Any woodwork such as doors, trim, crown moulding and so on is generally defined as millwork.
Many of the specific features of the space are created using different types of architectural millwork: doors, window casings, baseboards, mantels, cabinets, 'built-ins', and crown moldings. The materials used in millwork items today are most often graded-lumber, code compliant fasteners, various glasses, and other decorative coatings and finishes. Most millwork building materials can be installed with little or no modification as part of the construction process
