Augustus Gibbes improved the estate and acquired additional land by purchase and lease. In 1881, he sold Yarralumla for 40,000 pounds to Frederick Campbell, a descendant of Robert Campbell, to travel overseas. Frederick Campbell erected a new, three-storey, brick house on the site of the former Yarralumla homestead at the beginning of the 1890s. Campbell's house would later form the basis of what is now the Governor-General of Australia's official Canberra residence, known colloquially as "Yarralumla" or "Government House". Campbell also built the large wooden Yarralumla Woolshed nearby in 1904.
