Millwork

This article is about building materials. For millwork used in mechanical power systems, see Line shaft. For the song by James Taylor, see Millwork (song).
Traditional interior millwork examples: note the wall covers, as well as the door and window trim, are all custom-styled to complement the central focus point of the room—the fireplace mantle.

Millwork is historically any wood-mill produced decorative material used in building construction. Stock profiled and patterned millwork building components fabricated by milling at a planing mill can usually be installed with minimal alteration. Today, millwork may encompass items that are made using alternatives to wood, including synthetics, plastics, and wood-adhesive composites.

Often specified by architects and designers, millwork products are considered a design element within a room or on a building to create a mood or design theme. Millwork products are used in both interior and exterior applications and can serve as either decorative or functional features of a building.
