Imbue
Drive through any new estate or architect-designed street in Australia and you will see it: timber on the outside of the house, not just the inside. Timber cladding has moved from farmhouse tradition to one of the defining materials of contemporary Australian architecture.
This guide covers what timber cladding actually is, the styles and species that work in Australian conditions, and the design decisions that separate a good result from a great one.
What Is Timber Cladding?
Timber cladding is a protective and decorative skin of timber boards fixed to the outside (or inside) of a building’s frame. It is not structural — its job is to shield the wall system from weather while giving the building its visible character.
Boards come in a range of profiles that determine how they join and how the finished wall looks. Shiplap profiles overlap so each board sheds water over the one below. Secret-fix profiles hide the fixings entirely, giving clean, uninterrupted lines. Eco Timber’s shiplap cladding is machined in 120mm and 72mm secret-fix profiles from Australian hardwoods.
Cladding is not only an exterior material. The same boards, battens and linings are increasingly used on feature walls and ceilings inside — more on internal timber cladding below.
Why Choose Timber Cladding?
A few reasons keep pulling architects and home builders back to timber:
- Warmth and texture. Timber reads as a natural material at every distance — grain up close, tone and shadow from the street. Render and metal cladding cannot replicate that.
- It ages, rather than dates. Left to weather, hardwood cladding greys off gracefully. Oiled and maintained, it holds its original tone. Either way it develops character rather than looking tired.
- Design flexibility. Boards can run vertically or horizontally, be spaced as battens or packed as solid walls, charred black or left blond. Few materials offer that range from a single product family.
- A renewable envelope. Responsibly sourced timber is a renewable material that stores carbon for the life of the building — see Eco Timber’s approach on the sustainability page.
- Renovation-friendly. Cladding is lightweight relative to masonry and suits both new builds and recladding projects over existing frames.
Popular Timber Cladding Styles
Vertical Cladding
Running boards vertically makes buildings read taller and sharper, which is why vertical shiplap and board-and-batten looks dominate contemporary Australian builds. Vertical boards also shed water efficiently along their length. This style suits clean gable forms and works especially well on double-storey facades.
Horizontal Cladding
Horizontal boards are the classic Australian weatherboard language, reinterpreted with wider hardwood profiles and hidden fixings. Horizontal lines stretch a building visually, settle it into its site, and suit long, low elevations. It is the natural choice when extending a period weatherboard home with a modern addition.
Timber Battens and Slat Cladding
Battens are spaced timber sections fixed over a backing or open frame. They filter light, screen carports and balconies, and add depth to an otherwise flat wall — the shadow lines change across the day as the sun moves. Eco Timber machines timber battens in a range of Australian hardwood sections for facades, screens and ceilings, and also produces 3D and custom cladding profiles for projects that want a sculpted, dimensional surface.
Interior Timber Cladding
Inside, the same materials become lining boards, feature walls and ceilings. Timber overhead or on a hallway wall softens acoustics and brings the material warmth of the exterior through the whole house. Eco Timber’s internal cladding and lining range covers walls and ceilings in solid and recycled hardwoods.
Choosing the Right Timber Species
Species choice drives colour, durability and bushfire performance. Four Australian hardwoods do most of the heavy lifting in cladding:
Spotted Gum. Rich brown tones with distinctive wavy grain. Naturally durable and one of the species recognised for use in bushfire-prone areas, it is arguably the most popular cladding hardwood in the country.
Blackbutt. Pale, even, honey-toned boards that suit lighter contemporary palettes. Like Spotted Gum, it is one of the hardwood species recognised for BAL-29 bushfire applications.
Ironbark. One of the hardest and most durable commercial timbers in Australia, in deep red-brown tones. A heavyweight choice, literally and figuratively, for exposed coastal or high-wear locations.
Messmate. Warm straw-to-brown tones with plenty of figure, widely loved as a recycled timber. Better suited to protected and interior applications than fully exposed walls.
If your site is in a designated bushfire zone, check the BAL rating requirements with your certifier before locking in a species — it will narrow your options quickly.
Charred Timber Cladding (Shou Sugi Ban)
Charring deserves its own section, because it changes both the look and the performance of the board.
Shou sugi ban is a Japanese technique in which the face of each board is deliberately burnt to a deep charcoal black. The carbonised surface is naturally resistant to UV, moisture and insects, so the finish is more than an aesthetic decision — the char is doing protective work.
The look is dramatic: matte black walls that shift with the light and contrast beautifully with raw timber, stone and greenery. It has become a signature of contemporary Australian architecture, particularly on bold, sculptural forms.
Eco Timber runs its own charring line — one of the first commercial operations of its kind in Australia — producing charred timber cladding in dense hardwoods including Ironbark and Spotted Gum for BAL-29 applications. If you want to understand the technique more deeply, the team has written about how shou sugi ban enhances the longevity of timber.
Timber Cladding Design Ideas
Some directions that are working well on current Australian projects:
- Timber and stone. Charred or dark-stained cladding against a stone base grounds a building in its landscape — a pairing that suits bush and coastal sites equally.
- Timber and concrete. Warm hardwood boards soften off-form concrete. The two materials make each other look better.
- Timber and glass. Battens across glazing filter western sun while keeping views, turning a practical shading requirement into the facade’s best feature.
- Mixed orientation. Vertical boards on the upper storey with horizontal boards or battens below breaks up a large facade and defines the building’s zones.
- Inside-out continuity. Running the same species from an exterior wall through a window line into an interior ceiling blurs the boundary between inside and out — a hallmark of biophilic design, which the Eco Timber team explores in the role of timber cladding in biophilic design.
What to Consider Before You Buy
A short checklist before you commit:
- Exposure. North- and west-facing walls cop the most UV in Australia. Expect more maintenance there, or choose charred or pre-weathered finishes that handle exposure gracefully.
- Bushfire rating. Confirm your site’s BAL requirement and match species and system to it.
- Fixing system. Secret-fix profiles cost a little more but remove visible nail heads from the finished wall.
- Finish and maintenance. Decide upfront: naturally weathered grey, regularly oiled original tone, or charred. Each has a different maintenance rhythm.
- Coverage and waste. Order on actual coverage (profile cover width, not board width) and allow for offcuts on complex facades.
- Compliance. Cladding must be installed over a compliant wall wrap, cavity and flashing system — the boards are only as good as what is behind them.
