Statement of significance:

Substation, Paddington, may not reach the threshold for State heritage significance under any of the significance assessment criteria. It is recognised for its local historic, aesthetic, research and rarity values.

Substation, Paddington, demonstrates aspects of the rapid 1920s suburban expansion of Sydney's electricity network during the period when Bunnerong Power Station was under construction, however it is not distinctive among the many distribution substations built in this period.

While it is one of the older substations still in operation in Ausgrid's network, this does not alone confer State significance, given the number of comparable 1920s distribution substations across Sydney and regional NSW during the same period still extant.

Substation, Paddington, is noteworthy for its response to a corner site and sloping topography, and as a well-executed interwar Free Classical design incorporating a rare, curved Functionalist wall. These qualities make a strong contribution to its immediate streetscape. However, its architectural expression is consistent with contemporary substation design and does not demonstrate a level of architectural innovation, distinctiveness, or influence that would elevate it to State significance.

Description

Designer/Maker: City Building Surveyor's Dept. (Robert Hargreave Brodrick, James Henry Merriman)
Builder/Maker: Municipal Council of Sydney, City Building Constructor's branch
Construction years: 1926-1926
Physical description: SITE
The wider site, spreading east from the corner of Young Street and Weedon Avenue, incorporates several buildings and a connecting transformer yard that demonstrate expansion of the electricity network.

The earliest on site is the purpose designed and built structure, originally known as Substation (Paddington) or Substation No.9, dating from 1926 (this only is the State Heritage Register item).
NB: The remainder of the site including Paddington Zone Substation is not listed on the State Heritage Register.

The wider site comprises several built elements, embracing two main phases of substation construction:
- Substation No.9 (built 1926), to the corner of Young Street and Weedon Avenue (the SHR item); '
and adjoining it to the east (NB: This is the item listed on the NSW State Heritage Register (only).
-------------------------------------------------------------------------------------------------------------------------------------------------

Substation Paddington, aka Substation No.9 (SHR item), occupying Lot 2 DP 181526:

EXTERIOR
Substation, Paddington is a fine brick* building, designed in interwar Free Classical style. It is an unusual design with an Interwar Functionalist style curved wall responding to the corner site, that follows the corner and maximises internal space. A dominant classical rendered cornice below the parapet is the building's main decoration.

The pediment above the central (main) entrance doorway in the centre of the Young Street facade originally carried the words 'ELECTRICITY SUB-STATION' with 'No.9' above the roller shutter door. Only the No.9 remains.

The main entrance is flanked by multipaned timber windows protected with wire mesh and ventilation louvers.

On Weedon Avenue a small door led to the Public Light Control Board and a secondary entrance with roller door is marked by a rendered parapet bearing 'No.9' that frames the door and two windows covered in steel mesh.

External materials: Face brick, cement render, steel roller shutter
(NTA (NSW); Schwager Brooks 1994 volume 3: 199).

*it is not tuck-pointed (as it was previously described) - no coloured bedding mortar or contrasting bead is visible (as befits tuck pointing (Woollahra Municipal Council update, 18/3/2026).


INTERIOR
The interior comprises two major spaces on the building's northern and central part, and a small electric lighting room towards its south-eastern corner (Young and Weedon Street) corner, but facing the latter street, near that corner.

These spaces are a transformer room and a battery (formerly switch) room. The transformer room has stairs down to the battery room, internally.

There are roller door entries facing both Young Street and Weedon Avenue. The main entry was from Young Street. A pedestrian door gives access from the Electric Lighting room onto Weedon Avenue.

Internal walls are painted face brick. Steel girders support a concrete roof.

A linear roof lantern (skylight) allows light into the transformer room from above, in addition to windows to the sides. A rank of batteries is in the battery room. A pit in the floor behind the row of transformers houses cabling.

