Architect in Coburg

Coburg has always been a suburb of additions. Californian bungalows extended in the fifties, brick veneers added out the back in the eighties, sleep-outs and sunrooms and lean-tos accumulating over a century of families making do.

Which means most of the houses we're asked to look at here have already been renovated at least once — often more than once, rarely well. The interesting question in Coburg usually isn't what do we add. It's what do we finally undo.

Most of our Coburg work is renovations and extensions to existing houses: opening the back of the house to the garden, adding a room for working from home or for family who stay, replanning a kitchen and bathroom that were last touched in the seventies. Occasionally it's a small building in the backyard instead.

Coburg homes we've designed

Both of these come from the same Coburg house: an interwar weatherboard, two parents working from home, two young children and family who visit from interstate. The written brief asked for four bedrooms and two living areas. We presented four genuinely different options rather than three sizes of one idea.

A Garden Room in Coburg: Why One Room Beat Four Options — what was actually designed. One north-facing room off the back of the house, under a skillion roof angled to the northern sun, doing four jobs at once: second living area, guest room, quiet place to work and the long-missing link to the garden. The option that ticked every box in the brief was the one we argued against, and the client's reason for choosing the garden room is the most useful part of the story.

The Option That Wasn't Meant to Be Built — the wildcard from the same project: a narrow library and work-from-home studio along the side of the house, with its own entry from the street and clad in recycled terracotta tiles to match the roof. It was never the likely choice. It was there to test the brief, and it changed what the family thought they were asking for.

Nearby in Merri-bek, A Staged Renovation in Brunswick West — a two-bedroom cottage, bought deliberately small, replanned for two people and designed to be built in stages.

What makes Coburg different

The planning ground is genuinely shifting. In March 2026 Coburg entered Stage 1 of the state government's Train and Tram Zone Activity Centres program. It sets a core around Coburg Station and a catchment roughly a ten-minute walk out — about 800 metres — with taller permitted heights close to the station stepping down toward the surrounding streets, plus sun-access protections for Bridges Reserve and City Oval.

If your house sits inside that catchment, the rules that apply to your block are not necessarily the rules that applied when you bought. That cuts both ways: it can constrain a design, and it can quietly change what your land is worth. Either way it's something to check before you commit to a scheme, not after.

Heritage is patchier here than people assume. Coburg has real Heritage Overlay precincts — the Newlands Estate is one — but they sit alongside long stretches of street with no protection at all. Two houses that look identical from the footpath can face completely different approval paths. Where the overlay does apply, all external changes need a permit, which catches people out on things they thought were maintenance.

Council also holds the Coburg Heritage Conservation and Streetscape Study from 1990–91 — five volumes of it. It's dated, but it's still the reasoning behind a lot of what gets protected, and reading the entry for your street is more useful than guessing.

Merri-bek City Council is the planning authority. Worth knowing if you're searching for anything: it was the City of Moreland until 2022, so a great deal of the advice still online refers to a council that no longer exists under that name.

The blocks are generous and the orientation is often wrong. Coburg's grid produces a lot of long, narrow allotments running east–west, which puts the good northern light along a side boundary rather than the back fence. Extending straight off the rear — the obvious move — frequently produces a large, dim room facing south. Getting light into a Coburg house is usually a problem of section and roof form, not floor area.

Renovating and extending the common Coburg house types

Interwar weatherboards and Californian bungalows. The bulk of Coburg's housing. Good street presence and generous front rooms, but the back of the house is usually a run of small rooms, a lean-to and a step down to the garden. The best move is often to leave the front rooms largely alone and rebuild the rear so living spaces face north and open to the yard — which is exactly what the Garden Room does.

Victorian and Edwardian cottages closer to Sydney Road and the station. Narrow, often semi-detached, with the familiar dark middle and a kitchen at the very back. Light from above — clerestories, a light well, a raised roof over the middle of the plan — usually does more than extra floor area.

Post-war brick veneers and 1960s–70s brick homes. Solid, usually on decent blocks, with low ceilings and windows that ignore the sun. These are some of the most rewarding houses to rework: the structure is sound, and changing a roof form or a few openings can transform how they feel.

Units and townhouses from the last forty years of infill. Tighter, with shared walls and body corporate rules, but small internal changes — a replanned kitchen, storage that works, a better connection to a courtyard — can go a long way.

Do you need a planning permit to extend in Coburg?

Often not under the zone. Since September 2025, extending a single house on a lot of 300 m² or more in the main residential zones doesn't need a planning permit under the zone — setbacks, overshadowing and overlooking are checked through the building permit instead. Under 300 m², a permit is needed, though a compliant design can often use the ten-day VicSmart process.

In Coburg, the things that most often change that answer are:

• A Heritage Overlay, if you're in one of the precincts.
• The activity centre controls around Coburg Station, described above.
• Flood controls. Parts of Merri-bek near Merri Creek and its tributaries, and along overland flow paths, are covered by a Special Building Overlay, and council has been working to extend that mapping. If it applies, it can set your new floor level.

Backyard studios and small second homes in Coburg

Coburg's long blocks suit a small building at the back. Since late 2023, a self-contained small second dwelling of up to 60 m² can be built on most residential lots without a planning permit where no overlay applies (it still needs a building permit). For a studio or home office that isn't a full dwelling, the rules are simpler again. The Option That Wasn't Meant to Be Built shows what a narrow, purpose-built work-from-home room can look like — and why it's worth testing one even if you don't build it.

The trap we see most often

Renovating around the last renovation. There's often an existing addition that is structurally sound, superficially fine, and quietly the reason nothing else in the plan works — badly oriented, at the wrong level, blocking the only sensible path for light.

Keeping it feels like the thrifty choice. It generally isn't. We'd rather show you honestly what it costs to remove it and what you get back, and let you decide with the number in front of you.

The other trap is designing to the room count. A brief that says "four bedrooms" can be met and still leave the house feeling no better to live in. In the Garden Room project, the option that satisfied the brief on paper would have swallowed the garden; the one that got built added less floor area and changed far more about daily life.

How we'd start

A conversation, unhurried and free, about the house and what's been holding you up. You can also write your brief first — ten questions, and you'll have a written brief to bring to that conversation. Then an honest read on whether the idea is sound — including whether your block sits inside the new activity centre catchment, and what that means for you.

If it's promising, a Clarity Consultation gives you a focused architect-led session on your options. The Big Picture is the full masterplan. Neither starts with a sales pitch.

If you haven't bought yet, Confidence to Buy is the pre-purchase version of the same thinking — and in a suburb where the zoning is actively being redrawn, it earns its keep.

Do I need an extension, or just a better layout? is the question worth answering before anything else in a house that has already been added to.
