This mother in law cottage plan is a single-level home with 690 sq ft of living space inside a 29'-6" × 25'-11" footprint. It has one bedroom, one accessible bath, a laundry room and a covered porch. There are no steps inside, and there is no garage.
The kitchen (10'-0" × 10'-11") and the living room (13'-7" × 11'-10") make up the open main area. A wide hall, 13'-7" × 4'-6", connects that area to the bedroom (10'-8" × 10'-11"), the laundry (5'-6" × 7'-8") and the accessible bath (7'-8" × 7'-8"). The bath is large enough for a roll-in shower, and the laundry sits close to the bedroom, so daily routines stay on one level.

Who this plan suits
This plan suits a parent or relative who wants a private home with no stairs and a bath they can use with a wheelchair or walker. It needs a lot that fits the 29'-6" × 25'-11" footprint plus setbacks and a path to the main house.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Accessible mother-in-law cottage: 1 bedroom, 1 accessible bath with roll-in shower, open kitchen and living, laundry, no steps, wide halls, covered porch, about 700 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 mother in law cottage plans?
Mother in law cottage plans describe a small, separate home built near a main house, usually for a relative. This version has one bedroom, one accessible bath, a kitchen, a living room and a laundry in 690 sq ft on one level.
What affects the lot and building cost of this plan?
The footprint is 29'-6" × 25'-11", so the lot must allow that size plus local setbacks, and utility connections to the main house or street affect site work. Cost also depends on foundation type, finishes, the roll-in shower, and local labor and material rates. Get a local builder quote for a firm number.
Can I change this plan by chat?
Yes. You can ask in chat to resize rooms, move the porch, add a garage on a chosen side, or adjust the layout for a narrower or wider lot. The plan is updated and you can review the new layout before you download.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan, sharing it and discussing it with a builder or local permit office. The DXF opens in CAD software for editing and drafting, and the IFC opens in BIM tools for 3D review. Local permits may still need stamped drawings from a licensed professional.
