Choose a layout

Pick the option you prefer. We will flag tight fits.

Technical assumptions

Concept renderings use a 9 ft interior ceiling and a standard flat-roof reference. Existing measurements stay separate.

Confirm doors, windows & visible conditions

Only mark conditions you can see or measure. Unknown structural and utility questions are intentionally deferred.

Existing plan referenceMagicPlan/Twindio or another existing plan remains the geometry reference.

No source-plan page has been loaded. This area intentionally does not draw a generic house or pretend to be to scale.

Confirm the garage perimeter, openings, attached wall, and orientation. Leave unknown positions unknown rather than accepting fabricated geometry.

Visible fixed-condition locations

Add wall/offset only when known from the scan, photo, or measurement.

Select a visible condition above to add a confirmation row.

Doors and windows

Use this only to correct or add openings that the scan/photo analysis missed.

No manual opening corrections added.

Approve the A3 proposed plan

The selected template and your program are used to generate A3. Treat this as the controlling 2D geometry for every later elevation, 3D camera view, and rendering.

A3 Proposed Garage Conversion Plan

After A3 is generated, choose another library layout or describe a change to the ADU Assistant and regenerate. Do not move on until the room/wall/opening geometry is right.
