A fire in west Edmonton that started in a house under construction and involved two more homes is now under control. 

Fire crews were first called to 154th Street and 99th Avenue at 6 p.m. Tuesday.

Ten minutes later, a second alarm was called after the fire spread to a house immediately south of the first home. The fire then spread north to a third structure. 

Laura Ruddock, a spokeswoman with Edmonton Fire Rescue, says the second structure sustained heavy damage. Six people were forced to leave that home and have not yet been allowed to return.

At least two people lived in the third house to catch fire. No one was injured. 

About fifty firefighters were called to the scene. Crews are expected to remain there into Wednesday morning. 

The cause of the fire is still under investigation.
