This 14x40 tiny house plan fits a one-story, 2-bedroom, 1-bath home on a 14'-0" × 40'-0" rectangular footprint with 560 sq ft of living space. It is drawn for a foundation build and has no garage, porch, deck or patio, so the whole budget goes into enclosed floor area.
A bedroom sits at each end of the house. Bedroom 1 measures 6'-4" × 8'-4" and Bedroom 2 measures 7'-3" × 7'-4". Between them, the living room is 12'-0" × 12'-1" and the kitchen is 12'-0" × 9'-1", forming one open middle zone. The bathroom is 5'-3" × 8'-4", and a laundry closet of 4'-5" × 7'-4" keeps the washer and dryer out of the main rooms.
Layout highlights
- Bedrooms at opposite ends of the 40-foot length give the two sleepers separation.
- Open kitchen and living room in the middle, each 12'-0" wide.
- Living room measures 12'-0" × 12'-1"; kitchen measures 12'-0" × 9'-1".
- Full bathroom at 5'-3" × 8'-4" plus a separate 4'-5" × 7'-4" laundry closet.
- Simple 14'-0" × 40'-0" rectangle on a foundation, with no porch, deck or garage.

Who this plan suits
This plan suits couples, small families or owners who want a guest room or home office in a compact one-story home. It also works for anyone who prefers a plain rectangular footprint on a narrow lot.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house on a 14 x 40 ft rectangular footprint (560 sq ft), one story, on a foundation: 2 small bedrooms, one at each end, 1 bath, open kitchen and living in the middle, 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 makes a 14x40 tiny house plan a practical shape?
A 14-foot width keeps framing and roof spans simple, and the 40-foot length lets you place rooms in a line. In this plan, the bedrooms sit at the ends and the shared living space sits in the middle. The long, narrow footprint also fits many narrow lots.
Can this plan be built on a foundation?
Yes. It is drawn as a one-story home on a foundation, with 560 sq ft of living space. Foundation type, framing, insulation and code requirements depend on your site and local jurisdiction, so have a local engineer or builder review the plan before you build.
How can I customize this plan with AI?
You can describe changes in plain language, such as swapping the laundry closet for storage, resizing a bedroom or moving the kitchen. The AI then redraws the layout with updated room sizes. Review each result against your needs and local code before you build.
Can I use the plan in CAD software as a DXF file?
DXF is a common exchange format that opens in most CAD programs, so you can bring the floor plan into your own drawing tools. There you can add dimensions, notes, electrical and plumbing layers, or site details. Check layers and scale after import.
