on north wing. Heritage listing Cronulla Post Office was listed on the Australian Commonwealth Heritage List on 22 August 2012 having satisfied the following criteria. Criterion A: Processes Cronulla Post Office, constructed in 1924 and designed by architect Edwin Hubert Henderson of the Commonwealth Department of Works and Railways, has historical significance deriving from its prominent location within central Cronulla, and its association with the growth in local development in the first half of the twentieth century. The building, originally comprising a post office, residence and telephone exchange, was relatively substantial and clearly intended to meet the needs of the developing area. Criterion D: Characteristic values Cronulla Post Office is an example of: a post office and telegraph office with quarters (second generation typology 1870–1929) an interwar era building in a Georgian Revival style the work of EH Henderson, Commonwealth Department of Works and Railways Typologically, Cronulla Post Office was constructed as a combined post and telegraph office with a residence at first floor level in 1924. The original layout of the postal functions at ground level have been removed and replaced with a standard post shop retail fitout and suspended ceiling form, however, the original layout, joinery and fixtures of the residence on the first floor are largely intact. The original porches flanking the postal hall have also been infilled and incorporated into the interior of the post office and an addition has been constructed to the north of the original building. These alterations have compromised the typological intactness of the building, albeit the upper level residence interior remains more intact. Architecturally and stylistically, Cronulla Post Office is a suburban post office in the Interwar Georgian revival style, a decade later than earlier post office designs in this style. Compositionally, the original building is marked by broad reversals of solid and void to its Cronulla Street façade in a symmetrical fashion, with the postal hall flanked by porches and a setback balcony to the first floor. The infilling of the flanking porch bays and the 1970s addition to the north of the building have compromised the symmetrical nature of the original building, although it remains a reasonably well crafted and finely detailed post office building. Criterion E: Aesthetic characteristics Cronulla Post Office is a good albeit altered example of the Interwar Georgian Revival style. The building demonstrates the strong massing, considered proportions, simple geometric forms and minimal detail typical
