One, two or three bays
Ask for the bay count and the footprint you have to work with, and the plan lays the vehicles out inside it with the door openings in sensible places.
Garage Floor Plans From a Description
Say how many bays you need and what else has to fit — a workbench, a laundry run, a loft over the top — and get a plan image back with approximate dimensions. Attached, detached, tandem or drive-through.

Lay Out Your Garage
Describe the bays, the doors and what else has to fit.
Example prompt
Detached two-car garage, 24 by 24 ft, workbench along the back wall, side entry door and one window.
Sized around the vehicles, not around a template
A one-car garage is usually about 12 × 22 ft and a two-car about 24 × 24 ft — but the moment you add a workbench or a walk-around, those numbers stop working.
Attached or detached
An attached garage needs the connecting door, and usually a mudroom or laundry to land in. A detached one needs its own entry. Say which and the plan reflects it.
Room for the workbench
Workbenches, tool walls, shelving runs and a clear walk-around all take depth the bay dimension does not include. Name them in the description and they get their own space.
Laundry and mudroom off the bay
The strip between the garage and the house is prime space. Name the laundry, mudroom or storage wall in the description and it is drawn alongside the bays.
Check the footprint first
Lot coverage limits are written in square feet. Work the footprint out with the square footage calculator before you design to it.
How it works
Describe the garage
Bay count, overall footprint, attached or detached, and anything else that has to fit.
Generate
The description is wrapped in a 2D drafting prompt, so you get a plan with the bays and openings drawn rather than a rendering of a garage.
Refine it
Change the description and generate again — move the door opening, shift the workbench — then open the result full size.

Visit the Help CenterThe common footprint is 24 × 24 ft (about 7.3 m square); 20 × 20 ft is the tight minimum. Both assume parking only: a back-wall workbench adds about 3 ft of depth, and walk-around space between cars adds 2 to 4 ft of width.
A single door is typically 8 to 9 ft wide and a double door 16 ft. Height is usually 7 ft, or 8 ft where a roof box or taller vehicle must clear. Check the sizes your supplier stocks before you commit the opening.
They solve different problems. Attached is more convenient in bad weather and cheaper to run services to; detached keeps noise, fumes and fire risk away from the house and often suits an awkward lot. Local setback rules often decide for you.
Yes. Say the building is detached, give the footprint and the bay count, and name the workshop area — bench run, tool wall, clear floor space. You get a floor plan image; foundations, framing and elevations are outside what the tool draws.
You can lay out the garage level here and say where the stair goes. A habitable room above a garage is a second storey with its own structural, insulation and fire-separation requirements, and it often counts as an accessory dwelling unit, with different rules.
No. Treat the output as a layout study. Footings, framing, fire separation where a garage adjoins a house, lot coverage and setbacks must all be resolved against local code, and construction drawings need a licensed architect or engineer.