After construction of the adjacent Zone substation and it coming into service in 1940, the 1927 substation became an annex of the Zone substation, and was used to house the 5.5kV/415V auxiliary transformers, batteries and street lighting control apparatus. The 5.5kV switchgear was removed and the (Substation) No. 9 designation was discontinued, being re-assigned to a new substation at Mascot in 1941. In 1951, the former Substation No. 9 was reclassified as a separate substation, after re-installation of 5.5kV switchgear. The recommissioned substation was designated No. 935 County Avenue and remains in service as such (Pennington 2012: 19).

From a technical electrical perspective, the equipment with the site has been largely changed from its original configuration.
Physical condition and/or
Archaeological potential:
Generally good. Some gutters and downpipes damaged. Minor cracking to masonry, Rear garden very overgrown (North 2007).

Good (1994: Schwager Brooks 1994: 199)
Date condition updated:26 Feb 26
Modifications and dates: 1926: the original, coloured plan for the new substation, dated 8/4/1926, shows a Free Classical style building with main entrance on Young Street, and secondary entrance on Weedon Avenue. Interestingly, the elevation facing the corner of Young and Weedon was originally designed as a flat masonry wall. At some point during design or construction phase, this corner of the building was changed to be a curved wall, presumably to make the most of an unusual triangular shaped site. (Murray 2025).

c.1929 (NB: Zone Substation: outside and alongside SHR curtilage): MSC acquired land behind (east of) the (1926) substation by purchase and resumption. The onset of the Great Depression curtailed the capital works of the Electricity Department.

1936: (NB: Zone Substation No. 342, outside and alongside the SHR curtilage): planning to construct the new (30kV zone) substation (to take 30kV feeder cables from Bunnerong Power Station) and convert this to low voltage for local use. 1937 development application lodged, but Paddington Council objections led to suspension of the tender process and rethinking. After re-specification, the tender was awarded in 4/1938. It was completed by the end of 1939, designated (Zone) Substation No. 342, with entrance on Weedon Avenue, while the Young Street elevation (adjoining Substation No. 9, to its east) was built to the property boundary, flush to the street (Murray 2025).

After 1940's construction of the adjacent zone substation and it coming into service, the 1927 substation became its annex and was used to house the 5.5kv/415V auxiliary transformers, batteries and street lighting control apparatus. The 5.5kV switchgear was removed and the (Substation) No. 9 designation was discontinued, being re-assigned to a new substation in Mascot in 1941. (Pennington 2012: 19).

1951: former Substation No. 9 was reclassified as a separate substation, after re-installation of 5.5kV switchgear. The recommissioned substation was designated No. 935 County Avenue and remains in service as such (Pennington 2012: 19).

1950s+: alterations to meet capacity demands. New underground feeder cables were laid, and extra transformers installed. (Murray 2025).

1960s: core inspection bay converted into a control room. (North 2007).

1967 Young Street excavated to lay new underground cables into the switch house. The substation has undergone several internal changes since being put into service, although the outward appearance of the buildings has changed little (North 2007).

The building has been extended a number of times. Roof replaced. Gutters and downpipes replaced in a mix of copper and zincalum(e). Doors replaced. Some vents replaced. Later timber and chain wire fences. Arch bars replaced (North 2007).

Late 1990s: control facilities relocated to the former 33kV reactor room, and new fire protection equipment was installed in the former core inspection bay.

2000: the exterior of the former 33kV switch house building was damaged by a transformer explosion and subsequent fire in November 2000, but was later restored to its original appearance, except for the bricking in of the (switch house's) window openings (Pennington 2012).
Current use: electricity substation
Former use: Aboriginal land, town lot

History

Historical notes: Paddington is on land of the Gadigal of the Eora nation (AIATSIS 2016), which stretches from the southern shore of Sydney Harbour to today's Petersham, and which practically and spiritually sustained the Gadigal for millennia. Early European accounts noted the area today called Paddington as the place of the Maroo, a path along the ridgeline long used by local Aboriginal people as trading routes between farmed grasslands or bountiful fishing areas (Heiss & Gibson 2015).

