plan?
The main drivers are foundation type, local labor, finishes, and utility connections for the one bathroom, kitchen and laundry. The grouped wet rooms help keep plumbing runs short. The overall footprint is 24'-0" × 45'-11", so check setbacks and septic or sewer locations on your lot.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as adding a bedroom, resizing the great room, moving the porch, or adapting the plan to a narrower or wider lot. The layout is regenerated so rooms still connect logically, and you can review the result before downloading.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with builders or neighbors. The DXF opens in CAD software for drafting and site layout. The IFC loads in BIM tools for coordination. Have a local engineer or designer verify the plan for your code and site before construction.
