Kitchen joinery is where most of the cost, complexity and defect risk sit in a residential fit-out. A thorough specification protects both quality and budget, and it is the clearest way to compare quotes fairly. Here is what a robust kitchen cabinetry specification should cover.
1. Carcass Substrate
The carcass (the box structure) determines durability and moisture performance.
Melamine-faced particleboard: the economical mainstream option for apartments and project homes
Moisture-resistant (MR) MDF or particleboard: preferred around sinks, dishwashers and wet areas
Plywood: superior screw-holding and moisture tolerance, used in premium and high-wear applications
Thickness: 16mm and 18mm are standard, and thicker substrates are used for long spans and heavy loads
State the substrate, thickness and edge treatment in the specification. "Standard board" is not a specification.
2. Formaldehyde Emission Class
Australian board products are classified by formaldehyde emission under AS/NZS 1859, commonly E0, E1 and E2, with E0 the lowest emission. Many Green Star and developer ESG requirements call for low-emission board, so specify E0 (or E1 at minimum) and request supplier test documentation. This is especially relevant for imported board, where the classification system used on the factory's certificates may differ and needs to be mapped to the Australian classes.
3. Door and Panel Finishes
Common options include:
High-pressure and low-pressure laminates: durable and cost effective
Thermofoil or vinyl-wrapped MDF: seamless profiles at moderate cost
Painted (2-pack polyurethane) MDF: premium, repairable finish
Timber veneer: natural, premium look
Acrylic and gloss panels: high-end contemporary finish
See our comparison of veneer, solid timber and laminate for the trade-offs.
Specify finish codes by supplier reference, gloss level, edge profile (laser, ABS or PUR edge-banded) and grain direction.
4. Hardware
Hardware quality drives how a kitchen feels in daily use and how it performs over time.
Hinges: soft-close concealed hinges from recognised brands, with a specified opening angle
Drawer systems: full-extension soft-close runners with a rated load capacity
Lift-up and pocket systems for overhead and appliance cabinets
Handles and push-to-open: confirm compatibility with door thickness and finish
Always specify brand and model, or an explicit "approved equivalent" clause with testing criteria. This prevents silent substitution with cheaper hardware during production.
5. Benchtops and Stone Interfaces
Even when the benchtop is supplied by others, joinery tolerances determine whether it fits:
Specify cabinet levelness and tolerance for stone or engineered stone installation
Coordinate cut-outs for sinks, cooktops and tapware
Confirm overhang and support requirements for waterfall edges and thick benchtops
6. Appliances and Services Coordination
Provide the appliance schedule and dimensions before the shop drawings are finalised. Include ventilation, clearances and service penetrations. Late appliance changes are a leading cause of remakes.
7. Tolerances and Quality Criteria
A good specification defines acceptable tolerances for:
Door gaps and alignment
Edge-banding quality
Colour and grain consistency between panels
Surface defects visible at normal viewing distance
Defining these upfront avoids subjective disputes at handover.
8. Packaging and Delivery Condition
For offshore supply, specify whether cabinetry is delivered flat-packed or pre-assembled, how panels are protected, and how items are labelled by unit and room. Flat-packing cuts freight cost significantly (see our container shipping guide), but requires competent assembly on site.

The Bottom Line
The cheapest quote is rarely the lowest-cost kitchen. A specification that names substrate, emission class, finishes and hardware gives you comparable quotes, predictable quality and fewer defects at handover.
