Why Densifying and Gentrifying Our Middle Ring Suburbs Is the Solution

Key takeaways

It’s no secret that Australia’s major cities are facing a housing crisis, but the “missing middle” – medium-density housing options like townhouses, duplexes, and low-rise apartments – are conspicuously absent in many of our capital cities.

The rigid planning and zoning regulations in many of our cities have effectively squeezed out the medium-density options, leaving little room for the townhouses and low-rise apartments that could cater to a diverse range of demographics.

Community resistance and NIMBYism are common obstacles to medium-density housing development. These fears and misconceptions often lead to delays in development or outright rejection of projects that could add much-needed diversity to our housing stock.

The missing middle is underrepresented in our housing market because developers are inclined to stick with what works best for their bottom line, which is high-density apartment blocks in inner areas or sprawling estates on the fringes.

Densifying and gentrifying our middle-ring suburbs is the solution to fix the missing middle problem, because it makes better use of the infrastructure that’s already in place and helps make public transport more viable.

Australia’s housing landscape is missing middle, but we can create vibrant, diverse communities that offer more affordable and sustainable housing options. By densifying and gentrifying our middle-ring suburbs, we are investing in the long-term liveability and prosperity of our cities.


It’s no secret that Australia’s major cities are facing a housing crisis.

With affordability at an all-time low and the dream of homeownership becoming more elusive for many, there’s one crucial piece missing from our housing puzzle – the “missing middle.”

This term refers to medium-density housing options like townhouses, duplexes, and low-rise apartments, which sit between high-rise developments and traditional detached homes.

These housing types have historically offered a more affordable option, yet they’re conspicuously absent in many of our capital cities.

So, why is there this gap in our housing market, and more importantly, how can we address it?

Why Is the “Missing Middle” Missing?

To understand why the missing middle exists, we need to examine the factors that have led to this situation.

  1. Planning Policies and Zoning Restrictions

One of the most significant obstacles to developing the missing middle is the rigid planning and zoning regulations in many of our cities.

For years, local councils have favoured either high-rise apartment buildings in the inner city or near CBD locations or traditional single-family homes in the outer suburbs.

This has effectively squeezed out the medium-density options, leaving little room for the townhouses and low-rise apartments that could cater to a diverse range of demographics.

Many of our middle-ring suburbs are zoned for low-density residential use, meaning that building anything other than a single-family home is either not permitted or subject to a lengthy and complex approval process.

In contrast, high-density areas have been zoned around train stations or on main roads to allow for the development of high-rise apartments, leading to an abundance of these types of dwellings in certain parts of our cities, but not much in between.

  1. Community Resistance and NIMBYism

We can’t talk about the missing middle without acknowledging the role that NIMBYism (“Not In My Backyard”) plays.

Residents in established suburbs often resist any form of change, especially when it comes to increasing housing density.

This resistance stems from concerns about increased traffic, loss of green space, or a perceived decline in property values.

While it’s understandable that people want to preserve the character of their neighbourhoods, this mindset has made it incredibly difficult to introduce medium-density housing, even when it makes perfect sense.

Unfortunately, these fears and misconceptions often lead to delays in development or outright rejection of projects that could add much-needed diversity to our housing stock.

  1. Economic Factors and Developer Preferences

It’s not just the councils and residents at fault – developers also play a role.

There’s a higher financial incentive for developers to focus on either high-density apartment blocks in inner areas or sprawling estates on the fringes.

This is because, up until recently, the economies of scale for larger developments make them more profitable.

In contrast, medium-density projects can be more challenging to finance and execute, with potentially lower profit margins, making them less appealing to developers.

Consequently, developers are inclined to stick with what works best for their bottom line, leaving the missing middle underrepresented in our housing market.

This has only been exacerbated by rising land prices, which further discourage medium-density development, as developers need to maximize the return on investment.

Why densifying and gentrifying our middle-ring suburbs is the solution

So what can we do to fix the missing middle problem?

The answer lies in looking at our middle-ring suburbs, the areas 10-25 kilometres from the city centre.

These suburbs are prime candidates for densification and gentrification, and here’s why:

  1. Efficient Use of Infrastructure

Many of our middle-ring suburbs already have established infrastructure – think public transport, schools, shops, parks, sports fields and other amenities.

By increasing housing density in these areas, we can make better use of the infrastructure that’s already in place.

It’s far more efficient and sustainable to build up and around existing infrastructure than to continue sprawling outwards, which requires costly new infrastructure investments.
