Firefighters are continuing to use a defensive strategy to fight the blaze.
No other properties are under threat, the fire has been contained to the property but is not under control.
Due to extensive smoke logging in the cul-de-sac all residents were evacuated to a neighbouring street.
The Haz Mat crews are conducting atmospheric monitoring in all of the homes.
The ACT Ambulance Service is also in attendance. Intensive care paramedics have not treated anyone yet.
