A woman living in the house, who did not want to be named, said the fire began about 9.30pm in their recycling, but what started it was unknown at that stage.
On Christmas Eve, detectives were also at the scene of three scrub fires that scorched a dump truck on Carrick Rd, Twyford, the day before.
Fire crews also attended another grass fire on Ormond Rd, Twyford, shortly after.
A police spokesperson said inquiries were ongoing as to whether the scrub and grass fires were arson.
Meanwhile, an investigation into a house fire in Hastings in the early hours of Thursday morning has determined it was an electrical fire.
Emergency services were called to the fire in Wavell St, Akina, about 4.51am on Christmas Eve.
