This one-story barndominium plan provides 1,190 square feet of living space, with 2 bedrooms and 1 bath. The overall footprint measures 47'-11" × 30'-0" and includes a covered porch outside the main rectangle. The public side is open: a 21'-2" × 14'-8" great room sits beside a 10'-11" × 12'-11" kitchen with an island and a 9'-9" × 12'-11" dining area.
The private side is organized along a 5'-2" × 15'-8" hall. Bedroom 1 measures 10'-8" × 12'-3" and Bedroom 2 measures 10'-8" × 9'-9". The 10'-8" × 5'-2" bath, a 5'-2" × 7'-8" laundry and a 5'-2" × 3'-10" linen closet are all reached from the same hall. Bedrooms stay separate from the living area, and daily chores stay close to the sleeping rooms. There is no garage.

Who this plan suits
This plan suits a couple, a small household or a guest cabin that wants two bedrooms and open living without a garage. It needs a fairly level lot roughly 48 feet wide for the footprint, plus setbacks.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Barndominium on a 30 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 1,200 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 30x40 barndominium floor plans?
They are single-story, barn-style homes built on a compact rectangle of about 30 by 40 feet, often with an open living area and a simple roof. This version has 1,190 sq ft of living space, 2 bedrooms and 1 bath, with the covered porch placed outside the rectangle.
What affects the cost and lot needs of this plan?
The main drivers are the foundation type, local labor and material costs, the finish level of the kitchen and bath, and utility connections. The 47'-11" × 30'-0" footprint needs a lot wide enough for setbacks, and a level site keeps excavation and foundation work simpler.
Can I change this plan by chat?
Yes. You can ask to resize rooms, add or remove a bedroom, move the porch, add a garage on a chosen side, or fit the plan to a narrower or wider lot. The layout is regenerated so the rooms still connect, and you can review the updated sizes.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan with builders, lenders or neighbors. The DXF opens in CAD software for editing the 2D drawings, and the IFC loads into BIM tools for 3D coordination. Local codes and engineering requirements still need to be checked before construction.
