Millwork vs. Casework
People use these terms loosely, and specifications often mix them, so here is how the trades usually separate them.
Millwork is wood product made in a mill: doors, door and window casings, baseboards, crown moulding, wainscoting, mantels, stair parts and decorative trim. It is the architectural detail that gives a room its character.
Casework means boxes and storage: cabinets, shelving units, counters and built-in units. It is the cabinetry that holds things, and it is built from sheet material and hardwood into finished, installed units. In commercial projects, casework and architectural woodwork are often specified together in a single division, so one shop may do both.
Why does the difference matter? When you are comparing quotes, ask exactly what is included. A kitchen may be priced as casework only, with trim, panelling and mantels as separate millwork. For commercial and large residential jobs, drawings and specs often call out both, and clear scope avoids surprises.
In practice the two overlap. A built-in bookcase is casework framed with millwork trim, and a reception desk is casework wrapped in architectural panelling. A custom shop that builds both keeps the details consistent from one to the next.
