Model builders are responsible for creating three-dimensional visual effects, especially those used in children's programmes screened on television or presented on stage. They also make specialized props and create unique effects which are utilized extensively in variety and drama productions.
The model techniques department has sections that develop and construct special effects such as electronic controls and innovations; puppets and marionettes, including hand, rod and electronically controlled puppets. The property section makes puppet production sets, minute accessories and scenic models such as rural scenes, with lakes, rivers and trees, or urban scenes.
Model builders work in workshops and are in close contact with all departments involved in the production of a television show or play.
