Renovating a Large Home in Brisbane
Updated: 9 hours ago
A structured approach to complex renovation projects
Larger renovation projects involve more than just design—they require clear planning, coordination and early decision-making to achieve a successful outcome.
We work with homeowners undertaking significant renovations and extensions where design, cost and buildability all need to be carefully aligned.
Why Larger Renovations Require a Structured Approach
As project scale increases, so does complexity:
Greater structural and planning considerations
Higher construction costs and risk
More decisions impacting budget and outcome
Without a clear process, these projects can quickly become inefficient and unpredictable.
Is your house affected by character controls?
Many older Brisbane homes are affected by Brisbane City Council's Traditional Building Character Overlay (TBCO).
These controls can affect demolition, alterations and additions to an existing house. They can also influence where additions are located and how they relate to the original building and streetscape.
This doesn't mean a character house can't be substantially altered or extended. It means the planning requirements need to be understood early so you're not developing a design around an option that may be difficult—or impossible—to approve.
Should you raise, extend or reconfigure?
This is one of the biggest early decisions.
Raising can provide a substantial amount of additional floor area without increasing the building footprint. On other sites, a rear extension may provide a simpler and more economical solution.
Sometimes the existing house already contains enough floor area and the real problem is how that space is organised.
Before deciding, it's worth comparing the alternatives against:
the accommodation you actually need;
orientation and natural light;
connection to outdoor areas;
privacy and neighbouring properties;
existing structure and floor levels;
planning requirements; and
construction cost.
A larger renovation isn't necessarily a better renovation.
What will it cost?
Queenslander renovation costs can vary considerably.
Two projects providing a similar amount of additional floor area can have very different costs depending on the amount of existing building being altered, structural work required, access, site conditions and level of finish.
Raising a house, excavating underneath it, retaining, replacing services or substantially modifying existing structure can add costs that aren't apparent from floor area alone.
This is why we prefer to consider design and budget together from the beginning, rather than completing a design and only then discovering what it is likely to cost.
How do you make the old and new work together?
A successful Queenslander renovation doesn't necessarily mean reproducing the original architecture.
Contemporary additions can work very well with traditional houses. What matters is that the relationship between old and new is considered—the proportions, scale, materials, roof forms, openings and transition between spaces.
The objective should be a home that feels coherent rather than added-on, while allowing the new work to respond to contemporary living.
Should you renovate, rebuild or move?
Sometimes the early investigation reveals a more fundamental question.
If achieving the required accommodation involves extensive structural work, compromises to the existing house or a construction cost approaching that of a new home, it is worth asking whether renovation is still the best investment.
For some properties, renovation clearly makes sense. For others, rebuilding or even moving may deserve consideration.
That decision is much easier to make before significant money has been spent on detailed design and documentation.
Start by defining the project
Before committing to detailed design, we use a four-step Project Definition process to understand the property, your objectives, the available options and the likely budget.
It begins with preliminary research into the property and progresses through an on-site Needs & Options Review, concept design and budget review.
The aim isn't simply to start drawing. It's to establish what you should be designing in the first place.
