This single-level, detached 1 bedroom ADU has 650 sq ft of living space on a 29'-2" × 25'-3" footprint. The open main area puts the 9'-4" × 11'-7" kitchen, with its island, beside a 14'-9" × 11'-3" living room, so cooking, dining and sitting share one space. The covered porch extends the living area outdoors.
A 7'-10" × 4'-5" hall separates the private rooms from the shared space. Along it sit a 3'-1" × 4'-5" stacked laundry and the 7'-0" × 5'-10" full bath. The 10'-1" × 11'-7" bedroom opens to a 7'-0" × 5'-5" walk-in closet, which keeps storage inside the bedroom and out of the living area. The plan has no garage, so the whole footprint is living space.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Detached 1 bedroom ADU for a backyard: bedroom with walk-in closet, full bath, open kitchen with island and living room, stacked laundry, covered porch, about 650 sq ft of living space.” 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

1 bedroom ADU plans describe an accessory dwelling unit with one separate bedroom, a bathroom, a kitchen and a living area. This one is detached and single-level, with 650 sq ft of living space, a full bath and a walk-in closet.
What affects the lot fit and cost of building this ADU?
The 29'-2" × 25'-3" footprint must fit within your setbacks, and your lot also needs a route for water, sewer and power. Cost depends on your local labor and material prices, foundation type, finishes and permit fees, so get a local contractor quote.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or moving rooms, adding a garage or switching its side, or fitting a narrower lot. The plan is then regenerated with the updated layout and room sizes.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan with a contractor or permit office. The DXF opens in CAD software for drafting edits, and the IFC imports into BIM tools. Local permits usually require review or stamping by a licensed professional.
