You can instantly finish ongoing construction and research in a village by spending Gold.
When a building upgrade or research task is already in progress, a Gold button appears. Selecting “complete construction immediately” opens a confirmation window. After confirming, all ongoing constructions and all research in that village finish instantly. The cost for instant completion is 2 Gold.
Keep in mind that this feature applies only to construction and research. It does not affect:
Celebrations
Buildings in the Master Builder queue
Troop training
Exceptions
For gameplay reasons, instant finish cannot be used on:
Residence
Palace
Command Center
World Wonder villages
The World Wonder itself
