Walk through South Perth today and it’s hard to separate the suburb’s identity from its apartment towers and the precincts that have evolved around them.

But while they might dominate the landscape, the real measure of a successful precinct has very little to do with the buildings themselves, and everything to do with what happens beyond their walls.

That idea is backed by research from Urbis Brisbane Director Kate Meyrick, an urbanist whose Doctor of Philosophy at Curtin University examined the relationship between major rail investment and long-term precinct performance, discussed on a recent episode of the Precisely Property Podcast.

Her doctoral work – On Track for Transformation: How Urban Rail and Activated Places Create Great Cities – analysed 26 cities and 38 rail corridors internationally, drawing on more than 100 measures across two decades.

Precincts with strong place quality, usually a well-designed public realm, walkability and a clear sense of character, did not simply perform well in isolation.

Instead, they acted, as Dr Meyrick described it, as a supercharger of other forms of capital – human, intellectual, environmental and financial.

She points to London’s King’s Cross and London Bridge as striking illustrations of this. Both precincts were built around stations of similar scale, with large tracts of land capable of the same uplift, yet one became one of the best-performing precincts in her global study, and the other the worst.

The difference wasn’t just the presence of rail and land. It was how deliberately each project was brought to market, and whether a clear vision – supported by a public realm established early to foster placemaking – could bind individual buildings into a cohesive place, rather than a fragmented collection of plots.

The best precincts borrow the character of the suburb surrounding them – its heritage, its scale, the way people already move through it – and treat it as the foundation to build from rather than an obstacle to work around.

The ones that get this wrong tend to dominate a location instead of enhancing it, adding density without ever becoming part of the place itself.

That restraint asks more of a developer than simply maximising what a site can hold, but it produces somewhere people actually want to spend time.

A precinct built only to perform for those inside it will always be narrower and less durable than one built to lift the neighbourhood around it.

The most successful precincts also change what a suburb is known for, a reputational shift that tends to outlast any single building within it.
