This one-story tiny house plan on a slab foundation offers 380 square feet of living space with one bedroom and one bathroom. The kitchen opens to the living area, so the main room reads as one continuous space, and a small utility closet keeps mechanicals and storage out of sight. There is no porch, deck, or patio, which keeps the footprint compact and the foundation simple.
The living area measures 9'-0" × 12'-3", and the kitchen runs 13'-11" × 5'-5" alongside it. The bedroom is 7'-8" × 6'-6", sized for a bed and compact storage. The bathroom is 7'-8" × 5'-5", and the utility closet is 2'-9" × 5'-5". Because the plan is a single level with no garage, it suits small lots, guest houses, and cabins built on a permanent slab.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house on a 19 x 20 ft rectangular footprint (380 sq ft), one story, on a foundation: slab foundation, 1 bedroom, 1 bath, kitchen open to the living area, utility 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 house plan on a foundation?
It is a small home designed to sit on a permanent foundation, rather than on a trailer chassis. This plan uses a slab foundation and provides 380 sq ft of living space on one level.
Can I build this plan myself?
A small single-story plan with a slab is simpler to build than a multi-level home, but it still needs site-specific work. Check local zoning, permits, and code requirements, and have the foundation and structural details reviewed by a local professional before construction.
How can I customize this plan with AI?
Describe the change you want, such as a different bedroom size, a moved bathroom, or a larger kitchen, and the AI generates an updated layout. You can review the result and keep adjusting until the room sizes and arrangement fit your needs.
Can I use the plan in CAD with a DXF file?
Yes. A DXF export opens in most CAD programs, so you can measure, annotate, and edit the floor plan. Confirm scale and units after import, and check dimensions against the room sizes listed on this page.
