Granular building-height detail for all 15 million addresses, rolled up to the Microburb, the small local pocket far finer than a suburb, and worked out even where no public record exists. To our knowledge, no one else has it this complete or this local. Here is what it reveals.
By Luke Metcalfe · Founder, Microburbs ResearchPublic records tell you how tall a handful of buildings are, then fall silent for most of the country. We filled the gaps. We pulled together every scrap of height information available and, where there was none, used clever data work to infer it, for every one of Australia's 15 million-plus addresses. Then we rolled it up to the Microburb, the small local pocket far finer than a suburb. The result is the most complete and most local map of how tall Australia is built that we know of. Everything below sits on it, from councils and planners checking density, to the surprising answer it gives on capital growth.
We measured how tall the buildings are at more than 15 million addresses, then matched 250,000 real resales to those heights and compared each sale to how its own local area moved over the same years, from 2018 to 2026. Height made no reliable difference. Compared like for like, a home in a 40-storey tower and a home on a single-storey street grew at the same pace as the streets around them.
Look at the raw figures and houses do appear to beat apartments. But that gap is about where apartments sit, in already expensive inner-city areas, not about height. Tall buildings cluster where land is scarce and new supply is hard to add, so height is really telling you about supply, not about which way prices head next. No measured effect on capital growth.
What a growth edge is worth, and why height is not it. A 1% per year edge over your neighbours, compounded across a decade on an $800,000 home, is worth roughly $90,000. That edge is real and worth hunting. Our finding is simply that building height is not where you will find it, so do not pay a premium for low-rise, and do not write off a tower suburb, on height alone.

To make it concrete, here are the two ends of the scale. They could not look more different, yet neither suburb's height told us anything about how its prices moved against the homes around it from 2018 to 2026.
The most vertical suburb in the country. The typical home sits around the 36th floor, and towers climb to 92 storeys. A wall of high-rise on the Yarra's south bank.
Sydney's centre averages about 14 storeys, with its tallest residential tower reaching 67. One of the densest vertical areas in the country, but a clear step below Melbourne's high-rise core.
A newer estate of almost entirely single-storey homes. The opposite of Southbank in built form. Wide streets, freestanding houses, barely a unit block in sight.
The growth verdict on these extremes. These two suburbs are here to show the range of how Australia is built, not to prove the point on their own. The growth test ran across all 250,000 resales in the country, not three hand-picked suburbs. Taller and shorter alike, once each home was compared to its own local area from 2018 to 2026, height did not separate the winners from the losers.

Stop using building height as a buy or avoid signal. It does not predict growth, in either direction. The catch is the difference between how tall a suburb already is and how much new height is about to be added next door. The first does not move your returns. The second can. What height genuinely tells you is that second thing, and it is just as useful: supply and competition. A suburb adding towers is adding stock that will compete with yours for tenants and buyers. A suburb of protected single-storey streets is one where new supply is hard to add.
So read height as the supply side of the equation, then judge the suburb on how its prices have actually behaved and what new building is being approved nearby, the things that really move a market. That is exactly what a suburb's Microburbs report lays out in one place: how tall it is built, what is in the approval pipeline, and how its prices have tracked over time.
The real risk is not the towers next door. It is a flood of homes just like yours. Buildings already standing nearby, even tall ones, tend to bring shops, transport and demand. What actually drags growth is a wave of brand-new homes much like yours arriving at once, the competition you have to sell against. We found the same thing in two companion studies: the suburbs with the most new building going up nearby grew the slowest, and the quiet, hard-to-copy low-density suburbs grew the fastest.
Three questions this lets you ask: Is my suburb about to be flooded with new high-rise stock that competes with my unit? Is this low-rise street protected from new supply, or about to be rezoned? And the big one: if height does not drive growth here, what does?
This is built on every address in Australia, more than 15 million of them across all states and territories, with each building's height pulled from every available source and, where none exists, inferred with clever data work, current to 2026. To test the link with capital growth, we matched 250,000 real resales through April 2026 and compared each one to how the homes right around it moved over the same years, so a fast-rising city is never mistaken for a fast-rising building. The height map covers every suburb in the country; the growth test used every suburb with enough resales to compare.
Microburbs measures Australia at the level of small local microburbs, so a single suburb is never treated as one uniform blob. Your street can look very different from the suburb's headline.
