One of the tallest residential buildings in London was evacuated Wednesday morning after a water pipe burst on the top floor of Renaissance I, located across from Budweiser Gardens.

Emergency crews said people were trapped in their apartments on upper floors, unable to get down the hallway of the 28-storey building because the water was so high.

"Extensive areas of ceiling have collapsed on the 27th and 28th floors and water is running down through the entire building," said Assistant Deputy Fire Chief Shawn Fitzgerald.

He said power has been shut off to many units at Renaissance I, located at 71 King Street, and the elevators were down. Firefighters had to climb stairs to reach the troubled areas. 

Residents living on lower floors were allowed to return to their homes Wednesday afternoon. But people living on the 24th to 28th floors are still unable to return due to the location of the sprinkler system malfunction. 

Residents on the top 4 floors are waiting to hear from Tricar Group, the owners of the building, to find out when they can safely return home.

Tara Krajewski, marketing and communications specialist at Tricar said the building was undergoing routine monthly maintenance when the 28th floor sprinkler system standpipe failed, which led to the flooding. 

"This is an extremely rare and isolated incident, and we have immediately engaged restoration professionals to complete any cleanup or repairs necessary," said Krajewski.
