Six young people are helping police with the investigation into a "suspicious" fire that engulfed the abandoned Big Brother house on the Gold Coast.

Emergency services were called to the single-level building near Foxwell Road at Coomera just after 2pm on Saturday, with about four urban fire trucks and two rural trucks on scene.

"It appears to be a very large fire and rural truck appliances are there to supply more water," a Queensland Fire and Emergency Services spokeswoman said.

Police said the fire was not posing a risk to other property.
