House Renovations and Extensions in Brisbane: Expanding Your Home the Right Way.
Need more space but don’t want to move? A house extension could be the answer. In Brisbane, more homeowners are choosing to expand rather than sell, making the most of their property and location. Whether you’re adding a new bedroom, living area, or an extra level, a well-planned extension can completely transform your home.
Why Choose House Extensions?
House extensions are ideal for growing families, lifestyle upgrades, or creating rental potential. Instead of uprooting, you can stay in the area you love while getting the extra room you need. Brisbane’s character homes, sloping blocks, and zoning rules make Renovations and Extensions a smart alternative to rebuilding.
With over 30 years of building experience in Queensland, Jensen Constructions understands the local landscape and regulations. We know how to design extensions that are functional, compliant, and add real value.
How Close to My Neighbour’s House Can I Build an Extension?
In Brisbane, how close you can build to your neighbour’s property depends on the zoning of your land and the height of your extension. As a general rule:
- If the wall is up to 4.5m high, the minimum boundary setback is 1.5m
- For walls over 4.5m but not exceeding 7.5m, the setback increases to 2m
- If the wall exceeds 7.5m, the setback must be 2m or more, depending on council assessment
These rules can vary based on overlays and the Brisbane City Plan, so always check with a qualified builder or town planner before starting. Our team ensures all Renovations and Extensions meet local guidelines and building codes.
Can an Extension Be Bigger Than the Original House?
Yes, in some cases an extension can be larger than the original structure. It depends on factors like:
- Total lot size
- Zoning and overlays
- Maximum site cover allowed (usually around 50% in residential zones)
- Height restrictions (typically capped at 9.5m in most Brisbane suburbs)
For example, a small post-war home on a large block in Ashgrove may allow for a large, modern extension that doubles your living space. A detailed site analysis is essential. Our team at Jensen Constructions handles this as part of our Our Services, so you don’t have to worry about compliance.
What Is the Most Expensive Part of a House Extension?
The cost of an extension can vary widely, but typically the most expensive parts are:
- Structural Work – Adding new foundations, beams, or removing load-bearing walls can add significant cost
- Plumbing & Electrical – Connecting new bathrooms or kitchens requires complex work and inspections
- Second-Storey Additions – Going up adds design, engineering, and scaffolding costs
- Material Choices – High-end finishes or custom features quickly raise the budget
We guide you through these decisions to balance quality with cost. Every project under Renovations and Extensions is scoped and priced clearly, so you know where your investment is going.
Making the Most of Your Brisbane Extension
Brisbane’s climate and lifestyle offer unique design opportunities. Here are a few ideas to make the most of your space:
- Open-plan kitchen and dining for family connection
- Outdoor alfresco living that flows from your main living area
- Master suite with walk-in robe and ensuite for privacy
- Home office or studio space for remote work or hobbies
These features not only improve liveability but add long-term value to your property.
