One of the region's oldest properties, Nudjia in Unanderra, has again changed hands, selling after auction on Saturday.In an interesting twist, the Cummins St property was purchased by one of the children of a previous owner.A crowd of about 40 people saw bidding peak at $645,000, but the listing agent, Martin, Morris and Jones, said a negotiated sale was reached after the auction.The agency's Daniel Hastings said the new owners had requested that the final sale price should not be disclosed.Nudjia, an Aboriginal name meaning "safe and protected place", was built around 1870 by William Warren Jenkins, son of the prominent shipping merchant Robert Jenkins, who received one of the first five land grants in the Illawarra, in 1817.It was built alongside a makeshift sandstone hut erected 20 years earlier.The home was badly in need of renovation when Illawarra-based builder Robert Adlington bought it for $760,000 in December 2006.Complete with red cedar features and a wraparound verandah, the whole weatherboard building was restored from top to bottom, to original condition.When sold in 2006 the home was on a 3000sqm block approved for subdivision. Two blocks have since been separated from its western edge, leaving the homestead on a 1976sqm lot.The historic home was last slated for private sale last year, with an asking price of $795,000.
