Millwork is a broad term for custom wood (and mixed-material) building components made to a specific design — everything from reception desks and paneling to trim and feature walls. Casework is a subset of millwork: the boxes and cabinets that store or display things. Cabinetry usually means casework built for storage specifically.

The plain-English version

• Millwork = the umbrella. Any custom-fabricated, design-specific interior woodwork and built components — curved feature walls, reception desks, wall paneling, columns, trim, displays, plus the cabinets. If it’s custom-made to an architect’s drawing, it’s millwork.
• Casework = the cabinet boxes within that scope — standardized or semi-custom carcasses used to store, display, or serve: nursing stations, serveries, retail display cases, back-of-house cabinetry. Casework is millwork, but not all millwork is casework.
• Cabinetry = casework focused on storage — the drawers-and-doors boxes. In everyday use “cabinetry” and “casework” overlap; casework is the more technical, commercial term.

Why the distinction matters on a project

• Specification & cost: casework is often more modular and repeatable (cheaper per unit at volume); bespoke millwork features cost more but define the space. See what commercial millwork costs for the full breakdown.
• Standards: architectural woodwork is built to defined quality grades (the AWI standards define Economy, Custom, and Premium). Knowing whether you’re speccing feature millwork or production casework helps match the grade — and the budget — to the need.
• Who builds it: a full-capability shop fabricates both across every material under one roof, so a project’s feature millwork and its casework stay consistent in finish and quality.

A quick example

In a retail store: the curved illuminated feature wall and reception desk are millwork; the display cases and stockroom cabinets are casework; the drawer units inside the cash wrap are cabinetry. All three, on one project, from one fabricator.

So which do you need?

Most commercial and retail projects need both millwork and casework — the statement pieces that shape the brand experience, and the functional cabinetry that makes the space work. The advantage of a single manufacturer is that every element matches and the whole package is one accountable scope.

DNS Industries fabricates commercial millwork and casework — feature pieces to functional cabinetry — engineered, machined, and finished under one roof in Vaughan, Ontario.

Frequently asked questions

What is the difference between millwork and casework?

Millwork is the broad umbrella term for custom, design-specific woodwork and built components — feature walls, reception desks, paneling, trim, displays, and cabinets. Casework is a subset of millwork: the cabinet boxes used to store, display, or serve, such as nursing stations, display cases, and back-of-house cabinetry.

Is cabinetry the same as casework?

Cabinetry usually means casework built specifically for storage — the drawers-and-doors boxes. In everyday use the terms overlap; casework is the broader, more technical commercial term.

Do I need millwork or casework for my project?

Most commercial and retail projects need both — the feature millwork that shapes the brand experience and the functional casework that makes the space work. Using one manufacturer keeps every element consistent in finish and quality.