The rich archaeological and historical record of harbour allows us to recreate something of how Aboriginal people used Kogerah - as they called Rushcutters Bay - and its Paddington hinterland in the centuries before Europeans arrived. As a resilient and innovative community, they continued to adapt their lives, co-existing around the bay until the turn of the twentieth century (Elmoos 2019). Following initial European colonisation, much of the Aboriginal population of Sydney died due to the smallpox outbreak of 1789. Following this, Aboriginal people regrouped, living in camps east of Potts Point at Barcom Glen and downstream on public land at Rushcutters Bay, throughout the 19th century (Irish n.d.). Despite the impact of colonisation, Gadigal culture has survived and Aboriginal people have continued to retain links to the area.

PADDINGTON:
This suburb took its name from the London borough. It was Sydney's first early suburb that was not self-sufficient - its inhabitants had to go away each day to their places of employment.

The area developed after a road was constructed to link up with a pilot station to be built at Watson's Bay. John Palmer, commissary, refused to allow people to cross his grant, so the road had to follow a roundabout way through Paddington to bypass (it).

It was not until 1838, when it was decided to build a new barracks in Paddington, that life came to the area. Once soldiers and families moved here, shopkeepers followed. Builders moved in and put up 3,800 houses from 1860 -90. (Pollen 1988: 195-7).

EARLY ELECTRICITY NETWORKS IN NSW
Prior to introducing electricity in NSW, streets were lit with gas and houses used gas, kerosene and fat oil lamps, and candles. Technological advances in the 1870s and 1880s made electricity a feasible lighting and power alternative. Early supply was from small generators and early providers of networks were principally municipal councils.

The first instance of NSW's municipal electric power supply was streetlighting in regional centres experiencing major growth in the 1880s. Tamworth and Young were amongst the first examples, with Tamworth receiving electric streetlights in 1888 and Young in 1889. (Penrith City Council 2021).

ELECTRIFICATION OF SYDNEY
Sydney's first public demonstration of electric light was in 1863 when Sydney Observatory was illuminated in honour of the Prince of Wales's marriage (Australian Energy Regulator 2007, p. 2). Early supply was from small generators scattered throughout the city for specific buildings or events.

Large-scale production was in its infancy in NSW in the 1890s, and the number of facilities constructed to generate or distribute electricity was relatively insignificant compared to municipal gas works established in that decade. Local municipalities pushed for legislation allowing them to generate electricity, build infrastructure, light streets and supply public and private places. Sydney's first council to generate and supply electricity to private homes, businesses and street lights was Penrith, which established an electric light station in 1890 (Nepean Times 1957, p. 1). Another light station was built closer to the city at Redfern in 1891.

The wealthiest municipality, the Municipal Council of Sydney (MCS), got State government consent to establish its own networks and supply private customers under the Municipal Council of Sydney Electric Lighting Act 1896. Its Electric Lighting Committee was established in 1898 to bring the network to the MCS area, reaching from Millers Point to Chippendale, Surry Hills and Moore Park (City of Sydney n.d.). While originally supplying the MCS area only, it soon became the biggest supplier of electricity in NSW.

Sydney's first major central power station was the Ultimo Powerhouse (listed on the State Heritage Register (SHR) as part of Powerhouse Museum Complex, Ultimo (SHR 02045)), built in 1899 by the NSW Department of Public Works to power the electric tram network. Construction of White Bay Power Station, Rozelle (SHR 01015)) followed in 1913 (Dunn, 2008). Trams were central to Sydney's growing population and economy and electrifying steam tram lines occupied much of 1900 to 1910.

MCS's first power station supplying street lighting and private use was at Pyrmont, opened in 1904. While earlier 'electric light stations' were small power stations supplying a small area, large power stations required the technological development of several types of substations to convert electricity to lower voltages for private use. Substations were designed to house transformers and other bulky equipment, such as AC to DC convertors, switchgear and batteries. Two types emerged, the zone and distribution substation. Zone substations were large complex facilities receiving power from bulk supply power stations such as Pyrmont and reducing voltage for local distribution. Distribution substations reduced the voltage further and supplied customers.

