Select a location for the theater. Any size location can work; however, the smaller the location, the smaller the stage and audience. The location should also be in an area that is easily accessible for the audience (not out in the middle of nowhere) and have parking nearby.
Draw up plans based on the budget. The budget will determine exactly what can be done with the property and design. Hire an architect or civil engineer to draw up plans for a theater. An architect with experience building theaters is preferred.
Design the stage first; add other elements later. The stage must be large enough to accommodate most performances. Include enough room behind the stage for the crew and also room in the wings for actors and crew. Include space behind the stage for dressing rooms and rehearsal space. The backstage area can be 1/3 the size of the stage.
Design the audience seating. The type of seating will depend on the size and scope of the project. For example, a smaller project would probably not have a balcony. The more seats the theater can accommodate, the higher the potential revenues. Seats should be as small and close together as possible, without compromising patron comfort.
Design the lobby and ticket booth. The lobby is the area where patrons wait before the show and during intermission. It should comfortably accommodate the same number of people as the amount of seats. Having a small area for a refreshment stand is also an option. The lobby should have adjacent bathrooms. Locate the ticket booth at the very front of the theater, so it can be accessed from the street.
Design the decor. The decor for the theater can be anything at all and should match the types of productions that will be performed at the theater. Traditional theaters are usually carpeted, have textured wallpaper and feature lush colors.
