Infill development has long been a smart way to create new homes in established suburbs—but in 2025, Brisbane is entering a new chapter. With the housing crisis top of mind and infrastructure pressure growing across the region, planning policy is shifting to encourage more well-designed, medium-density housing—particularly within existing neighbourhoods.
If you’re a developer, investor or even a homeowner looking to unlock the potential of your block, now’s a good time to understand what’s changing, what’s possible, and where the opportunities lie.
Why infill is in the spotlight
Brisbane is growing fast. The 2032 Olympics may be driving some of the headlines, but the real story is population growth, affordability pressures, and the need for diverse housing close to transport, jobs, and services.
State and local governments are increasingly focused on infill development—that is, building new dwellings within existing suburbs, rather than pushing out to greenfield sites on the city fringe.
The result? We’re seeing momentum around:
More relaxed zoning in key areas
Faster approval pathways for low- to mid-density housing
Encouragement of dual occupancies, townhouses and small-lot homes
What’s changing in 2025
Here’s a quick overview of the key changes shaping Brisbane’s infill development landscape this year:
1. Medium density expansion zones
Brisbane City Council and the State Government are working together on targeted upzoning—particularly near major centres and transport corridors. Expect to see more areas reclassified for townhouses and low-rise units, including some that were previously limited to detached homes.
2. Support for dual occupancy and small-lot development
Small lot houses and dual occupancies are being increasingly supported in more neighbourhoods, especially where infrastructure already exists. This includes more flexibility around lot sizes, setbacks and access requirements.
If you’ve previously been told your site wouldn’t comply—it might be worth taking another look.
3. Faster pathways for compliant projects
There’s a strong push to reduce red tape for “code assessable” development, with Council streamlining assessment times for well-prepared applications that meet the planning scheme.
4. Focus on good design outcomes
Expect more emphasis on quality design, sustainability and neighbour-sensitive solutions—not just ticking planning boxes. Council wants to see infill that contributes positively to the street and local area. That’s where thoughtful architecture really matters.
Opportunities for developers and investors
For developers, this evolving policy environment means two things:
More sites are becoming viable
Well-designed, context-aware projects are more likely to get approved
If you’ve been sitting on a site, now’s a smart time to reassess its potential. Splitter blocks, corner sites, underutilised backyards, and lots near neighbourhood centres are all worth revisiting.
The same applies if you’re looking to retain one dwelling and sell or rent the other. Infill development isn’t just about yield—it’s about building value over time.
Tips before you start
If you’re thinking about pursuing an infill project in 2025, here’s what I’d recommend:
Get a fresh planning check. Even if you’ve reviewed your site before, the rules may have shifted. We work closely with trusted town planners like Murray Bell Planning Co, who keep a close eye on these changes.
Design to fit the context. Cookie-cutter solutions are less likely to fly. Council wants thoughtful, neighbour-friendly design that improves the streetscape and liveability of the area.
Balance yield with buildability. Think about how the homes will actually be constructed and lived in. Smart design = better return, smoother approvals, and happier end users.
Final thoughts
Brisbane’s housing landscape is evolving, and with it, the opportunities for thoughtful infill development are expanding. If you’ve got a site that you’re unsure about—or you’re considering an investment but not sure what’s possible—2025 could be the year to explore it seriously.
As an architect who works across both private residential and developer-led infill projects, I’m always happy to provide a clear, no-pressure view on what might work for your block and what to keep an eye on as the city continues to grow.
