  "shape_and_silhouette": "A long low greenhouse rises from a dark basalt pressure base in three broad sawtooth roof steps toward the back.",
  "visual_description": "Each step's sloping face is one big pane of greenhouse-green glass in a heavy pressure-aluminum frame, glowing faintly from the tank rows inside; the steep face of each step is solid aluminum. Thick basalt end walls close both ends. One red airlock door opens in the front end wall, and two tall glass inspection panes break each long side. No sculpture: its luminous green roof, the largest green surface in the city, is its signature.",
