A man was found dead inside the Walnut Crescent residence, while a woman managed to escape uninjured.
Ambulance officers assessed the female for the effects of smoke inhalation and minor injuries. However she declined transport to hospital.
Local media reported that the single-storey house was located within a gated complex and that its roof had completely collapsed by the time firefighters arrived on scene.
Police will prepare a report for the coroner.
They said on Saturday morning detectives had spoken to a female witness and that while investigations were continuing, initial information indicated the man's death was non-suspicious.
