The shape of the place

Houses with grounds, not yards

When the North Shore railway opened in 1890, Wahroonga became the place Sydney's successful built their country houses in town: Federation and Edwardian estates by architects like Howard Joseland and John Horbury Hunt, set in gardens rather than on blocks, along streets planted so well that a century later the trees are the suburb's signature. Hunt's timber Highlands went up in 1891; Hardy Wilson built Purulia for himself in 1913; and the pattern they set, a serious house in serious grounds, still defines the place.

Then, in 1950, the suburb of grand old houses acquired Australia's most famous new one. Rose Seidler House, built by a young Harry Seidler for his parents, introduced this country to modern architecture: glass walls, open plans, and a kitchen so electrically ambitious it was national news. The house of the future was built in Wahroonga, which we have always thought says something about the suburb.

Today nearly 18,000 people live here, three quarters of homes are separate houses, and the institutions are part of the fabric: the San on Fox Valley Road since 1903, Knox and Abbotsleigh with their daily tides, the village by the station. But for our trade the defining fact is the block itself. A Wahroonga property is not a house, it is a campus: gate, driveway, garage, garden, pool, studio, house, all wanting power, all a long way apart. That is the work, and this page is about how we do it properly.

The lie of the land

One address, six installations

Draw a typical block and the work draws itself. Everything wants power, and nothing is close to anything.

One address, six installations a Wahroonga block is a small campus, and distance is the design condition the street ↓ the main house board the gate intercom, camera, keypad the garage and now the car the driveway run the pool & cabana bonded, zoned, protected the studio its own sub-board the garden sealed, separate circuit runs here are measured in tens of metres the board, where every run starts a satellite circuit, sized for its distance not to scale, but honestly not far off

What it means: on a compact block, electrical design barely matters, because nothing is far from the board. On a Wahroonga block, distance is the whole game. Voltage drops over long runs, so cable is sized for metres as much as load. Satellites like studios and pool sheds earn their own sub-boards, so a fault out there stays out there. And the board itself has to carry the sum of everything the property has quietly accumulated, which is why our first question on a big block is always the same: when was the switchboard last sized against what it actually feeds?

Around the campus

The six satellites, and what each one needs

Every big block collects some or all of these. Each has its own rules, and its own way of going wrong when wired casually.

The gate

The longest run on the property, and the one that has to work in the rain. Motor supply, intercom, keypad and camera cabling trenched together in conduit at proper depth, on their own protection, coordinated with the gate installer.

The garage

Once a light and a door motor; now the site of the single biggest load the property has ever gained. Car charging starts with an honest look at the board and supply, then gets its own protected circuit, sized properly.

The garden

Path and feature lighting that survives real trees and real weather: sealed fittings, proper burial depth, cable sized for the distance, and the whole outdoor estate on separate protection so a wet fitting cannot darken the house.

The pool & cabana

The strictest rules on the property: zones around the water, bonding of everything conductive, safety switches on every circuit, and pump gear that gets full-length cable so it does not brown out at every start.

The studio

A small building deserving a small building's electrical spine: a sub-main sized for the run, its own sub-board, and then whatever the space is for, home office, teenage retreat, guest flat, wired once and properly.

The main house

Where it all comes home. The board sized against everything the block now feeds, wiring brought forward era by era, and lighting designed for rooms that deserve better than a grid of downlights.

How big blocks get done

The estate needs a plan, not a patch

Licence 387609C Licensed & insured

Big properties accumulate electrical decisions the way they accumulate garden sheds: one at a time, each sensible, the total never examined. The pool went in one decade, the studio the next, air conditioning after that, and every addition found room on a board sized for none of it. Our first visit to a Wahroonga property usually starts with untangling that history, and the most valuable thing we produce is not a repair but a plan.

The plan is simple to read: what the property carries now, what the board and supply can actually deliver, what is due for renewal and in what order, and what the next decade's wish list, the car, the second studio, the heated pool, will need in place before it can happen. Owners use it the way they use a garden master plan: not everything at once, but nothing done twice.

Then the work runs the way work on a family property should: scheduled around the household, gates and dogs and gardeners accounted for, each stage left tested, tidy and documented. Everything is certified: we lodge a Certificate of Compliance for Electrical Work within 7 days of testing, through the BCNSW eCert portal since 1 July 2026.

