This small barndominium with garage plan puts 880 sq ft of living space on one level, inside a 45'-3" × 31'-6" footprint. A front porch leads into the living room, which measures 11'-9" × 20'-8" and sets the main axis of the house. The kitchen, at 13'-5" × 9'-0", sits beside it, so cooking, dining and sitting share one open zone.
The sleeping area is kept compact. A 5'-10" × 9'-5" hall serves the primary bedroom at 10'-6" × 10'-11", the second bedroom at 11'-3" × 8'-4", and the 5'-1" × 9'-5" bathroom. A 5'-9" × 9'-0" laundry room handles household chores. The attached 2-car garage, 18'-8" × 20'-2", sits under the same roof. Living square footage does not include the garage.

Who this plan suits

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Small barndominium with an attached 2-car garage under the same roof: 2 bedrooms, 1 bath, open kitchen and living, laundry, porch, about 1,000 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.

How do I use the PDF, DXF and IFC files?
The PDF is for review, sharing and permit discussions. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools for 3D coordination. Have a local engineer or designer check the plan against your site and code.
