Cullwalla and Terragong homesteads are both heritage-listed homesteads located east of Jamberoo on Jamberoo Road, built in 1858 by Marks brothers James Jr. and John respectively. The brothers had six siblings and their father was James Moody Marks, who came out from Ireland in 1828 with his wife and two oldest children (one of which was John). James Marks Sr. built the Steam Packet Inn (Kiama's second oldest inn) in Kiama in 1842.
James Marks built Cullwalla homestead in 1858. The homestead is a late Georgian house and is one of the oldest surviving buildings in the Kiama area, along with Terragong house and Minnamurra house - all at Jamberoo. The dairy farm has a worker's cottage, a dairy and a beautiful cultivated garden added during the 1860s. James married Sarah Jane Moffit and they had five children. (Both James Jr. and John married Moffitt sisters - daughters of William Moffitt, who was a Pitt Street bookseller and stationer.)
In 1911/12, two of James and Sarah's sons, Dr Herbert J W Marks and Walter Moffitt Marks, constructed a twelve-storey office block on the corner of King and Castlereagh streets in Sydney (Sydney's first 'skyscraper') in memory of their late mother from the proceeds of her estate. They named the building Cullwulla Chambers, after the family property, Cullwalla, at Jamberoo. At the time, at a height of 50m, it was the tallest building in Sydney.
