What is a moveable wall with a working door used for in scenery?

A moveable wall with a working door is referred to as a door flat in the context of theatre scenery. This type of set piece is specifically designed with the functionality of a door, allowing actors to enter and exit the stage seamlessly during a performance. Door flats are often created to look like traditional walls but include a door that opens and closes, enhancing the realism of the set while also allowing for dynamic movement within the play.

While other options may involve elements of scenery, they do not possess the unique functionality of a door flat. Scene panels, for example, typically refer to larger sections of scenery that create a backdrop or frame a space but may not include moveable elements. Set pieces can encompass a wide range of objects on stage but do not specifically denote a wall with a working door. A pivot wall is a type of set piece that may rotate or swing to create different perspectives or rooms but does not specifically imply the presence of a door like a door flat does. Thus, the definition and purpose of a door flat make it the most appropriate term for a moveable wall with a working door.
