This tiny house plan fits a family of five into 810 square feet of living space on a single story. The footprint measures 26'-0" × 31'-0" and sits on a foundation, with no porch, deck or patio, so the structure stays compact and simple to frame.
You enter through a 12'-7" × 4'-9" mudroom with room for coats and shoes. The kitchen (12'-7" × 7'-10") opens to the living and dining area (11'-0" × 12'-11"). A hall leads to the 8'-0" × 5'-2" full bath, a 3'-6" × 5'-2" half bath, the parents' bedroom (11'-8" × 10'-2") and a bunk room (11'-11" × 10'-2") sized for three children. Two bedrooms, one and a half baths and no stairs keep daily routines on one level.
Layout highlights
- Mudroom entry, 12'-7" × 4'-9", gives the family a storage zone before the living space.
- Kitchen and living/dining share one open area for cooking, meals and play.
- Bunk room, 11'-11" × 10'-2", is sized for three children.
- Parents' bedroom, 11'-8" × 10'-2", sits beside the bunk room off the hall.
- Full bath plus a separate half bath reduce morning waits for seven-person-hour routines.

Who this plan suits
This plan suits a family of five that wants a small, single-level home with a separate bedroom for the parents and a shared bunk room for the children. It also fits buyers who want a simple rectangular footprint and a lower build size without giving up a full bath and a half bath.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house for a family of five on a 26 x 31 ft rectangular footprint (806 sq ft), one story, on a foundation: parents' bedroom, a bunk room for three children, 1 full bath and a half bath, open kitchen and living, mudroom entry with storage. 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
Can a family of five live comfortably in a tiny house?
It works when the plan separates sleeping, storage and shared space. This layout uses a bunk room for three children, a separate parents' bedroom, a mudroom for belongings and two bathrooms. Comfort still depends on how your family handles storage and daily routines.
How hard is this plan to build?
The 26'-0" × 31'-0" rectangular footprint on a foundation is a simple shape, with no porch, deck or patio to add. A local builder or engineer should review the plan against your site, climate and local code before construction.
Can I customize this plan with AI?
Yes. You can describe changes in plain language, such as a different bedroom arrangement, a larger kitchen or added storage, and the AI generates an updated layout. Check any revised plan against your site and local code requirements before you build.
Can I use the plan in CAD software with DXF files?
DXF is a common exchange format that most CAD programs can open, so you can refine the plan, add dimensions or share it with a designer or builder. Confirm the units and scale after import, and have a licensed professional review the drawings before permitting.
