Twelve people were killed in an apartment-building collapse in Medellín, leading to new construction laws being passed in Colombia.

The collapse of the Space Building occurred on the night of October 12, 2013, when Tower 6 of the Space Building, a residential apartment complex, collapsed in Medellín, Colombia, killing 12 people. Local authorities evacuated the rest of the building to avoid an imminent new collapse. The cost of the building was more than $40.6 billion.
