The set designer works closely with the director to interpret the play through the set. The set influences key elements like place, movement, sightlines, and symbolism. There are different types of sets including rostra and levels, box sets, swivel sets, and fixed sets. When designing a set, the designer must consider the period, place, movement opportunities, levels, and symbolic elements of the piece. The design brief includes research, samples, rough and final designs, and a bibliography.
