Power Street Heritage Precinct (HO26)

Power Street forms part of the western boundary of the Private Survey area in Williamstown. The citation reads its history through the 1890s depression. Speculative residential estates laid out near railway lines in the 1880s were left vacant for a generation, until the next wave of growth in the Edwardian and Interwar periods, which followed the development of local industries. Many early residents were employed at the railway workshops.

What survives on the east side is a very intact row of single-storey houses, mostly Victorian and Edwardian villas with some Interwar bungalows. They are predominantly weatherboard with hip and gable roofs, and they share a consistent setback, siting and scale. That row is the precinct the citation describes.

What applies here

Tree controls apply in HO26, limited to street trees. That is the one difference in the control table from the larger Private Survey precinct (HO27), whose schedule row applies no tree controls. External paint controls do not apply here; solar energy system controls do.

Why this precinct is protected

The citation's statement of significance defines the precinct as:

The Power Street Heritage Precinct, which comprises all land in HO26 and generally includes properties with a frontage or side boundary to Power Street, Williamstown (along the eastern side).

It finds HO26 of local historic and aesthetic significance. The historic case is the depression story above. The aesthetic case is that the east side is a cohesive group of representative housing, predominantly from the late Victorian and Edwardian eras, typical of the Private Survey subdivision in Williamstown and Newport.

A contributory property is one that adds to the precinct's significance. The citation says many of the dwellings have a high degree of external integrity, and rates the east side's integrity as moderate to high, with few non-contributory places. In the street itself, bluestone kerbing and gravel verges have given way to concrete and a sealed road.

One side of the street

The citation describes the precinct as the east side. On the west side, on the former railway reserve, recent housing has been built in imitation of period styles. The citation counts that as a loss. It removed the street's outlook to an open reserve and its visual connection to the railway and the railway workshops, and it depleted a row of Monterey cypress on the west side, probably planted in the Interwar years.

So the view across the road is not your reference. Design cues for a house in HO26 come from the east side's own run of villas: single storey, consistent setbacks, weatherboard, hip and gable roofs. The 2006 infill guidelines call a mock Victorian villa that replicates buildings in the street inappropriate in a heritage area, and the alterations guidelines say to avoid replicating heritage elements, because reproductions obscure the history and age of a place.

The streets in HO26

The schedule describes the precinct as: Power Street, Williamstown.

The schedule names Power Street without property numbers or a side. The citation is more specific: the precinct generally includes properties with a frontage or side boundary to Power Street along the eastern side, and every contributory property it lists has an even number. Power Street also appears in the street list for the larger Private Survey Heritage Precinct (HO27). If you are on the west side, or on a corner block with a side boundary to Power Street, check your address rather than going by the street name.

The citation places Power Street on the western boundary of the Private Survey precinct, but the planning scheme gives HO26 its own overlay. The HO27 guide covers the wider area.

The citation lists these properties as contributory:

• Power Street (even only) 2A, 8-28, 32-54, 58, 62, 64, 68, 74-88, 94, 98-104, 110-120 and 128-132

A property inside the boundary but not on the list is still in the overlay, and the 2006 guidelines apply to non-contributory places too.

The rules that decide your application

Private Survey Heritage Precinct Heritage Design Guidelines 2020 applies here. It is an incorporated document, listed in the schedule to Clause 72.04, so it forms part of the planning scheme and council's planners assess applications against it.

It is the same document that governs HO27 and six other precincts. As summarised in the HO27 guide, it treats single-storey scale as the baseline, with double-storey elements set back to minimise visibility from the street. It expects detached houses sited parallel to the frontage unless angled siting is a characteristic of the street, and it describes lot frontages of predominantly 10 to 15 metres, simple symmetrical single or double-fronted forms, horizontal weatherboard and pitched hip or gable roofs.

Council's 2006 guidelines for alterations and additions, and for infill development, in heritage areas apply as well. A rear addition that can't be seen from the street is preferred, side additions are strongly discouraged, and timber additions usually suit timber houses best.

Can I add a second storey?

There is no numeric height limit. The 2006 alterations guidelines use a sight line instead, drawn in section from eye level (1.7 metres above the ground) on the opposite side of the street, over your roof to the rear of the block. A second storey below that line has minimal visibility from the street. For an east-side house the viewpoint is the west side of Power Street, whatever has been built there. Street width and front setback move the line, so a figure from another street means little for yours.

The guidelines also want a second storey well back from the façade, behind the main ridgeline, set in from the side walls and no higher than adjacent buildings, which here are predominantly single-storey villas. Check the roof first: most roofs of 30 degrees pitch or more should be checked for room for an attic storey. The guidelines describe Edwardian roofs as usually 30 degrees, and Federation houses with complex roofs as particularly suitable.

Fences, garages and the details

• Tree controls apply to street trees only. The Monterey cypress row is on the west side, and neither the citation nor the schedule says whether those trees fall inside HO26's mapped boundary. If a tree near your property matters to your plans, ask council whether it is covered.
• The 2006 guidelines say no new front fence should be over 1300 mm, and that it should keep the street's heights, materials and ratio of solid to open.
• Garages and carports in the front setback are not favoured. Beside the house they should sit at least 2 metres behind the front façade. Double garages are not favoured, and new vehicle crossovers are discouraged.
• External paint controls do not apply, but the guidelines say never-painted surfaces should stay unpainted and paint should never be sandblasted off masonry.
• New work should be distinguishable from the old: no replicated period detail, and simple detailing on additions.

What gets approved here

This section will carry the local permit record — application volumes, approval rates, what refused applications were attempting, and any VCAT decisions. That analysis is in progress and will be published with its method and limits stated.

What to do next

Ask council for pre-application advice. A free call with a planner, before anything is drawn — the most useful hour in the process.

Then check your address to confirm which precinct you are actually in. A Clarity Consultation is a focused session on your specific house; Confidence to Buy applies the same thinking before you bid.
