How is custom cabinetry priced — by square metre, projected area or per unit?

We quote per item against the approved shop drawing, with a clear breakdown of carcass, doors, hardware, accessories, packing and freight. Per-square-metre or projected-area pricing looks simple but hides the variables that actually drive cost: internal fittings, door style and hardware. Our quotations are itemised precisely so you can compare properly and adjust scope knowingly.
