Wood Is Alive, and It Has Opinions
Timber swells, shrinks and occasionally sulks with the weather. A short guide to joinery that makes room for it.

Timber isn’t just a finish. It keeps reacting to the weather long after it’s been cut and oiled.
It swells in a wet week and shrinks in a dry one, mostly across the grain. On the coast, a solid tabletop can move several millimetres in a year.
Give it room
Good joinery lets wood move where it can’t do harm. Panels float in their frames, tabletops sit on slotted brackets, and shadow gaps act as quiet pressure valves.
Choose the right cut
Quarter-sawn timber moves less and stays flatter. Its straight, calm grain makes it our first choice for long runs of panelling.
Pick the species for the job
Oak is stable and takes oil well. Walnut works beautifully but dents easily. Spotted gum and blackbutt handle floors and decks. Ironbark belongs on steps and thresholds.
Let the finish breathe
Thick coatings crack where the wood moves underneath. Oils and waxes let it keep working, and they can be refreshed in one spot.
Wood isn’t difficult. It just has a temperament, and good design makes room for it.
