St Marys had been a Municipality for 40 years before an official home for council was built in Mamre Road. Finally in December 1933 the new building was opened. Designed by Sydney architect Mr Carfrea it was of semi-colonial style with a spacious council room with polished maple joinery and polished tallow wood floors. After the amalgamation of the local councils in 1949 the building became the St Marys Branch Library. In 1979 when the library moved to new premises, this building became the home of the St Marys Community Arts.“New Council Chambers Official Opening at St. Marys: A fine structure “, Nepean Times, 9 December 1933 p. 3.
