“Should we sell up and buy bigger, or just add on to what we’ve got?”
More and more Brisbane families are picking the second option. Moving costs a fortune in stamp duty, agent fees, and stress. A well-planned home extension keeps you in your neighbourhood, adds real space, and often costs less than upgrading to a bigger mortgage. Here’s why staying put is the new moving.
Let’s be real-Moving is a nightmare
You know the drill. You’ve got two kids, one on the way, and the house feels like a shoe box. Your first thought is: “Let’s sell and find something bigger.”
Then you look at real estate apps. Prices are through the roof. Anything with an extra bedroom is $200k more than your place. Plus stamp duty, plus agent fees, plus moving trucks, plus a month of takeaways while you unpack.
Suddenly, adding a room at the back doesn’t sound so crazy.
That’s exactly what Brisbane families are figuring out in 2026. Instead of listing their home, they’re calling up home extension services in Brisbane and asking: “Can we just push out the back wall and build a new living area?”
Spoiler: yes, you can. And it’s often cheaper than moving.
What’s pushing people to extend instead of move?
A few things have changed in the last couple of years.
1. Stamp duty is ridiculous
On a million-dollar home, you’re paying around $38,000 in stamp duty. That’s money you never see again. An extension might cost $80k–$150k, but at least that goes into your own home’s value.
2. Interest rates are still high
If you sell and borrow more for a bigger place, your monthly repayments jump. Extending usually means a smaller loan – or using savings you already have.
3. Good Brisbane streets are hard to leave
You know your neighbours. You know the best route to school. You’ve planted that mango tree out back. Giving that up for an unknown street? No thanks.
4. Building costs have settled
During covid, extensions were crazy expensive and slow. Now, most home extension services in Brisbane have reasonable wait times and prices you can actually compare.
The top extension types Brisbane families are asking for
Not every extension is the same. Here’s what’s popular right now.
The rear living pod
You knock out the back wall and add a big open room. New kitchen, dining, living all in one. The old kitchen becomes a butler’s pantry. This works for Queenslanders and post-war homes.
The second-storey addition
Got a single-storey house on a small block? Go up. Add three bedrooms and a bathroom upstairs. Downstairs becomes office and guest space. Costs more than a rear pod, but you keep your whole backyard.
The granny flat conversion
Some families are turning old garages or sheds into a teenage retreat or a home office with a bathroom. No full kitchen needed just a wet bar. Cheaper and faster than a big extension.
The “bump out”
Push one wall out by two metres. That’s it. Suddenly your tiny living room fits a proper couch and a dining table. This costs as little as $30k–$50k and doesn’t need major engineering.
What about council rules?
Yeah, you can’t just start swinging a hammer. Most extensions need approval from Brisbane City Council. But here’s the good news: a lot of rear extensions fall under “accepted development” if you stay within certain size limits.
A decent home extension services in Brisbane team will handle all that for you. They check height limits, boundary setbacks, and flood overlays. They also talk to neighbours if needed.
Pro tip: avoid the cowboy builders who say “she’ll be right” without a permit. That’s how you end up tearing down your new room six months later.
Real talk: How much does it cost?
Let’s give you ballpark numbers for 2026. These are from actual Brisbane quotes.
| Type of extension | Rough cost |
| Single-room bump out (2m x 4m) | $30k – $50k |
| Rear living pod (6m x 6m, basic finish) | $80k – $120k |
| Second-storey addition (3 beds, 1 bath) | $200k – $300k |
| Granny flat conversion (no full kitchen) | $40k – $70k |
Compare that to selling. Agent fees alone are 2-3% that’s $20k-$30k on a million-dollar house. Then stamp duty on the new place. Then removalists. You’re easily at $60k+ before you’ve even unpacked a single box.
The Emotional Side – why families stay
Money isn’t everything. A lot of people extend because they genuinely love where they live.
One family in Camp Hill told me: “We looked at moving to a bigger place in Carindale. But our kids would have to change schools. Our morning walk to the café would be gone. And we’d lose our lemon tree that my dad planted.”
They spent $110k on a rear extension instead. Now they have a huge family room that opens to the backyard. Same school, same neighbours, same lemon tree.
Another family in Built Bayside went up instead of out. They added two bedrooms and a study upstairs. The mum works from home in the study. The kids have their own rooms. And they still walk to the train station every morning.
You can’t put a price on that kind of continuity.
What to watch out for
Extensions aren’t all sunshine. Here’s the messy stuff nobody talks about.
- Living through dust and noise for 8-16 weeks, you’ll have tradies arriving at 7am. Plan to use the backyard or go to cafes a lot.
- Unexpected costs when you open a wall, you might find old termite damage or bad wiring. Add 15% to your budget for surprises.
- Temporary kitchen if your extension touches the kitchen, you might be washing dishes in the laundry for a month. Buy a cheap induction hotplate and a bar fridge.
- Neighbour complaints some councils require you to notify neighbours. Be nice. Bake them some cookies.
A good home extension services in Brisbane team will warn you about all this upfront. If they don’t, walk away.
FAQs
1. How long does a typical home extension take in Brisbane?
A rear living pod: 3-4 months. A second storey: 6-9 months. A small bump out: 8-10 weeks. That’s from the day they start digging to the day you move back in.
2. Will my extension need a DA (development application)?
Many rear extensions under 10m deep and within height limits are “self-assessable” no full DA. But second storeys almost always need one. Your builder should check for you.
3. Can I live in my house during the extension?
Yes for rear pods and bump outs, just stay away from the dust zone. For second storeys, it’s pretty miserable. Some families rent an Airbnb for the worst 4-6 weeks.
4. How do I find a reliable home extension builder in Brisbane?
Ask neighbours who’ve done work recently. Check QBCC licence online. Get three itemised quotes if one is way cheaper, run. And ask to see a finished job in person, not just photos.
The bottom line
Moving house is expensive, stressful, and sad if you love your street. Extending isn’t easy it’s still a big project but for many Brisbane families, it’s the smarter move.
You keep your community. You keep your mortgage under control. And you end up with a home that actually fits your life, not someone else’s idea of a dream home. So before you call a real estate agent, call a builder. Ask about a bump out, a rear pod, or going up. You might be surprised how far your block can go.
