Grey-box approval is not a shortcut. It is a contract that geometry, camera height, and field of view are correct before expensive surfacing work begins.

When it works

Competitions with fixed massing, repeat typologies, and a known context pack are ideal. The team can judge proportion and skyline in a day.

When it fails

Projects that still iterate façade depth or balcony rhythm need clay or simplified materials — otherwise “approve” means different things to different stakeholders.

Sign-off artifact

We deliver a short PDF: camera list, focal notes, and one still per view with dimension anchors. No textures, no planting — just decisions.
