What you will make

A concept-image prompt, a geometry checklist, and an optional labeled PNG if an approved image interface is available.

Concept illustrations can help people discuss a design idea. Their usefulness depends on clear labels and honest spatial limits. A visually persuasive image can still change a building footprint, move a street, or show features that the brief never authorized.

• Describe a concept's view, design features, geometry, and visual style.
• Distinguish a blank background from actual transparent pixels.
• Check an image against its reference and label its conceptual status.

Work through the method

1. Record the reference

   Use an authorized sketch or written brief. List fixed footprint, street, opening, and placement geometry. Mark missing dimensions unknown; an unmeasured sketch is not survey evidence.

   Check your work: Known geometry and unspecified details are distinguished.

2. Write the visual brief

   Request a wide landscape architecture illustration with restrained pen lines and light color washes. Name the view, permitted additions, and either a plain white or transparent background.

   Check your work: Style, view, changes, and background are explicit.

3. Constrain spatial changes

   Require consistency with every fixed reference element. Omit unsupported site details. Use authoritative GIS separately when actual parcel lines, contours, or measured distances are needed.

   Check your work: The brief does not authorize a fabricated GIS map.

4. Compare any generated output

   If you generate an optional image, compare it with the sketch. Check proportions, street location, openings, and additions. Record discrepancies and revise or reject the image.

   Check your work: Each fixed element has an actual comparison check.

5. Verify the background

   For transparent PNG output, inspect the alpha/transparency channel and background pixels. Test over light and dark fills. White pixels or a painted checkerboard do not prove transparency.

   Check your work: Actual alpha inspection is recorded, or marked unperformed.

6. Label and package the concept

   Add a separate concept caption naming the reference and checks. Save the prompt and verification note. Include any PNG only after checking geometry and background.

   Check your work: The package labels concept status and completed checks.

Prompts to adapt

Replace the bracketed details with your own question and authorized source material. Check the output rather than treating it as evidence.

Using only [authorized reference sketch] and [written design brief], create a wide landscape architecture concept illustration with restrained pen lines and light color washes. Preserve these fixed elements: [footprint outline, street alignment, openings, and relative placement]. Add only [permitted concept additions]. Leave unspecified site details absent. Use a genuinely transparent background suitable for PNG export, not a white fill or painted checkerboard. Do not add parcel lines, contours, inferred hazards, dimensions, or existing-condition claims. The accompanying caption will identify the image as a concept illustration.

Use the same authorized reference and fixed-geometry list to create a restrained landscape architecture concept illustration on a plain white background. Preserve the stated footprint, street alignment, and openings. Add only the named concept changes. Do not create a site map or imply existing conditions. Do not claim the white background is transparent.

Prepare a bounded concept-illustration brief

1. List fixed reference geometry and unknown details.
2. Write a landscape architecture concept prompt with a blank or transparent background choice.
3. If you generate an optional image, compare it with the reference and inspect actual alpha when transparency is requested.
4. Save the prompt, checks, and concept caption; record checks not performed.

Bring the method into a product

• Prompt and geometry/background checklist
• Optional PNG concept with a separate caption

Suggested formats: TXT, PDF, PNG.

Reflect: Which visual detail could make a concept look like documented existing conditions?

Avoid these mistakes

• Generated imagery must not substitute for measured GIS maps.
• A checkerboard drawn into pixels is not a transparent background.
• A prompt requesting preserved geometry does not prove the output preserved it.
