Thinking about raising a Queenslander? Learn when Brisbane town planning approval may be needed and why the building core matters.
Raising and building under a Queenslander is one of the most common ways Brisbane homeowners create more space while keeping the character and charm of an older home.
It can be a great option if you want extra bedrooms, more living space, storage, parking or a better connection to the backyard. However, if your house is affected by Brisbane’s Traditional Building Character overlay, it is important to check the town planning requirements before the project gets too far along.
Some raise-and-build-under projects may be accepted development. Others may require a development application to Brisbane City Council. The answer depends on the site, the age of the house, the proposed works, the building height, the relevant overlays and whether the new work stays within the existing building core.
Why raise and build under a Queenslander?
Queenslanders were often built with elevated timber floors, generous undercroft areas and a lightweight construction style. That can make them well suited to being raised and built under.
For many homeowners, this approach allows them to keep the original character house while making it more practical for modern family living.
Raising and building under can help create:
- additional bedrooms or bathrooms;
- a second living area;
- more storage;
- improved car parking;
- better access to the backyard;
- a more flexible lower level; and
- a larger home without demolishing the original house.
It can be a really good outcome when done well. The key is making sure the design works not only from a building perspective, but also from a town planning perspective.
Do I need town planning approval?
You may need town planning approval to raise and build under a Queenslander, particularly if the house is pre-1947 and located within the Traditional Building Character overlay.
In some circumstances, raising a dwelling house and enclosing underneath may be accepted development. However, that usually depends on the proposal meeting specific requirements. These can relate to building height, neighbourhood plan requirements, demolition, the location of the work and how the proposal affects the character of the house.
This is where many people get caught out. A project might look like a normal renovation, but still trigger town planning approval because of the age of the house, the overlay mapping or the extent of demolition involved.
It is also important to remember that building approval and town planning approval are separate. A building certifier may be involved in the structural and building approval side of the project, but that does not automatically mean the town planning requirements have been dealt with.
Why the building core matters
The building core is an important concept for raise-and-build-under projects, particularly within the context of character houses in South-East Queensland.
In simple terms, the building core generally refers to the main enclosed part of the existing house. It is usually the central part of the dwelling, rather than open verandahs, external stairs, decks, carports or later additions.
For character houses, Council is often interested in whether new work stays within the original or existing form of the dwelling, and whether the proposal protects the way the house presents to the street.
Building underneath within the existing building core may be more straightforward than extending beyond it. For example, enclosing under the main body of the house may have a different planning outcome to building new enclosed areas beyond the original side or front form of the dwelling.
That does not mean work outside the building core is impossible. It just means the planning requirements need to be checked more carefully. The location of the work, visibility from the street, amount of demolition, existing character features and the age of different parts of the house can all affect whether approval is required.
What Council may look at
For a raise-and-build-under project in a character area, Council may consider several planning issues.
Building height
Raising a Queenslander can increase the overall height of the building. If the final height does not meet the relevant requirements, town planning approval may be triggered. Height should be checked early, especially if the design includes a fully built-in lower level, higher ceilings underneath or changes to the roof form.
Demolition and original fabric
Even if the house is being retained, the project may still involve demolition. This could include removing stairs, walls, windows, verandah elements, battening, lower-level areas or later additions. Demolition of original pre-1947 fabric can be more sensitive than demolition of newer alterations. If the house is pre-1911, additional care may be needed.
Street appearance
Brisbane’s character controls are often focused on protecting the traditional appearance of older houses, especially as viewed from the street. A lower-level enclosure that sits neatly under the house and keeps the original upper-level character visible may be easier to support than a design that significantly changes the front presentation of the home.
Verandahs, stairs and external details
Queenslanders often rely on verandahs, stairs, fretwork, balustrades, windows, roof form and lightweight detailing for their character. Changes to these elements can affect how the proposal is assessed, particularly where the work is visible from the street or involves original parts of the house.
Other overlays
The Traditional Building Character overlay may not be the only planning issue on the site. Flooding, overland flow, heritage, neighbourhood plans, biodiversity and other overlays may also affect the approval pathway. This is why each property needs to be checked individually.
Common mistakes to avoid
One common mistake is assuming that raising a Queenslander is automatically accepted because similar homes nearby have already been raised. Those projects may have had different site conditions, different approval pathways or earlier approvals under different rules.
Another mistake is designing the whole project before checking the planning requirements. This can lead to redesign costs if the proposal does not meet the relevant character, height or building core requirements.
It is also worth being careful with demolition. Removing original features before understanding whether approval is required can create serious issues and may affect the ability to justify the proposal later.
How a town planner can help
A town planner can help confirm whether your raise-and-build-under project needs a development application.
This usually involves checking:
- Brisbane City Plan 2014 mapping;
- whether the Traditional Building Character overlay applies;
- the likely age of the house;
- whether the house may be pre-1911;
- the existing building core;
- what parts of the house are proposed to be demolished;
- final building height;
- neighbourhood plan requirements;
- other overlays affecting the site; and
- whether the work may be accepted development.
If a development application is required, a town planner can prepare the planning report, respond to the relevant assessment benchmarks and help coordinate the application with your designer, builder or certifier.
Getting this advice early can make the process much smoother and help avoid unnecessary redesigns or delays.
Conclusion
So, can you raise and build under a Queenslander in Brisbane? Often, yes – but the approval pathway depends on the property and the details of the proposal.
The main things to check are whether the house is affected by the Traditional Building Character overlay, whether it is pre-1947 or pre-1911, whether demolition is involved, whether the final building height complies, and whether the new work stays within the existing building core.
