Another 14 people were pulled from under the rubble of the residential block in the city's densely populated Idi-Araba neighbourhood on Tuesday, with others feared trapped, rescue workers said.
Two people have died after a four-storey building collapsed in Lagos in southern Nigeria.
One male and one female were killed during the incident near to Lagos University Teaching Hospital in the country's largest city.
"There are about 14 people so far rescued alive. It was a four-storey building, fully residential. There are still some people trapped inside," Umo Okon, a Red Cross spokeswoman, said.
What caused the building to collapse was not immediately apparent, and the police are yet to comment.
Construction workers close by helped to remove the roof of the building to aid rescue attempts.
Poor quality materials used in construction and negligible building standards in Nigeria are often blamed for such collapses.
Buildings are often made with blocks of sand and cement scavenged from the ocean. Rain can subsequently cause degradation of these materials.
At least three people died in July 2008 when a four-storey shopping centre in Abuja, the capital, collapsed.
In 2006, 28 people were killed when another four-storey construction, with a restaurant, bar and shops, fell down in Lagos.
A residential four-storey building collapsed in , Nigeria on Tuesday. At least two people have died, and another fourteen people have been rescued from the debris.

The building was located in the Idi-Araba neighbourhood, a densely populated area of the city.

A spokeswoman for the Red Cross, Umo Okon, stated that "there are about 14 people so far rescued alive. It was a four-storey building, fully residential. There are still some people trapped inside."

Construction workers working at another site nearby helped remove the building's roof to help the rescue effort.

Building collapses are not unheard of in Nigeria: In 2006, 28 died after a building, with a restaurant and shops, collapsed in Lagos. In July of last year, three people were killed when another four-storey building came down in , the capital of the country.

It is still uncertain what caused the incident, although collapses such as these have in the past been blamed on poor building standards and low construction material quality.
