Cooinoo, in Kissing Point Road Turramurra, was built for William James Adams, the heir to the Tattersalls fortune. The house was featured as a private residence in
Our beautiful homes, N.S.W. originally published ca but soon afterwards became a genteel boarding house. It was described in The Home magazine in December 1931 as "the most notable guest house on the picturesque north shore line" where "for twenty-five years its hospitable doors [had] offered a welcome to those who demand a high standard of comfort in their daily lives". It was demolished for home units in the 1970s. [ref: Pauline Curby and Virginia Macleod
