This 20x24 tiny house plan places one bedroom and one bath on a single level, inside a 20'-0" × 24'-0" rectangular footprint built on a foundation. Living area is 480 sq ft, and there is no porch, deck or patio, so the full footprint is enclosed floor space.
The open living and dining room measures 12'-7" × 13'-3" and shares the floor with an 8'-0" × 8'-5" kitchen. The bedroom is 9'-8" × 8'-5". The bathroom measures 5'-1" × 8'-4", and a 5'-1" × 4'-6" laundry closet keeps laundry out of the main rooms. With one level and no stairs, the plan is easy to read, furnish and build. It suits a small lot as a primary home, guest house or rental unit.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house on a 20 x 24 ft rectangular footprint (480 sq ft), one story, on a foundation: 1 bedroom, 1 bath, open kitchen and living with a dining spot, 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 20x24 tiny house plan?
It is a house plan built on a rectangular footprint of 20 feet by 24 feet. This version is a single-story home with one bedroom, one bath, an open kitchen and living area, and a laundry closet.
Can this tiny house be built on a foundation?
Yes, the plan is drawn for a foundation build rather than a trailer. Foundation type, framing and energy requirements depend on your site and local code, so have a local engineer or building department review the plan before you build.
Can I customize this plan with AI?
Yes. You can describe changes in plain language, such as moving the laundry closet, resizing the bedroom or changing the kitchen layout, and generate an updated version. Check the new room sizes and any structural changes with a licensed professional before construction.
Can I use the plan in CAD software as a DXF file?
A DXF file opens in most CAD programs, so you can measure, edit and add your own notes or site details. Confirm units and scale after import, since settings can differ between programs.
