This tiny barndominium plan fits a one-story, one-bedroom home onto a 20'-0" × 30'-0" rectangular footprint, with 600 sq ft of living space on a foundation. The layout is a simple rectangle with no porch, deck or patio, which keeps the roofline and structure straightforward. It can serve as a guest house, studio, cabin or compact primary home.
The kitchen (7'-0" × 15'-7") and living room (10'-8" × 15'-7") share one open space of equal depth. The bedroom measures 9'-0" × 12'-1". The plan also includes a hall (3'-10" × 6'-2"), a laundry closet (4'-5" × 6'-2") and a bathroom (8'-8" × 5'-6"). With one bedroom and one bathroom, the program stays compact and focused on daily living. Every room is dimensioned, so you can check furniture fit before you build.
Layout highlights
- Single-story rectangle, 20'-0" × 30'-0", built on a foundation.
- Open kitchen and living room, 7'-0" and 10'-8" wide, both 15'-7" deep.
- Bedroom of 9'-0" × 12'-1" with its own place in the plan.
- Bathroom of 8'-8" × 5'-6" next to a 4'-5" × 6'-2" laundry closet.
- No porch, deck or patio, so the footprint stays a plain rectangle.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny barndominium on a 20 x 30 ft rectangular footprint (600 sq ft), one story, on a foundation: 1 bedroom, 1 bath, open kitchen and living, laundry closet. No porch, deck or patio.” 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 is a tiny barndominium?
A tiny barndominium is a small, barn-inspired home that combines living space in a simple rectangular building. This plan is one story with one bedroom and one bathroom, in a 20'-0" × 30'-0" footprint.
Can I build this plan on a foundation?
Yes. The plan is drawn as a one-story home on a foundation. Foundation type, framing, insulation and wall systems depend on your site, climate and local code, so have a local engineer or builder review the plan before permitting.
Can I customize this plan with AI?
Yes. You can describe changes in plain language, such as a different bedroom size or a moved laundry closet, and the layout is regenerated with updated room dimensions. Review any changed plan against local code before building.
Can I get CAD or DXF files for this plan?
DXF files let you open the plan in CAD software to measure, annotate or redraw it. They are a starting point for design work. Your builder or engineer should still confirm structural and code details for your site.
