Three people had a lucky escape in the early hours of Easter Friday morning after part of their south-west Sydney home collapsed.
Just after 4:30am on Friday, firefighters responded to reports a house, built only "six to 12 months" ago, had suffered structural damage on Norman Street in Condell Park.
When they arrived, they were confronted by a home with "significant damage collapse", particularly in one corner above the garage, according to Superintendent Adam Dewberry from Fire and Rescue NSW.
"Fortunately, there was a lucky escape with three people being able to self-evacuate with no injuries," Superintendent Dewberry said.
He sympathised with the family, which is spending Easter away from home.
"A terrorising event for them having to be evacuated at 4:30 in the morning; to be woken up by a loud bang and the house collapsing."
Fire crews which specialise in rescue and structural collapse attended the scene.
They carried out an assessment and created an exclusion zone.
Superintendent Dewberry said there was no indication of what caused the collapse, at this stage.
He did confirm the home was relatively new.
"I understand the home was new, six to 12 months old … Now we're not too sure how this occurred, but that'll be investigated by the relevant regulators."
NSW Better Regulation and Fair Trading Minister Anoulack Chanthivong called it a "shocking incident" that was a priority for his department.
"Fair Trading is investigating this situation," he said.
"Once the findings are finalised on how that has happened to this family, I'll work with the department and commissioner to ensure appropriate action is taken as a priority.
"Thankfully, no one was seriously harmed. I am also glad that the family were able to find temporary accommodation."
