Brief it the way a visualiser gets briefed: typology and storey count first, then one or two materials, the site, the light, and the camera last. “Two-storey private house in board-formed concrete, cut into a steep grassy hillside so the upper floor cantilevers over the lower one, photographed at dusk from the slope below at eye level on a 35mm lens.” The storey count matters more than it looks. Leave it out and the model picks its own scale, so a “modern office building” comes back as anything from a three-floor box to a tower. Material is the other anchor. Board-formed concrete, charred timber, weathering steel, rammed earth and pale brick each bring their own detailing with them, and two is the practical limit before the facade turns into a sample board.
Then pair the light with the material, because that decides whether the surface reads at all. Low raking sun is for texture, which is why the brick warehouse below is lit from the side. Glass wants blue hour, when the sky is dim enough for lit floors to show through the reflections. Dark timber and anything in a forest look best under an overcast sky. For the camera, name one of three positions: eye level on a 28–35mm lens, a tilt-shift view with parallel verticals for anything tall, or an oblique drone view when the roof and the site are the story. All ten images below are unedited first outputs generated on BananaBanana, misses included: I asked for a two-storey steel addition on the warehouse and got one tall storey.
