Andersons was made Officer of the Order of Australia in 1983 for services to architecture and is a Life Fellow of the Australian Institute of Architects.
He did not accept this position when informed by the Minister for Public Works, Wal Murray, of the newly elected coalition government's intention to change the office to a small management agency.
In the late 1960s Andersons was responsible for the Captain Cook Wing of the Art Gallery of NSW[1] and Parramatta Court House and Police Station.
From 1984–1988, he led a team of architects and consultants on the upgrade of the public realm of Macquarie Street and Circular Quay, including the design of the Sydney Opera House forecourt and lower concourse.
[citation needed] At the same time he was involved with the initial planning of the Darling Harbour Project as well as writing the brief and superintending upon the design and construction of the Sydney Entertainment Centre (now demolished).
