The siting or replacing of courts, gaols, police stations and other buildings around the state was also occurring at this time, following the establishment of "responsible government" from Perth. He also supervised and designed new buildings or additions for the established towns Albany and York, the port: Fremantle, the centre of government: Perth, and other parts of Western Australia. To meet the significantly increased population, post offices, schools, lighthouses and town halls were constructed in this period. Architectural reference was made to earlier colonial buildings, gracefully acknowledging the prior colonial architects, but existing ones were often removed to site the new plan. Large scale harbour, railway and other planning schemes were also realised during his time as "government architect", and these also required new buildings and structures.