City Building Surveyor and City Architect Robert Hargreave Brodrick designed Pyrmont Power Station, and his branch designed hundreds of substations across Sydney to be substantial, ornamental pieces of civic infrastructure (Vade Mecum 1906, p. 200). The quality of design and construction was high, moving beyond functionality to fine civic architecture that sat comfortably in its surrounds. Land for them was either purchased in negotiation with owners or acquired by MCS through resumption if necessary. All stand-alone substations until 1936 were designed by MCS's City Architect & Building Surveyor but built by various parties.

In 1904 MCS built its first six distribution substations: Town Hall (Sydney), Lang Park (Sydney), Athlone Place (Ultimo), Pyrmont Street (Pyrmont), Oxford Street (Darlinghurst) and Nicholson Street (Woolloomooloo).

MCS first began supplying other areas of Sydney in 1905. A small substation was built to supply the Royal Hospital for Women in Paddington and another for Camperdown Children's Hospital (Murray, 2025).

Smaller private companies supplying city businesses were bought by MCS from 1907-13. MCS quickly established itself as one of two primary suppliers in Sydney, with the Electric Light and Power Supply Corporation (ELPSC) supplying electricity from Balmain Power Station to inner western suburbs from 1909 to 1956. In 1910, four municipalities entered agreements with MCS to extend mains into their areas, a rapid escalation to the extent of the network.

By 1914 MCS supply reached 23 municipalities outside the city centre, in the largest electricity network in NSW. The subsequent rapid expansion of the network in the 1920s was on a scale unprecedented in Sydney or the State and this continual network expansion required constructing additional infrastructure throughout greater Sydney. This means that a significant portion of MCS's substations were built from 1921 onwards.

PADDINGTON
Paddington (named after the London borough) was Sydney's first early suburb that was not self-sufficient. Its inhabitants had to leave the suburb daily to commute to and from their places of employment.

The area developed after a road was constructed to link up with a pilot station to be built at Watson's Bay. John Palmer, commissary, refused to allow people to cross his grant, dictating that the road had to follow a roundabout way through Paddington.

It was not until 1838, when it was decided to build a new barracks in Paddington, that the area began to grow substantially. Once soldiers and families moved here, shopkeepers followed. Construction rose with 3,800 new houses constructed from 1860 -90. (Pollen 1988: 195-7).

PADDINGTON ELECTRIFICATION
The original 1905 Substation No.9 Paddington was built in Young Street to power a new wing of the Royal Hospital for Women. Two years later, power supply from the original substation was extended to Paddington Town Hall. Paddington Municipal Council was slow to implement innovations like electric street lighting and electrification of the area was extended in an uncoordinated way.

SUBSTATION, PADDINGTON
Notification for land resumption for the new substation in Young Street was gazetted in February 1926. The land was across the road from and replaced the original substation. Construction by MCS commenced by August 1926. Bunnerong Power Station was under construction at this time, and it is likely MCS was anticipating future network needs by acquiring land and building a new substation.

The original, coloured plan for the substation, dated 8 April 1926 shows a Free Classical style building with main entrance on Young Street and a secondary entrance on Weedon Street. Interestingly, the elevation facing the corner of Young and Weedon Streets was originally designed as a flat masonry wall. At some point during design or construction, this was changed to be curved, presumably to make the most of unusual triangular site.

It is unclear who designed the 1926 substation. The original plan is unsigned, but annotated 'Approved by A.G.M.' Like all substations built by MCS, it was executed within the architectural branch of the City Building Surveyor's Department.

MODIFICATION INTO PART OF A ZONE SUBSTATION
Plans for a Zone substation to accommodate increased demand and wider distribution from Bunnerong Power Station were underway by 1929. MCS acquired the land behind Substation, Paddington, by purchase and resumption. The Great Depression curtailed capital works and in 1935 the whole electricity undertaking was transferred from MCS to Sydney County Council (SCC). Planning for the new substation commenced in 1936.

The zone substation was working by late 1939. The entrance to 'Substation No. 342' was on Weedon Avenue, and Substation, Paddington, was incorporated into it.