The houses themselves

Two Wahroongas, one standard of care

The Federation estates are the suburb's public face: Joseland and Hunt houses with ornate plaster ceilings, deep cornices, picture rails and joinery that has outlived every owner. Rewiring one is patient, respectful work. Routes go through the generous roof and subfloor spaces rather than the walls, cuts are planned and agreed before they happen, and lighting is designed for the rooms, roses restored to service, not a Swiss-cheese ceiling of downlights. Staged wing by wing, the family stays home throughout, and the house keeps every scrap of its character while gaining a modern electrical spine.

The other Wahroonga is the one Rose Seidler House announced: mid-century and modern houses whose clean ceilings and glass walls are just as unforgiving as ornate plaster, in the opposite way. There is nowhere to hide a lazy cable run in an open plan, so the planning happens before the tools come out, through roof lines, slab edges and joinery. And the vintage matters: wiring from the fifties is now seventy years old, whatever the architecture around it looks like, so the same honest board-first conversation applies in both Wahroongas.

In both, the switchboard is the tell. Ceramic fuses and no test buttons mean the house is running on borrowed protection, and the upgrade is a planned day. Our rewiring page explains what each era of cable means when the walls finally open.

Wahroonga electrical questions

How big a job is rewiring a full Federation house here?

Substantial, plannable, and almost never as disruptive as owners fear. A Wahroonga Federation house is large, but it also has generous roof and subfloor spaces, which are a rewirer's best friends. We stage the work room by room or wing by wing, keep the family living there throughout, protect original plaster, joinery and picture rails, and finish each stage tested and certified. The house gets modern wiring and a modern board without losing a scrap of the character that made it worth buying.

We are building a studio over the garage. What does it need electrically?

Treat it as a small building, because it is one. A proper sub-main sized for the distance from the house, its own small switchboard with safety switches, and then the circuits the space actually needs: power, lighting, data, air conditioning. Done that way, the studio runs independently, a fault out there cannot darken the house, and adding more later is an afternoon. Done as one long extension lead's worth of thinking, it becomes the circuit that always trips.

Can you wire a gate with an intercom, keypad and camera?

Yes, end to end. The gate is usually the longest run on the property, so the cable is sized for the distance, trenched at proper depth in conduit, and brought back to the board with the intercom and camera cabling run alongside. We coordinate with the gate installer's motor requirements, put the whole run on its own protection, and leave you with a gate that works in the rain, which is the actual test of a gate.

The pool is a long way from the house. Does that matter?

It matters more than the pool shop mentions. Pump, heater, chlorinator and lighting circuits all run the full distance from the board, so cable is sized for the run, not just the load, or the equipment browns out every time it starts. Around the water itself the rules are strict and non-negotiable: zones, bonding of conductive surfaces, and safety switch protection on everything. We wire pools end to end and certify the lot; our pool electrician page has the detail.

We keep adding things. Is the house's supply actually big enough?

The honest answer needs ten minutes of measurement, and it is the right question to ask before the next addition rather than after. A house that has gained ducted air conditioning, a pool, a studio and a car charger over the years can approach what its supply and board were sized to deliver. We assess the actual maximum demand, tell you plainly how much headroom is left, and where an upgrade is worthwhile, whether that is the board, the mains, or moving to a bigger supply, we quote it as a planned job with the network paperwork handled.

Can you light a Federation interior without butchering the ceilings?

Yes, and the ceilings deserve the care. Ornate plaster, roses and deep cornices rule out the scatter-gun downlight approach. We design lighting that respects the rooms: fittings hung from roses restored to service, picture lights and lamps on switched circuits, discreet modern light where it earns its place, and any cutting planned to the centimetre and agreed first. The result is a house that glows the way it was meant to, with none of the Swiss cheese.

Is a mid-century house different to work on than a Federation one?

Different rules, same respect. The suburb that holds Rose Seidler House has a quiet stock of mid-century homes whose clean ceilings and open plans leave nowhere to hide cable, so routes are planned through roof, slab edges and joinery just as carefully as in an ornate interior. Wiring of that vintage is also now seventy years old, so the same board and rewiring conversations apply, just navigated around glass walls instead of picture rails.

How does your pricing work?

Attending your job is a chargeable callout. We confirm what it costs when you book, and the price for the work itself is agreed before we start, so there are no surprises on the invoice.
