House Extensions Brisbane


There is nothing worse than living in a wonderful home that you love, but that isn’t big enough to accommodate your family and your lifestyle. It’s a difficult prospect for homeowners, who may be torn between putting up with the lack of space or begrudgingly moving out and finding a new home. But there is a solution that means you can get that additional space without packing your bags.

Enter: Home Extensions. A home extension involves building outwards from the existing property, in order to create a bigger, more spacious floor plan. It’s a broad umbrella, which could include the construction of entirely new rooms, or renovating and expanding the rooms in the current floorplan. Whatever your home requires, Linear can craft a stunning extension that is perfectly suited to both your needs and the existing home.


At Linear, our extension process is simple. Firstly, we’ll sit down for a chat, asking you to describe your goals and desires, budget and explain what type of style you’re looking to emulate. Once we feel we have a comprehensive understanding of your vision, we’ll draft up a house extension design that achieves your goals and is suitable for your budget. We’ll then take the design to you to discuss in more depth, going back and forth until you’re completely satisfied with the result. Once this has been agreed on, we’ll pull the trigger to finalise the design before lodging all planning applications. When all plans are approved, we can then complete the finishes and specification details prior to proceeding to the build.

What we’re describing here is our simple and stress-free design and construct service, which allows you to design and build your extension project completely in-house. It takes away the extra work of having to find an architect or designer, and means you’ll only be working with one team throughout the whole process. By opting for a design and construct service, you’re more likely to stay on deadline and within budget, as there is one team working in harmony to craft an enviable house extension that will exceed your expectations.


In need of a couple of extra rooms, without the need for a full house extension? Linear can achieve this for you. With special care taken to respect the existing structure, we’ll design and construct a seamless extension that works in complete harmony with your current floorplan. We are experts in ensuring that the extra rooms match up perfectly where possible, with your ceiling height and that structurally, they are a stylish and functional addition to your home.


Are you looking to add a touch of luxury and unique appeal to your current home? Then a bespoke home extension may be the choice for you. This service allows you to create space for special features and elegant selections, without forfeiting the style and charms of your existing home. This type of extension is a great way to add value to your special home, and ensure its live ability for years to come. At Linear, we’re able to help you build entirely new rooms made for leisure – including rumpus rooms, a home theatre or even a custom pool. We can also help you build custom rooms that respond to the challenges of the past two years, such as an office space uniquely suited to the demands of your work. We can also assist in expanding your current bedrooms or kitchen space to make the area more refined, comfortable, and luxurious.

How Much Does A House Extension Cost?

As with any renovation project to an existing home, what it will cost will depend on a multiple factors. The costs will vary between house extensions as no two projects are exactly the same. They’ll be effected by items such as the scale of the extension, the extent of any alteration to the existing structure, and accessibility of the area being extended. Not to mention the level of finishes and specifications of the proposed extension.

The other significant variable is the type of rooms that are planned in the extension. For instance, a house extension that includes a kitchen will be significantly more expensive than a house extension to add a bedroom. Although the two rooms may be similar in area, there is a greater concentration of costs in the inclusion of a kitchen.

For these reasons it pays to be cautious when adopting any square metre rate on a possible extension, and only use the rate as a very rough guide.

The other costing that often gets overlooked is the costs associated with the possibility of relocating during some or all of the build. This can be significant and should be factored within any budget.

Are House Extensions Worth it?

It all depends on what the home owner hopes to achieve, and whether they outweigh the possible disadvantages of undertaking a home extension? Here are four benefits of why a home extension should be considered:

1. Add value to your existing home. A well-considered and designed extension that adds extra rooms or square metres to your house will always increase the value of your home

2. Can be cheaper than buying another house or building new. Extensions generally
represent better value for money than buying or building another, bigger house. You may only want an additional bedroom and bathroom, but the costs of moving house quickly add up – consider agents’ fees, stamp duty, conveyancing costs, not to mention the stress of selling one house, finding another in the right suburb close to schools and your workplace, packing, moving and then unpacking. It’s exhausting just thinking about it!

3. Provide extra space. the possibilities are endless and limited only by your imagination and budget.

4 Adapted to your lifestyle. Extensions can be designed to accommodate your specific needs and wants, lifestyles, etc

Do I Need a Building Permit for a House Extension?

A house extension will require a building approval following the issue of Development Approval (DA) by Brisbane City Council. In cases where the proposed works are DA exempt, the building approval may be self-assessable and formal building approvals may not be required.

A building approval is generally triggered when there are proposed structural changes to a building. When the scope of works for a proposed project fits into Queensland Building Regulations, building approvals may not be required.

How Long do House Extensions Take?

Once again this is hard to quantify as it will depend on the scale, the nature of the project, access and supply chain issues, etc. Generally it tends to be a quicker time frame compared to complete new builds or major renovations.

How Much Value Does a Room Add to a House?

When assessing the increase in value of any home extension, unfortunately there is no standard metric which would value all different types of extensions (ie rooms). It would depend on multiple factors, the most influential would be the state of the local real estate market for comparative properties (post home extension). This would give the best indication of what value your house extension will be worth (factoring in any differences). This exercise should yield a price range of where your extended property will be, from where its value is pre-extension.
