This detached ADU plan has 920 sq ft of living space on a single level, inside a footprint of 33'-10" × 29'-2". A porch marks the entry. The living room (15'-11" × 11'-7"), the dining area (9'-4" × 8'-0") and the kitchen with island (15'-8" × 8'-0") form one open zone, so cooking, eating and sitting share the same space.
A hall (5'-2" × 12'-3") leads from that open zone to the sleeping side. The primary bedroom (10'-0" × 10'-1") has its own ensuite bath (6'-0" × 8'-0"). Bedroom 2 (10'-0" × 8'-4") shares the hall with a second bathroom (6'-4" × 6'-0") and a laundry room (5'-2" × 6'-2"). Keeping the bedrooms apart from the main living room gives each occupant some privacy in a compact home.

Who this plan suits
This plan suits homeowners adding a rental, guest house or space for family in a backyard. It needs a lot with room for a 33'-10" × 29'-2" footprint plus the setbacks, utility access and separation from the main house that your local rules require.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Detached backyard ADU (accessory dwelling unit) with about 950 sq ft of living space: 2 bedrooms, 2 baths, open kitchen with island, dining and living, laundry, 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 950 sq ft ADU plans?
They are plans for an accessory dwelling unit of roughly this size, a small, self-contained home on the same lot as a main house. This version has 920 sq ft of living space on one level, with 2 bedrooms, 2 baths, a kitchen, a laundry room and a porch.
What affects the cost and lot requirements for this ADU?
The main drivers are the 33'-10" × 29'-2" footprint, site preparation, foundation type, and utility connections to the lot. Local setbacks, height limits and ADU size rules vary by city and county, so check them before you choose a location on your lot.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or moving rooms, adding a garage, choosing which side it sits on, or fitting a narrower lot. The plan is regenerated so the rooms still connect, and you can review the updated sizes.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the drawings. The DXF opens in CAD software for editing and drafting. The IFC loads into BIM tools for a 3D model. Local permit rules differ, so have a licensed professional review the plans before you submit them.
