Joinery is where a new home either sings or sags. You can pour a perfect slab, frame it dead square and still end up with a kitchen that feels cheap because someone rushed the cabinetry. Built-in wardrobes, kitchen carcasses, laundry benches, window seats, the bookshelf under the stairs: this is the stuff you touch every single day.
And yet joinery is often the last thing homeowners think about, usually somewhere around the point the roof goes on. By then, the budget is tight and the lead times are brutal. Talk to any builder in Melbourne or Brisbane and they’ll tell you the same story: the joinery decisions made too late are the ones that hurt.
Start the Conversation Earlier Than You Think
Custom joinery should be locked in during design documentation, not after frame stage. There’s a practical reason for this. Joinery dictates plumbing rough-ins, power point locations, appliance clearances and sometimes structural nogging for wall-hung units.
A 900mm freestanding oven versus a 600mm built-in changes your cabinet run. A wall-hung vanity needs blocking behind the plasterboard. Miss these and you’re cutting holes in finished walls, which nobody enjoys paying for.
Lead times matter too. Most custom joinery shops in Australia are quoting six to ten weeks from final measure to delivery, and that blows out over summer when everyone shuts down for three weeks in January. Factor it in.
Get Your Measurements From the Real Thing
Never let a joiner quote from plans alone for the final build. Plans lie. Walls bow, floors dip, and a 3000mm opening on paper often measures 2987mm in the flesh. A proper check measure after plaster and before tiling is non-negotiable. Good joiners insist on it.
Materials Decide Whether It Lasts
This is where the money goes, and where the shortcuts show up in five years. Standard MDF with melamine facing is fine for a wardrobe interior. It’s a poor choice for a laundry cabinet that cops splashes from a front loader, because once the edge swells, you’re done.
For anything near moisture, or anything carrying real weight, structural plywood sheets are the smarter play. Ply holds screws better, resists sagging across long spans and doesn’t turn to porridge when it gets wet. A 18mm hoop pine ply shelf will carry a full run of hardcover books across 900mm. The same span in 16mm particleboard will develop a permanent smile.
Some practical material notes worth raising with your joiner:
Kitchen carcasses: 18mm moisture-resistant board minimum, with ABS edging rather than PVC iron-on
Exposed shelving: plywood with a clear finish, showing the edge grain, has been popular for a decade and still looks current
Wardrobe internals: white melamine is genuinely fine here and saves money for where it counts
Vanities: marine-grade ply or solid timber, never standard MDF, regardless of what the cheap quote says
Doors and drawer fronts: two-pack polyurethane for a seamless look, timber veneer if you want grain
Hardware Is Not the Place to Save $400
Drawer runners and hinges get used thousands of times. Blum and Hettich soft-close runners cost more upfront, maybe $40 to $60 a drawer against $15 for generic gear, but they come with lifetime warranties and they don’t develop that gritty rattle after two years.
On a 30-drawer kitchen, going premium might add $1,200. Against a $40,000 kitchen, it’s noise. Against the annoyance of a drawer that sticks every time you reach for a teaspoon, it’s a bargain.
Think About the Bits Nobody Sees
Ask about adjustable legs versus fixed plinths. Ask whether the joiner scribes to the wall or relies on silicone. Ask how the toe kick is finished. These small details separate joinery that ages well from joinery that starts gapping the first time the house moves through a hot summer.
Managing the Relationship With Your Builder
Decide early whether joinery sits inside the builder’s contract or as a direct engagement. Both work. Both have traps.
Inside the contract, you pay a builder margin, often 15 to 20 per cent, but the builder owns the coordination and the defect liability. Direct engagement saves that margin but you become the project manager, chasing access dates and sorting out who’s responsible when the joinery arrives before the floors are sealed.
For most first-time builders, keeping joinery in the contract is worth the premium. If you’ve done this before and you have a joiner you trust, go direct.
A Few Hard-Won Lessons
Order 10 per cent more handles than you need. They discontinue faster than you’d believe.
Photograph every wall before plaster goes on, with a tape measure in frame. You will need those photos.
Sign off on a full set of shop drawings, not a rendered image. Renders hide gaps. Drawings show dimensions, and dimensions are what get built.
Good joinery doesn’t announce itself. It just fits, opens smoothly and still looks sharp when you sell the place in fifteen years. Spend the time on it now.
