Fire-fighters, Phaya Thai police and the Poh Teck Tung Foundation responded to calls and found the fire threatening a sizeable portion of the sprawling community. 
It took only about 30 minutes to bring under control, however. Twelve houses sustained damage. 
A police spokesperson said a forensics team would examine the house where the fire began to determine the cause.
