Stage 18 was used for temporary swing sets in all seven seasons of Star Trek: Deep Space Nine, as well as the motion picture Star Trek: Insurrection. It was used through the four year run of Star Trek: Enterprise and most recently for the 2009 film, Star Trek. According to James Mees, the space underneath Stage 18 was used as a warehouse for Trek props and set pieces following their move from the warehouse in Burbank. The space was 12.000 square feet.
