This single-level detached ADU provides 1,000 square feet of living space on a 43'-8" × 24'-3" footprint. A front porch leads into the living room, which measures 15'-3" × 13'-3". The dining area (10'-5" × 8'-8") and the kitchen (7'-4" × 14'-9") sit alongside it, so cooking, eating and sitting share one open zone.
A hall (7'-2" × 7'-10") separates the bedrooms from the living area. The primary bedroom (10'-0" × 12'-11") has its own bath (5'-5" × 9'-0"). Bedroom 2 (11'-9" × 9'-0") is served by the hall bath (5'-2" × 8'-8"). The laundry room (7'-2" × 4'-9") keeps the washer and dryer out of the main living space.

Who this plan suits
This plan suits homeowners adding a rental, guest house or multigenerational home in a backyard, with two full baths and no stairs. It needs a lot with room for a 43'-8" × 24'-3" footprint plus the setbacks your local code requires.
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 1000 sq ft of living space: 2 bedrooms, 2 baths, open kitchen and living, dining, laundry room, 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 1000 sq ft ADU plans?
They are plans for an accessory dwelling unit with about 1,000 square feet of living space, built on the same lot as a main house. This version is a detached, single-level unit with 2 bedrooms, 2 baths, a kitchen, living room, dining area and laundry room.
What affects the lot and building cost of this ADU?
The main factors are local setbacks, maximum ADU size rules, utility connections to the main house, and site work such as grading and foundation type. The 43'-8" × 24'-3" footprint sets the minimum clear area you need. Get local quotes, since costs vary by region.
Can I change this plan by chat?
Yes. You can ask for changes such as moving or resizing rooms, switching the porch side, adding a garage, or fitting a narrower or wider lot. The layout is regenerated so the rooms still connect, and you can review the updated sizes before you download.
How do I use the PDF, DXF and IFC files?
The PDF is for review, sharing and permit discussions. The DXF opens in CAD tools for drafting and edits, and the IFC imports into BIM software for a 3D model. Have a local designer or engineer confirm the plans meet your site and code requirements.
