IT took 11 fire crews to tackle a blaze at a shed in Wanneroo this afternoon.
The Department of Fire and Emergency Services crews remain at the property at the corner of Caporn and Honey streets to dampen down the area.
The fire units came from Wangara, Butler, Duncraig, Osborne Park and Joondalup stations.
A DFES spokeswoman said a Wanneroo Central Volunteer Bush Fire Brigade provided a big water tank.
A fire investigation analysis officer also attended.