In 1952, the NSW Electricity Commission (Elcom) became overall State authority providing electricity in NSW, and SCC generating assets were transferred to it. Elcom controlled NSW's electricity until dissolved with the Sydney Electricity Act 1990. A series of private and public entities now provide electricity and its infrastructure in Sydney, overseen by the NSW Government. Ausgrid now manages most active distribution and zone substations (excluding the high-voltage transmission network).

Substation, Paddington, has continued in service as part of the zone substation since 1939 and, equipment upgrades notwithstanding, remains largely intact.

Assessment of significance

SHR Criteria a)
[Historical significance]
Substation, Paddington, was constructed as a distribution substation with multiple purposes: to supply power to homes and businesses, to supply power to street lighting and to directly power the Royal Hospital for Women, Paddington. It replaced a very early substation which powered one wing of the hospital.

Substation, Paddington, demonstrates aspects of the rapid 1920s suburban expansion of Sydney’s electricity network during the period when Bunnerong Power Station was under construction, however it is not historically distinctive among the many distribution substations built in this period.

While it is one of the older substation buildings still in operation in Ausgrid’s network, its status as the third-oldest operational substation does not alone confer State significance, given the number of comparable 1920s distribution substations across Sydney and regional NSW built during the same period that remain extant.

As a distribution substation from the 1920s, built to replace an existing substation, it is unlikely to reach the State threshold for historic significance. It is recognised for its historic value at a local level.
SHR Criteria b)
[Associative significance]
Substation, Paddington, is generally associated with Robert Hagreaves Brodrick who made a significant contribution to the electrification of NSW. As City Architect, Brodrick would have overseen the design and construction of Substation, Paddington. However, it is unclear who actually designed this particular substation, unlike other examples on the State Heritage Register.

Substation, Paddington’s association with Brodrick is therefore no higher or more distinct than the other substations from this period that were built to designs overseen by Brodrick, noting that there are more than 300 such substations. As such, it is unlikely to reach this criterion at a State or local level.
SHR Criteria c)
[Aesthetic significance]
Substation, Paddington, is a fine example of an externally intact predominantly Interwar Free Classical style building. The substation has a distinct curved exterior wall addressing the site's street corner. This element is atypical of this style and is the only known example of its kind in Sydney.

Constructed predominantly of brick with sandstone detailing, Substation, Paddington, is a visually pleasing element in the historic suburban precinct of Paddington. It demonstrates, as do the majority of Municipal of Sydney Council built substations, the deliberate choice of architectural style to complement the surrounding urban environment. The Municipal Council of Sydney was known for its commitment to producing quality civic infrastructure as part of its electricity undertaking.

Substation, Paddington, was designed and built as an electricity distribution substation supplying the Royal Hospital for Women, public street lighting, residences and businesses. It did not incorporate any particular advances in technology or open up large new areas of Sydney (NSW’s major metropolis) to electrification.

The aesthetic values of Substation, Paddington, while noticeable, do not reach the State threshold and its technical values are purely local. It is recognised for its aesthetic values at a local level.
SHR Criteria d)
[Social significance]
Substation, Paddington, is unlikely to reach this criterion at a State or local level.
SHR Criteria e)
[Research potential]
Substation, Paddington, is unlikely to reach this criterion at a State level. It is recognised for its research potential at a local level.
SHR Criteria f)
[Rarity]
Substation, Paddington, is a distinctly designed distribution substation which demonstrates a specific architectural response to a difficult corner site and sloping topography. However, many others were also individually designed to respond to their local context.
SHR Criteria g)
[Representativeness]
Substation, Paddington, is an example of the work of the Municipal Council of Sydney and was overseen by Robert Hargeave Brodrick, City Architect, who oversaw the design of approximately 300 substations. It demonstrates the high degree of craftsmanship put into Municipal Council of Sydney’s electrical infrastructure.

As a distribution substation, built to service an area already electrified for decades, it is unlikely to represent a State significant period or achievement in the Municipal Council of Sydney’s undertaking or in the expansion of the NSW electricity network.
Integrity/Intactness: Little external alteration since it was built in 1926. Various internal equipment upgrades over time.
