CML Building, Adelaide

From Engineering Heritage Australia


The CML building was constructed on the south-western corner of Hindley Street and King William Street over a nine-month period in 1934.

It is eleven stories above ground level, the highest permitted height at the time, and remained Adelaide’s tallest building for three decades until the construction of the AMP Building in the corner of North Terrace and King William Street in 1968.

The building was constructed using reinforced concrete.

After its successful use on the Brisbane CML building, the façade was constructed using Benedict Stone, a Queensland developed material that used crushed porphyry that was blended into a mix that could be poured into moulds. Similar buildings were constructed in Wellington, New Zealand and Port Elizabeth, South Africa.

In 1936 radio station 5DN – South Australia’s first commercial radio station – moved into the top floors. Two 30 metre masts were erected on the roof with antenna strung between. The towers were removed in 1956 when 5DN shifted to new premises.

The building was repurposed into a hotel in the 2000s and opened in 2015.
