Resident Alistair Hayward said the fire was quite big, "surprisingly big".
The fire could be seen for miles.
The location of the blaze proved tricky for firefighters to get to, as it could only be accessed by a steep mountain pass - forcing firefighters battle the blaze from the road around 50m away, Hayward said.
"It was very close to quite a big patch of pine trees and it was touch and go whether those trees were going to go up in flames," he said.
Hayward said firefighters did a great job in containing the blaze, as a row of brand-new townhouses were under threat of being consumed by it.
