Authorities in Nigeria have started demolishing buildings near the site of the four-storey structure that collapsed on Wednesday in Lagos.
Local reports suggest that dozens of houses have been served with a demolition notice.
Omotayo Fakolujo, from the Lagos State Building Control Agency told the BBC that more than 100 buildings will be demolished on Lagos Island.
He added that a minimum of three will be demolished per day.
He also denied allegations that owners of marked buildings had paid bribes to avoid demolition.
At least 11 people died and 50 were rescued alive from the rubble of the collapsed building which housed a primary school in the Ita- Faji area of Lagos.
The search for more victims was brought to an end on Thursday.
The government says an investigation will be carried out and that anyone found guilty of wrongdoing would be prosecuted.
