This one-story casita provides 460 square feet of living space for one bedroom and one bath, with no garage. The footprint measures 25'-3" × 22'-4", compact enough to sit beside a main house or stand alone. The Sitting Room, at 12'-10" × 9'-0", is the central living space, and the Covered Courtyard Patio faces the courtyard for shaded outdoor seating.
The Kitchenette, at 6'-4" × 10'-11", is placed next to the sitting room, so cooking, eating, and relaxing share one zone. The Bedroom Suite, at 10'-1" × 10'-2", is grouped with the Bath (6'-0" × 4'-9") and the Walk-in Closet (6'-0" × 5'-1"). This keeps sleeping and dressing together and apart from daily living. Room sizes suit a guest, a relative, or a single resident.

This plan suits a guest house, in-law suite, or compact retreat for one person or a couple. It needs a lot with room for a 25'-3" × 22'-4" footprint plus a courtyard on the patio side.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Southwest casita: 1 bedroom suite with bath and walk-in closet, small kitchenette and sitting room, courtyard-facing covered patio, about 450 sq ft.” 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 casita floor plans?
Casita floor plans describe small, single-story dwellings, often in a Southwest style, with a bedroom, bath, and basic living space. This one has 460 square feet of living space, one bedroom, and one bath. It can serve as a guest house or a small primary residence.
What affects the lot and cost of building this casita?
The 25'-3" × 22'-4" footprint sets the minimum lot area, and the courtyard patio needs added space on its side. Cost depends on your region, foundation, finishes, and utility connections. The kitchenette and bath concentrate plumbing, which can keep utility runs short.
Can I change this casita plan by chat?
Yes. You can ask for changes in chat, such as resizing rooms, moving the patio to another side, adding a garage, or adjusting the plan for a narrower or wider lot. The layout is regenerated so the rooms still connect.
How do I use the PDF, DXF, and IFC files?
The PDF is for review, sharing, and permit discussions. The DXF opens in CAD software for editing and drafting, and the IFC imports into BIM tools such as Revit or ArchiCAD. Have a local engineer or architect check the plan against your site and code before building.
