From massing to façade articulation with predictable lighting and material presets. This case study outlines the brief, constraints, workflow, prompt recipe, benchmarks, and key lessons for repeatable competition visuals.

• Iteration cadence: 3 versions with client notes incorporated.
• Time to first client-ready render: ~38s.
• Total iteration time saved: 6.1 hours (benchmarking method included).

A mid-rise residential block along a waterfront promenade needed fast concept visuals to communicate massing, rhythm, and evening ambience for a competition jury.

• Goal: compelling dusk imagery with legible unit rhythm and active ground floor.
• Context: pedestrian promenade, water edge, soft public lighting.
• Deliverables: 3 option sets showing façade/material variations.

• Height/mass: mid-rise volumes with step-backs on upper floors.
• Façade rhythm: bays and balcony cadence must read at jury distance.
• Ground floor: active frontage, canopy rhythm, warm interior glow.
• Lighting: dusk/blue-hour reflections without blown highlights.

1. Massing pass: white/clay mass with stepped terraces; set camera & horizon.
2. Façade pass: vary balcony depth, bay width, and vertical pilasters.
3. Material pass: option A (light stone + glass), B (warm timber + bronze), C (brick + metal).
4. Lighting pass: dusk base + warm interior highlights + gentle street fixtures.
5. Context pass: water plane with subtle ripples and reflections; sparse silhouettes.
6. Export: high-res for jury boards; medium-res for quick feedback.

Use this single prompt to generate the hero image:

waterfront mid-rise housing block at dusk, articulated façade rhythm (bays + balconies),
active ground floor with warm interior glow, soft street lighting, calm water reflections,
light stone and glass materials, subtle bronze accents, pedestrian promenade in foreground,
eye-level camera ~28–32mm, balanced composition, physically plausible lighting,
cinematic grading, high detail, 16:9 aspect ratio, print-ready

Optional negatives: no heavy traffic, no crowding, no blown highlights, no logos, no watermark.

• Time-to-first-render: ~38 seconds (typical).
• Option sets: three façade/material variations in < 12 minutes.
• Review quality: consistent camera & naming → faster jury feedback loops.
• Export: high-res PNG for boards; JPG for quick iterations.

• Keep balcony depth and bay width consistent within an option to clarify rhythm.
• Evening shots read best with warm interior glow and restrained street lighting.
• Exact dimensions and codes are out-of-scope here—use downstream CAD/BIM for compliance.
