Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did the rougher work such as framing, but today many other materials are also used[1] and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry.
It is more correctly used to describe the skill involved in first fixing of timber items such as construction of roofs, floors and timber framed buildings, i.e. those areas of construction that are normally hidden in a finished building.
