Wahroonga's mix of eras
Mansions from the 1890s
Development took off after the North Shore line reached Milsons Point in 1893, and orchard land became large blocks with mansions and big Federation houses.
Infill through to 1980
Subdivision started near the station in the 1920s and spread outward through the 1940s and 1950s, continuing right through to 1980.
Heritage houses
Listed homes include Highlands (1891), Purulia (1913) and the Rose Seidler House (1948 to 1950).
Mostly owner-occupied houses
At the 2021 Census, 74.5% of Wahroonga's 5,785 occupied homes were separate houses, 38.4% were owned outright and 17.8% were rented.
Ausgrid network
Wahroonga is inside Ausgrid's network area. Report outages and lines down to Ausgrid on 13 13 88.
Rewiring a Federation house without wrecking it
The wiring in a house this old has usually been replaced at least once, but often in stages, so it's common to find a modern board feeding a mix of newer and much older cable. An electrician who specialises in older homes will test the circuits, map what's what and suggest a staged plan that avoids opening up decorative ceilings and joinery more than needed.
If the house is heritage-listed or in a conservation area, changes to the outside, like a new meter box position, can need council approval. Ask council before the work is booked.
Storms under the tree canopy
On 21 January 1991 a storm hit Wahroonga with winds of 145 km/h, and 37.5 mm of rain fell in six minutes at Fox Valley. The streets are still heavily treed, and Ku-ring-gai Council asks residents to call Ausgrid whenever trees and power lines are tangled together.
Trees on your own land near the service wire are your responsibility to keep clear, through an accredited contractor. Trees on council land or next door are Ausgrid's to clear.
Where we'd begin
In an older Wahroonga house we'd begin with a full test of the circuits by an electrician who works on heritage-era homes, then plan the rewire room by room. It's slower than ripping everything out, but it protects the house. Tell us your postcode and we'll match one licence-checked local sparky who does this kind of work.
