with designing the Callan Park grounds. From 1864 to 1905, Broughton House and nearby Kalouan (demolished in 1932) were the family homes of Sydney businessman John Keep. Keep lived there, extending it and purchasing adjoining land. After his death on 2 July 1905, his family sold the estate (the combined properties of Broughton Hall and Kalouan) to Annandale timber merchants William and Frederick Langdon in 1912. Convalescent hospital During World War I, the Langdons offered the site as a convalescent hospital for shell-shocked soldiers. The house and its expansive gardens were the perfect setting as a restorative home for soldiers. During the First World War changes to mental health care were instigated and in 1914 patients could only be treated if they were committed into one of the major institutions. Broughton Hall was resumed by the Government for repatriation care and this function became one of the main functions of Callan Park with additional facilities built in the grounds. Broughton Hall functioned as No. 13 Australian Army Hospital with the house and grounds used as a convalescent home for returned soldiers from the First World War, until 1921. A photograph of soldiers and nurses in the grounds was in "The Mirror of Australia" on 10 February 1918. During the early years of the 20th century health professionals pushed for early intervention in mental illness. Broughton Hall Psychiatric Clinic It was resumed by the government and on 4 April 1921 formally became the Broughton Hall Psychiatric Clinic. It opened as a voluntary admission clinic, NSW's first such. Through later years under Sydney Evan Jones, it became the largest such facility in Australia. The use of gardens was an integral part of the patients' treatment and paths, ponds and bridges were built throughout the grounds. Evan Jones redesigned Broughton Hall's gardens in the 1920s as a therapeutic environment for patients. New buildings of similar style and character, designed by the Government Architect, were added between 1920 and 1935. The part of Broughton Hall south of Church Street and east of Glover Street was redeveloped from 1956 to 1964. Government Architect Michael Dysart designed the Broughton Hall Psychiatric Clinic complex here. Dysart's modernist design was innovative in its day, built on the concept of architecture and landscape as components of therapeutic psychiatric care. Its modernist style is unusual in the wider context of Callan Park or Rozelle Hospital, much of which is Victorian
