City Mutual Life Assurance Building

The City Mutual Life Assurance Building is a ten-story office structure with polished granite and sandstone surfaces in downtown Sydney. Inside, there is a three-story high main business hall set at a 45-degree angle, along with two basement levels that run beneath the street.

After a design competition in 1934, architect Emil Sodersteen won the commission to build this structure, which opened on October 1, 1936. The project came during a time of economic change in Australia, with the building reflecting the growing ambitions of Sydney's business community.

The building shows how Sydney embraced American skyscraper ideas in the 1930s while keeping its own architectural character. You can see this mix in the polished stone surfaces and the way the entrance angles into the street corner, creating something that felt modern to people at that time.

The building sits on Hunter Street in the heart of the city and is easy to access while walking through the area. It was among the first Sydney structures with built-in air conditioning, making it a good stop when exploring early modern comfort features in office buildings.

The granite exterior displays detailed stone carvings and ornamental details that form a symmetrical pattern along the Hunter and Bligh Street facades. These hand-carved details are easy to miss, but they show the skill of the stone craftspeople who worked on finishing the building.
