An early morning fire destroyed a structure in Waianae today.

Eleven units with 36 firefighters responded to a 911 call of a structure fire at 86-138 E Kuwale Road shortly after 2:15 a.m. When fire crews arrived, they saw flames and smoke emanating from all sides of a single-story wooden building, the Honolulu Fire Department said.

Flames also scorched a large tree on the property.

There were no occupants in the building at the time of the blaze.

Firefighters brought the fire under control at 3:09 a.m. and extinguished it just before 4:30 a.m. No injuries were reported.

Fire investigators are looking into the cause of the fire. A damage estimate has yet to be determined.

Property records show the four-bedroom, two-bath home with a carport was built in 1972.

Investigators at the scene said the 1,152-square-foot residential structure was believed to be vacant.
