🧱 Rapid City Block Prototype & Scale Test

Teams construct a low-fidelity prototype of one critical city system (energy grid, water management, housing cluster, or biodiversity corridor) using paper, cardboard, tape, and markers. They must apply a clear scale ratio (e.g., 1 cm = 10 m) and label key features tied to user needs and environmental legislation. Teams conduct a quick scale check and materials critique, documenting advantages and limitations of their chosen materials and representation choices.
