A major fire in southeast Calgary destroyed two homes and severely damaged two others early Tuesday morning.

The fire started just after 2 a.m. in the 100 block of Auburn Bay Boulevard S.E.

All the affected residents were able to get out of their homes safely, officials said.

About 100 people were evacuated from nearby homes for a few hours while crews fought the blaze.

One of the evacuees, Jaques Botha, said the fire moved fast.

"We just saw the flames and they were two or three storeys high. It just destroyed everything quite quick," he said.

Using positive pressure ventilation, firefighters were able to save a fourth duplex, said Battalion Chief Al Magwood.

“By pressurizing the air it stops the spread of smoke and flames into the complex,” he said.

Crews needed to wait for a gas line to be shut off before all the hot spots could be fully extinguished.

An early estimate put the damage at $1 million. Four families have been displaced because of the damage to their homes.
