High above western Sydney, the NSW Building Commission is using satellites to understand why new homes in western Sydney are cracking and why the ground is collapsing.
Building Commissioner David Chandler is using the technology to try to understand why there is an epidemic of new homes cracking and sinking into the ground.
“You can go back and look at the subdivision when it was still a barn, and you can see the dips where there were dams and where the ground settled under the slab,” Chandler told 7NEWS.

A 7NEWS investigation last month uncovered a number of flooded suburbs across the city. From Glenmore Park to Box Hill, families reported problems such as cracks, hanging doors and walls coming off the ground.
Since then, the building commissioner has begun cracking down on suspicious foundations.
“I know the Building Commissioner, specifically, has looked at some of the subsidence issues in parts of western Sydney, and they’ve been alerted to that by 7NEWS,” NSW Premier Chris Minns said.
The commissioner has so far found problems ranging from minor subsidence to major flooding throughout the city. Jordan Springs remains the most notorious and notorious example.
“I think there are some Wild West players who maybe thought they could get away with things in the past that they couldn’t get away with in the future,” Chandler said.
The Prime Minister told 7NEWS that subsidence problems on flood-prone land in particular had prompted a rethink within government about where new homes should be built.
“We have made unpopular decisions, especially over the past six months regarding residential construction,” he said.
Residents who believe they have flooding issues on their property are urged to come forward.
“If construction workers come back three, four, five, even six times to fix cracks in good faith, something is wrong,” Chandler said.
“If a community member has concerns about subsidence on their property or in their community, I encourage them to contact the building commissioner,” Chris Means added.
