This 750 sq ft ADU plan is a single-level detached backyard unit with a footprint of 34'-1" × 23'-7". The living room measures 17'-9" × 11'-7" and opens to the kitchen at 10'-4" × 9'-8", so cooking and sitting share one open space. A small porch marks the entry. There are no stairs and no garage, so all 750 sq ft is living space.
A hall measuring 11'-9" × 3'-7" connects the main living area to the rest of the rooms. Bedroom 1 is 13'-3" × 7'-8" and Bedroom 2 is 9'-4" × 9'-8". The bathroom, at 7'-10" × 5'-9", is shared by both bedrooms and by guests. The stacked laundry is a compact 3'-7" × 5'-9" room, which keeps washer and dryer out of the living space while using very little floor area.

Who this plan suits
This plan suits homeowners adding a rental, a guest house or space for a relative, and who want two bedrooms in a compact single-story unit. It needs a backyard that fits the 34'-1" × 23'-7" footprint plus the setbacks and utility access 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 750 sq ft of living space: 2 bedrooms, 1 bath, open kitchen and living, stacked laundry, small 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 750 sq ft ADU plans?
They are plans for an accessory dwelling unit with about 750 sq ft of living space, built as a separate home on the same lot as a main house. This version is a detached single-level unit with 2 bedrooms, 1 bath, an open kitchen and living area, and stacked laundry.
What affects the lot fit and building cost of this ADU?
The 34'-1" × 23'-7" footprint must fit within your setbacks, and your local ADU rules may limit size, height and placement. Cost depends mainly on site work, utility connections to the main house or street, foundation type, finishes and local labor rates, so get quotes from local builders.
Can I change this plan by chat?
Yes. You can ask for changes such as swapping or resizing rooms, moving the porch, adding a garage on a chosen side, or adjusting the footprint for a narrower or wider lot. The plan is regenerated with updated room sizes, so check the new measurements against your lot.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the layout and sharing it with family, a designer or a contractor. The DXF opens in common CAD programs for editing or site planning, and the IFC imports into BIM software. Local permits usually require drawings from a licensed professional in your area.
