Description

Construction years: 1928-
Physical description: Setting:
Development in the surrounding area is primarily low density residential, with single and two storey residences dominating the streetscape. Infill development in the neighbourhood comprises medium density interwar and 1960s apartment blocks and a primary school opposite the site on Griffiths Street (Heritage Division report).

The Balgowlah Zone substation is an elegant single and two storey structure. It is a refined and well detailed face brick building designed in the interwar stripped Classical style evidenced by the vertically emphasised form and faade detailing, parapet cornice and groupings of arched multi-paned windows. Stylistic elements also include recessed faade panels incorporating corbelled brickwork. Decorative elements include contrasting brickwork, repetitive arch motifs and cement rendered lintel plaques within the arches. Two large entrances with roller shutters provide access.

The substation is constructed with load-bearing face brick and incorporates brick arches to all facade openings. Large plant doorways are steel roller shuttered (Heritage Division, report, 9/11/2016).

The transformer bays and outbuildings sit atop sandstone foundations and a distinctive cut sandstone rock-face is prominent at the rear of the site. repetitive arch motifs and cement rendered lintel plaques within the arches. Two large entrances with roller shutters provide access.

History

Historical notes: Prior to 1928 the site was in agricultural use (Heritage Division report, 9/11/2016)

The Balgowlah Zone substation is a purpose designed and built structure dating from 1928. 'M.C. of S.ELECTRICITY DEPARTMENT SUBSTATION no. 191' and "1928" appear above the entrances in relief. It is a similar design to the 'PYMBLE' and RANDWICK' substations.

In 1926, the Municipal Council of Sydney acquired the subject land for the purpose of constructing a new substation to meet increasing demands for electricity in the Municipality of Manly. Prior to this the land was vacant. Balgowlah Zone Substation was erected on the site in 1928 with the following relief signage above the door 'M.C. of S. Electricity Department Substation no. 191, 1928'.

Upon its formation in 1951, ownership of the substation was transferred to MacKellar County Council (MCC). Elcom briefly took possession of the substation before MCC reacquired it in 1955. Substantial maintenance works were undertaken in 1976 including replacement of the boundary fence, repairs to the roof, and re-painting.

In 1979, MCC was absorbed into Sydney County Council (SCC), and thus SCC took over Balgowlah Zone Substation. The same year, SCC undertook transformer upgrade works including the installation of additional 11kV switchgear and the replacement of transformer cables. (Note: SCC would later become Sydney Electricity, which was absorbed into Energy Australia in 1996. In 2011 Energy Australia's electricity distribution network was rebranded as Ausgrid).

In 1980, following noise complaints, brick screen walls were constructed on the northern and eastern sides of the transformer bays. Although this served to reduce high frequency noise, noise complaints continued. To further reduce reverberation the transformer bays were enclosed by masonry construction and cooling fans installed. Further switchgear and transformer upgrade works were undertaken in 1985 (ibid, 2016).
