This 16x40 tiny house plan puts a single level on a 40'-0" × 16'-0" footprint. It has 590 sq ft of living space and a covered porch outside. The two bedrooms sit at opposite ends of the house, which keeps the sleeping areas apart. Bedroom 1 measures 9'-7" × 9'-5". Bedroom 2 measures 7'-0" × 14'-1".
Between the bedrooms, the kitchen (10'-9" × 8'-0") and the living room (8'-8" × 14'-1") share one open middle zone. Cooking, sitting and walking through the house use the same floor area, so no space goes to hallways. The bathroom (6'-10" × 5'-8") and the laundry closet (3'-7" × 5'-8") are compact service rooms that take up little of the plan. Living area excludes the porch.

Who this plan suits
This plan suits individuals, couples or small households who want two bedrooms in a compact single-level home, such as a guest house, rental unit or primary residence. It needs a lot that can take a long, narrow 40'-0" × 16'-0" footprint, with room for the covered porch.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house on a 16 x 40 ft footprint (640 sq ft): 2 small bedrooms at each end, 1 bath, open kitchen and living in the middle, laundry closet, covered porch.” 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 are 16x40 tiny house floor plans?
They are layouts built around a 16-foot by 40-foot rectangle. This version has 590 sq ft of living space on one level, with 2 bedrooms and 1 bath. The long, narrow shape puts a bedroom at each end and the shared living space in the middle.
What affects the lot and building cost for this plan?
The 40'-0" × 16'-0" footprint needs a lot with enough length, plus space for the covered porch and any setbacks. Cost depends mainly on your local labor and materials, foundation type, and finishes. The kitchen, bathroom and laundry closet are the most equipment-heavy rooms, so their fixtures and finishes can move the budget.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing a bedroom, moving the porch, adding a garage on a chosen side, or fitting a narrower or wider lot. The layout is regenerated with the new room sizes so you can review it before using it.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with a builder, contractor or permit office. The DXF opens in most CAD programs for editing lines and dimensions. The IFC is a BIM format you can import into compatible software to work with the model in 3D.
