Emergency services were searching for the missing workers, according to central government official Francisco Martin.
One of the injured workers was being treated at a hospital for a leg fracture, emergency services spokeswoman Beatriz Martin said.
Firefighters said that “several floors” of the five-storey building collapsed.
In video posted on X by emergency services, the building’s facade was covered with a huge green tarp typically used by construction crews when renovating older buildings.
The facade of the building was intact, and the rubble hadn’t fallen outside on the street. (AP)
