Adelaide’s Brutalist heartbeat: The story behind the scene and the people who created it

South Australia’s architectural heritage is facing a reckoning this month as state planners review the future of the heritage-listed blocks surrounding Rundle Mall. While glass towers continue to rise across the CBD, the 1970s-era concrete monoliths that anchored the city’s post-war identity are now at the center of an intense debate regarding demolition versus adaptive reuse. For the historians and former firm partners tasked with documenting these sites, the story behind our skyline isn't about the coldness of concrete, but the experimental ambition of a generation determined to shake off Adelaide’s 'City of Churches' reputation.

From drawing boards to concrete monoliths

The aesthetic shift began in earnest with the construction of the Wakefield House on Wakefield Street in 1972. Architectural records from the South Australian branch of the Australian Institute of Architects indicate that firms like Hassell and Woods Bagot were not merely building offices, but crafting a civic statement. They chose exposed aggregate and raw, board-marked concrete to mirror the ruggedness of the Adelaide Hills, a stark departure from the limestone facades that had dominated the city since 1836. These architects envisioned a dense, vertical life for the CBD, moving away from the sprawling residential designs that had defined the post-war suburban boom.

Today, the preservation of the Adelaide Law Courts and the surrounding civic precinct remains a top priority for groups like the Heritage Adelaide Trust. Research conducted by local scholars shows that over 45% of the city’s mid-century stock has been modified or reclad in the last decade, often sacrificing the thermal mass properties that made these buildings surprisingly efficient for their time. The preservationists argue that these buildings represent the city's transition into a modern global centre, a period where Adelaide became a testing ground for daring, geometric shapes that prioritised public accessibility over private glass facades.

The price of progress

Conservation experts suggest that retrofitting these structures is becoming an economically sound alternative to clearing the sites. Recent data from the Property Council of Australia indicates that refurbishment costs for concrete-frame buildings average roughly $2,200 per square metre, significantly lower than the current $4,500 per square metre cost for new high-rise construction in the North Terrace area. When developers look at the site of the former State Bank building or the brutalist edges of the Flinders University city campus, they see dated infrastructure. The architects who built them, however, see permanent bones that have survived five decades of South Australian heat waves and tectonic shifts.

As the July 2026 review period concludes, the Planning Minister is expected to release a updated Heritage Overlay map that will determine which of these sites receive permanent protection. For residents and business owners on Hindley Street or Gawler Place, the decision will dictate the visual character of the city for the next fifty years. Those interested in the history of the movement can visit the State Library of South Australia’s archival exhibit on 'Modernist Adelaide' throughout August to view original blueprints and hand-drawn renderings of these contested landmarks before the final heritage declarations are handed down in late September.
