He was head of construction supervision in the consortium Hall Todd & Littlemore appointed by the NSW Government Architect to complete the Sydney Opera House in April 1966 [1] when Mr Jørn Utzon resigned his commission from the NSW Government.
Peter Hall was design architect and Lionel Todd was responsible for contract documentation.
In New Guinea in the 1950s he built aircraft maintenance hangars by stringing cables between trees and suspending roofs from them.
Littlemore served for 10 years on the Council of Macquarie University and was made an officer of the Order of Australia in 1979.
