Gold Coast Home Extensions
Running out of room doesn’t always mean you need to move. At Michael Duncan Constructions Pty Ltd, we build practical home extensions across the Gold Coast that help families stay where they are while gaining the extra space they need. Whether it’s expanding a living area, adding bedrooms or improving how your layout works, we help you make better use of your property.
Every extension begins with a conversation about how you want the new space to function. We look at how the addition will connect with the existing home and how it will work day to day.
If you're thinking about home extensions, give us a call on 0402 980 897 and we’ll talk through the possibilities.

Frequently Asked Questions
Planning home extensions often raises important questions about design, approvals and timelines. Here are answers to common questions homeowners ask.
We want to extend our house. What order do we need to do things in?
Start by having house plans drawn up. If structural changes are involved, engineering plans may also be required. Once these are ready, we can review the plans and provide a quote.
Do we have to move out?
In many cases it isn’t necessary to move out during an extension or addition build. We aim to minimise disruption and keep the process as manageable as possible while work is underway.
How long will it take to complete our extension?
The timeframe depends on the size and complexity of the extension. Once we’ve prepared your quote and reviewed the plans, we’ll be able to provide a timeline for the project.
What could add value to my home?
Closing in garages or building carports to the boundary can add both space and value to your home. Adding a second storey is another option that can significantly increase living space and property value.
Do I need planning permission for a home extension?
Most home extensions require approval from your local council, particularly if structural changes are involved or if the work affects the building footprint, height or boundaries.
It’s best to check early in the process to avoid delays later. A draftsperson or builder familiar with local requirements can usually assist with the approval process.
Is a second storey addition worth it?
Yes, especially on smaller blocks where extending outward isn’t practical. A well-designed second storey can significantly increase your living space without sacrificing your yard.
It can also add long-term value to your property when designed and built correctly.
Additions That Improve How You Live
A well-built extension should feel like part of the original home, not something added later. We design and build additions that blend naturally with your existing layout while creating extra space that works for everyday living.
Some of the extensions and additions we build include:
- Living & entertaining space extensions
- Kitchen, bedroom & bathroom extensions
- Second storey additions
- Granny flats & teenage retreats
- Entertainment areas & outdoor living spaces
- Garages, sheds & pool enclosures
We also help rework underused rooms or unused areas of your property to create practical new spaces. Throughout the project, we coordinate trades carefully and keep you informed so your extension progresses smoothly and blends seamlessly with the rest of your home.
