Planning a Home Extension? Here’s What You Need to Know
Before you start knocking down walls for your home extension, here’s what you need to know to ensure a smooth and stress-free build.

Thinking of adding a bit more space to your home? Whether you’re welcoming a new family member, craving a bigger kitchen or a pool house, or finally setting up that dream home office, a home extension is a brilliant way to add space and boost property value.
But before you start knocking down walls for a home extension, here’s what you need to know to ensure a smooth and stress-free build.
1. Know What You Want (and Need!)
Before you even think about calling in the pros, have a clear vision of what you want. Ask yourself:
-
What’s the main purpose of the extension?
-
How much additional space do you need?
-
What’s your budget?
-
Will it match the existing style of your home?
Sketch out a rough idea or gather inspiration from Pinterest, Instagram, or home renovation shows. Having a clear plan will help tradies understand your vision and give you accurate quotes.
2. Check Council Regulations and Permits
Depending on where you live, council approval might be required before you start building. Each state and council has different regulations, so it’s worth checking in with your local authority. Some smaller extensions or renovations might fall under exempt development, meaning you won’t need approval, but it’s always best to double-check before starting work.
A reputable builder or architect can help guide you through the approval process, ensuring everything is above board.
3. Set a Realistic Budget (and Add a Buffer!)
Home extensions can be a big financial commitment, so planning your budget wisely is key. Costs will vary based on size, materials, and labour, but talking to a trusted home renovator or builder can help give you insight into how much your project may set you back.
A common mistake homeowners make is underestimating costs. Hidden expenses such as council fees, site preparation, or unexpected structural issues can add up quickly. To be safe, add at least 10-20% to your budget as a buffer for any surprises.
4. Find the Right Tradies for the Job
A home extension isn’t a one-person job. You’ll likely need a team of tradies, including:
-
Architects or designers to draw up the plans
-
Builders to bring those plans to life
-
Electricians for wiring and lighting
-
Plumbers if your extension includes a bathroom or kitchen
-
Plasterers and painters to finish it all off nicely

5. Think About Timeframes and Disruptions
Home extensions don’t happen overnight. Depending on the complexity of the build, it could take anywhere from a few weeks to several months. Be prepared for some disruptions to your daily routine.
If you’re extending key areas like the kitchen or bathroom, you might need a temporary setup. And if major structural work is involved, moving out for a bit could be the best option.
6. Choose Materials Wisely
Your extension should blend seamlessly with your existing home, so choosing the right materials is crucial. Consider:
-
Bricks or cladding that match your home’s exterior
-
Flooring that flows from room to room
-
Insulation to keep your home comfortable year-round
Not sure what works best? A builder or designer can offer advice on materials that suit your home, climate, and budget.
7. Plan for Energy Efficiency
A well-designed extension isn’t just about space; it should also be energy-efficient. Think about:
-
Installing double-glazed windows to reduce heat loss
-
Using energy-efficient lighting
-
Positioning windows to take advantage of natural light and ventilation
-
Adding solar panels if you’re making major upgrades
Small changes can lead to big savings on energy bills in the long run.
8. Don’t Forget About Storage!
More space doesn’t always mean more storage—unless you plan for it! Built-in shelves, clever cabinetry, and hidden storage solutions can keep your new space tidy and functional.
9. Communicate Clearly with Your Tradies
Good communication is key to a successful renovation. Set clear expectations from the start, get everything in writing, and check in regularly to ensure the project is on track.
Using a platform like ServiceSeeking.com.au makes it easy to stay connected with tradies, track progress, and ensure everything goes smoothly.
