SPOKANE, Wash. -

Firefighters had their hands full on Saturday afternoon battling a large house fire on the lower South Hill.

The fire broke out around 2:45 p.m. at a house near Sixth and Adams.

When fire crews arrived on scene, massive flames and smoke were visible. Fire officials said the home is vacant and currently being remodeled.

Roughly 30 firefighters worked to put out the fire. The fire started on the second floor and quickly spread to the attic. Because of the age of the home, it was very tough for firefighters to put out the fire.

In older homes, there's typically no fire breaks so fire can travel fast and that's exactly what happened in this case.

"The whole top side was totally engulfed in flames. It was coming out the front there, it was really bad at first," Tamera Martello, who lives close by, said.

As of now, fire crews don't know what caused the fire.
