# B19 - Unnamed building

![Unnamed building](img/B19_x4.png)

`PLATEAU` tileset, **20 x 5 cells** (40 x 10 tiles of 8px, 320 x 80 px). Appears **1 time** in the game. Tile ids index `assets/generated/tilesets/plateau.png`, 16 per row.

Coordinates are 1-based and local to the building: cell x=1..20, y=1..5; tile column c=1..40, tile row r=1..10. No terrain padding is included - edge rows and columns that were pure ground have been trimmed.
