Perth needs more housing within its established areas — on that, planners, government and the market broadly agree. But density alone does not create good neighbourhoods, and Perth’s first generation of infill proved it. The question now is what the next generation should look like.
Drive through Perth’s middle suburbs and you can read the history of infill policy in the streetscapes. The battle-axe subdivisions of the 1980s and 90s. The triplexes with three garage doors where a front garden used to be. The grouped dwellings that met every numerical requirement of the R-Codes and still made the street worse. None of these were designed by people who set out to build badly — they were the products of frameworks that measured density and forgot to measure quality.
Perth’s infill targets aren’t going away; the metropolitan planning framework has aimed for a substantial share of new housing inside existing suburbs for decades, because the alternative — endless fringe growth — carries infrastructure, transport and environmental costs everyone eventually pays. The real debate is not whether to do infill, but how to do it so established communities gain from it rather than merely tolerate it.
Contribute to the street, don’t just occupy it
The first test of good infill is the view from the footpath. A well-designed project presents doors, windows, landscaping and human-scaled elevations to the street — not a row of garage doors and a driveway. It respects the rhythm of the existing streetscape: setbacks that relate to the neighbours, rooflines that converse with what’s around them, materials that belong in the suburb even when the architecture is unmistakably contemporary.
This is not nostalgia. Streets where buildings address the public realm are measurably safer, more walkable and more valued by the market. The infill that established residents fight is almost never "new homes" — it is blank walls, dead frontages and streets turned into car storage.
Privacy is designed, not disclaimed
Higher density puts homes closer together; whether that proximity becomes conflict is a design decision. Successful infill manages overlooking through window placement, sill heights, screening and landscape — protecting both the new residents and the neighbours who were there first. Outdoor spaces should be positioned to feel private without being walled into gloom, and acoustic separation between dwellings deserves the same attention as visual privacy.
The transition between public and private space matters most of all. Entries, porches, courtyards and balconies should create activity and character at the boundary — the layered threshold that lets residents see the street without being on display. Get that transition right and density feels like community; get it wrong and it feels like exposure.
Homes, not units
Infill fails commercially when the product feels like a compromise — the "unit" a buyer settles for rather than the home they wanted. The next generation of infill has to clear a higher bar: genuinely usable outdoor space, not a token courtyard behind a bin store; natural light in living areas as a requirement, not a bonus; storage planned into the design — for bikes, tools, luggage, life — rather than added as an apology; and floor plans that work for real households, whether that’s a downsizer, a young family or someone working from home.
Landscaping belongs in this list too, integrated from the start rather than used to conceal poor planning. Mature trees kept where possible, deep-soil zones for canopy to come, gardens that will improve with age — these are what make higher density feel generous instead of extractive.
The unglamorous details decide everything
Parking and bin storage will never appear in a marketing render, but they have a major impact on whether a development feels considered or compromised. Cars must be accommodated without dominating the site or the street; bins need a home that isn’t the front setback on six days of the week; mail, meters and services all need places that were designed rather than left over. Projects that resolve these details early read as quality everywhere else. Projects that defer them advertise the deferral permanently.
Why quality infill is also the commercial answer
There is a persistent belief that doing infill well is a cost. The market evidence points the other way. Better-designed infill sells at a premium to the compromised product next door, sells faster, attracts owner-occupiers rather than only investors, and — increasingly important — earns the community acceptance that smooths approvals for the next project. As buyers get more discerning and planning frameworks put more weight on design quality, the gap between good and mediocre infill will widen, not close.
The next generation of Perth infill should offer the efficiency of higher density while retaining the comfort, identity and liveability buyers expect from a home. That’s the standard we hold our own projects to — and if you own a site in an established Perth suburb and want to know what considered infill could look like on it, we’d welcome the conversation.
