Timber vs Light Gauge Steel Framing: Why Most Builders Still Default to Timber

What the material choice really means for build quality, cost and long-term performance
When planning a new home, many clients assume the structural frame is a purely technical decision — something the builder automatically selects. In reality, the choice between timber framing and light gauge steel framing plays a critical role in build quality, construction accuracy, ongoing maintenance, and long-term performance.
As more homeowners research timber vs light gauge steel framing, a common question emerges:
If light gauge steel frames perform so well, why do most builders still default to timber frames for houses?
Timber framing as the residential default
In Australian residential construction, timber frame houses remain the dominant choice. Most builders, carpenters and subcontractors are trained primarily in timber framing systems, and their pricing structures, construction programs and detailing methods are built around timber construction.
As a result, timber is often selected not because it performs best in every scenario, but because it is the default residential framing system.
Timber frame construction allows:
Greater flexibility for on-site changes
Tolerance for minor set-out inaccuracies
Easier last-minute adjustments
Familiar workflows for residential builders
For builders operating on tight margins, timber frame construction offers convenience and predictability — even if it comes with long-term compromises.
Light gauge steel framing: performance-driven construction
Light gauge steel framing behaves very differently from timber.
Unlike timber, steel framing for residential buildings:
Does not shrink, warp or twist
Is unaffected by moisture or humidity
Moves only with temperature, in a predictable manner
Remains dimensionally stable over the life of the building
These characteristics make light gauge steel frames particularly suitable for:
Architecturally designed homes
Large open-plan layouts and long spans
High-end finishes requiring tight tolerances
Homes with extensive glazing
Projects prioritising durability and longevity
However, steel framing also requires a higher level of planning and coordination than traditional timber construction.
Why many builders hesitate to use steel frames for houses
Despite its advantages, many residential builders remain cautious about steel framing vs timber framing. This hesitation is rarely about performance and more about process.
1. Familiarity and perceived risk
Builders are comfortable managing known timber-related issues such as shrinkage and seasonal movement. Steel framing, while highly predictable, is often seen as unfamiliar territory — particularly where subcontractors lack experience in light gauge steel residential construction.
2. Upfront cost focus
While steel frames can reduce long-term maintenance and defect risks, steel frame houses can carry slightly higher upfront costs. Many builders focus on initial construction cost rather than whole-of-life performance.
3. Reduced on-site flexibility
Steel framing requires earlier design decisions and precise coordination. Unlike timber framing, changes are not easily absorbed during construction — which challenges traditional residential workflows.
4. Higher construction discipline
Steel framing exposes poor coordination. Slab tolerances, set-out accuracy, and documentation quality all matter. Timber framing can conceal minor errors; steel framing cannot.
Timber vs steel framing myths: noise and cracking
One of the most common concerns raised in discussions about steel frame vs timber frame houses relates to noise and cracking. In practice, these issues are not caused by the steel frame itself.
When problems occur in steel-framed houses, they are typically linked to:
Poor detailing at material junctions
Incorrect plasterboard fixing methods
Lack of isolation between framing and linings
Inexperienced installation
A properly detailed light gauge steel frame house is no noisier than a timber-framed home and often performs better over time due to its dimensional stability.
By contrast, timber framing in Melbourne’s climate continues to respond to seasonal moisture changes, which can result in long-term movement, shrinkage, and minor cracking.
What the framing choice means for homeowners
Neither system is inherently right or wrong. Both timber framing and steel framing can deliver excellent outcomes when designed and constructed properly.
The key difference lies in performance over time:
Timber frame houses offer familiarity and flexibility, but continue to move with moisture and seasonal change.
Light gauge steel frame houses offer precision, stability and durability, but require better planning and coordination upfront.
The most important factor is that the framing system is chosen deliberately, based on the project’s design intent, site conditions, budget and long-term expectations — not simply because it is the default option.
The architect’s role in framing selection
As architects, our role is to guide clients through informed decisions about residential framing systems. In some projects, timber frame construction is entirely appropriate. In others — particularly where precision, fire resistance, durability or complex geometry are involved — light gauge steel framing can offer clear advantages.
The best homes are not shaped by habit. They are shaped by intention, understanding and coordination.

This article is intended as general information only. The suitability of timber framing or light gauge steel framing varies depending on site conditions, design complexity, budget, local regulations, builder capability and project-specific requirements.
Material selection should always be made in consultation with a qualified architect, engineer and builder, and in accordance with relevant Australian Standards and statutory requirements.
