This two-story detached plan puts a 2-car garage (23'-0" × 16'-6") on the ground floor and a one-bedroom apartment above it. The footprint is 24'-11" × 26'-11", and the plan has 900 sq ft of living space, not counting the garage. At ground level, an entry foyer (6'-10" × 8'-0") leads to the stair (6'-8" × 8'-0"). A storage and workshop room (8'-8" × 8'-0") completes the level.
Upstairs, the stair arrives at a landing hall (13'-3" × 3'-7") that links the rooms. The living room (11'-3" × 12'-7") and kitchen (11'-3" × 7'-8") share the same width and form one open space. The bedroom (9'-4" × 11'-11") has a 3'-5" × 4'-6" closet. The bathroom (6'-2" × 8'-0") and a laundry closet (7'-6" × 4'-6") complete the apartment.

Who this plan suits
This plan suits owners who want a rental unit, guest suite or home office above a garage, or who need a small separate residence. It needs a lot that fits the 24'-11" × 26'-11" footprint plus driveway access to the garage and setbacks from the main house.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story detached garage apartment: ground floor 2-car garage and stair; upstairs 1 bedroom apartment with bath, open kitchen and living, laundry closet, about 600 sq ft of living space upstairs.” 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 1 bedroom garage apartment plans?
They describe a detached or attached building with a garage at ground level and a one-bedroom living unit above. This version has 900 sq ft of living space, one bath, and a 2-car garage that is not counted in that figure.
What affects the cost and lot requirements for this plan?
The 24'-11" × 26'-11" footprint sets the minimum lot area, and local setbacks, utility runs and driveway length add to it. Foundation type, finishes, and the need to run water, sewer and power to a separate building usually drive cost the most. Local zoning rules on accessory dwelling units also apply.
Can I change this plan by chat?
Yes. You can ask for changes such as different room sizes, the garage on another side, or a narrower or wider lot, and the plan is updated to match. Describe the change in plain language and review the revised layout before you download it.
How do I use the PDF, DXF and IFC files?
The PDF is for reading and sharing the drawings with a builder or permit office. The DXF opens in CAD software for 2D editing, and the IFC loads into BIM tools for 3D review. Local codes and engineering still need to be checked before construction.
