None of the residents were affected by the crash, she said.
Chief executive Lesley Slieker said it was fortunate nobody was injured, because the front doors were next to where the car crashed and a bus stop was also right outside.
"For us I think the main thing is the mum and the two kids in the car were safe and there was no-one injured at the bus stop there."
The children, a baby boy about 8-months-old and a little girl aged about 3 were restrained in "good" carseats, Ms Slieker said.
"And they had airbags in their car as well."
The car caused about $10,000 worth of damage by pushing the outside wall about 5mm out of alignment and large double-glazed, eco-coated windows might need to be replaced.
