Winds bring down partially built home in Sydney's west November 16, 2014 - 5:16PM 92 reading now Unusually strong winds across Sydney have contributed to the collapse of a partially constructed home in Sydney's west. Strong afternoon wind gusts peaked at about 80km/h at Sydney airport about 3pm. They reached a similar speed in Sydney's south-west about noon. Those gusts were enough to bring down a brick wall on a construction site in Merrylands, about 25 kilometres west of the Sydney CBD. The collapse of the wall in turn brought down the structural frame of the partially constructed duplex in Hilltop Road. The frame hit the house next door, which was left largely undamaged. Firefighters searched the rubble as a precaution but confirmed no one was injured. "There was no one on-site at the time," Superintendent Paul Johnstone of Fire and Rescue NSW said. There were very strong winds which contributed to the collapse but it's going to be investigated further by WorkCover NSW. The State Emergency Service said it has received about 190 calls for assistance across Sydney on Sunday and a further 90 around NSW. "Most of those have been for roof damage caused by falling branches," a spokeswoman said. Ben McBurney, a meteorologist at the Fairfax-owned Weatherzone service, said the winds were "just below damaging strength" of about 90km/h. Mr McBurney said the winds were brought by a low pressure system moving off the coast after bringing rain over the southern part of the state. Shortly before 5pm the Bureau of Meteorology cancelled a severe weather warning that had been issued for the Illawarra and central and southern tablelands, but not in Sydney. "Winds are expected to ease further this evening as a low-pressure system well off the NSW south coast moves steadily away," the bureau said in a bulletin.
