This backyard cottage plan puts 600 square feet of living space on a single level, with one bedroom and one bath inside a 32'-2" × 22'-0" footprint. A deep front porch leads into the vaulted living room, which measures 11'-5" × 13'-5" and anchors the plan.
The kitchen, at 6'-7" × 11'-11", and the dining nook, at 7'-4" × 7'-8", share the open main space with the living room, so cooking, eating and sitting happen in one connected area. A 7'-6" × 3'-1" hall links that space to the private rooms: the 10'-8" × 10'-0" bedroom, the 5'-11" × 5'-5" bath and a 2'-9" × 3'-10" laundry closet. Keeping the bedroom and bath off a short hall separates sleeping from the daytime rooms without adding floor area.
Layout highlights
- Vaulted living room at 11'-5" × 13'-5" opens directly from the front porch.

- Laundry closet at 2'-9" × 3'-10" stays near the bedroom and bath.

Who this plan suits
This plan suits a homeowner adding a rental, guest house or small home for a family member behind an existing house. It needs a rear lot with room for a 32'-2" × 22'-0" footprint plus the front porch, setbacks and a path to the street.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Backyard cottage: 1 bedroom, 1 bath, open kitchen and living with vaulted feel, small dining spot, laundry closet, deep front porch, about 600 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 backyard cottage plans?
Backyard cottage plans describe a small detached home built behind a main house on the same lot. This one is a single-level, one-bedroom, one-bath design with 600 square feet of living space and no garage.
What affects the cost and lot requirements for this plan?
The 32'-2" × 22'-0" footprint, the vaulted living room roof and the utility connections to the main house are the main drivers. Local setbacks, maximum accessory dwelling unit size and permit rules vary, so check them with your jurisdiction before you build.
Can I change this plan by chat?
Yes. You can ask for changes in chat, such as moving or resizing rooms, adding a garage on a chosen side, 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 drafting and edits, and the IFC imports into BIM tools such as Revit or ArchiCAD. A local designer or engineer should check the plans against your site and code.
