tiny home floor plans — dimensioned floor plan

This tiny home floor plan fits one bedroom, a flex room and one bath into 520 square feet of living space on a single story. The footprint is a simple 21'-0" × 25'-0" rectangle built on a foundation, with no porch, deck or patio, so the whole footprint is enclosed space.

The living room measures 9'-4" × 14'-11" and runs into the open kitchen at 9'-4" × 7'-9". The flex room, 9'-4" × 6'-8", works as an office or guest space. A short hall, 3'-7" × 7'-2", leads to the bathroom at 5'-5" × 7'-2" and the bedroom at 9'-4" × 8'-5". Four of the six rooms share a 9'-4" width, which keeps the layout compact and easy to read.

Layout highlights

  • Open kitchen and living room share one 9'-4" wide space.
  • Flex room at 9'-4" × 6'-8" serves as an office or guest nook.
  • Bedroom at 9'-4" × 8'-5" sits off a short hall.
  • Bathroom at 5'-5" × 7'-2" is placed beside the hall.
  • Rectangular 21'-0" × 25'-0" footprint on a foundation, with no porch or deck.

Who this plan suits

This plan suits a single person or couple who want a one-bedroom home with a separate room for work or visitors. It also fits anyone planning a compact primary residence, guest house or rental on a small lot.

How this plan was made

It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny home on a 21 x 25 ft rectangular footprint (525 sq ft), one story, on a foundation: 1 bedroom, a small flex room for an office or guests, 1 bath, open kitchen and living. 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 should I look for in tiny home floor plans?

Look for a simple footprint, an open kitchen and living area, and rooms that can serve more than one purpose. This plan uses a rectangle and a flex room to get one bedroom, one bath and shared living space into 520 square feet.

Can this tiny home be built on a foundation?

Yes, the plan is drawn as a one-story home on a foundation, not on wheels. Foundation type, structural design and local code requirements still need to be confirmed with a local engineer or building department before construction.

Can I customize this plan with AI?

Yes. You can describe changes in plain language, such as moving the bathroom, resizing the flex room or changing the kitchen layout, and the AI will generate an updated plan. Review the new room sizes and layout before you use it.

Can I get CAD or DXF files for this plan?

DXF files open in most CAD programs, so you can edit walls, rooms and dimensions or share the plan with a designer or builder. Check the dimensions in your CAD software before using the drawing for permits or construction.
