The standing sets of Star Trek were located on Stage 9 of Desilu Studios, which would later become Paramount. The permanent rooms were the bridge, the transporter room, engineering, the sickbay complex, Captain Kirk’s quarters and the briefing room. All other sets, like the ship’s chapel, recreation room and gymnasium, were redresses of those existing rooms.
Besides the bridge, the most recurring set was sickbay. The script for the first episode, “Where No Man Has Gone Before,” described sickbay as a “small hospital” with furnishings that are comfortable, “not the usual Spartanish hospital type.”
The Doctor’s office has direct access to a ship’s corridor. There is access from his office to an examination room, also to sickbay proper. Access to sickbay can also be made directly from the corridor. Within the sickbay, there are built-in bed positions with a complete diagnostic panel above each. This medical device scans the patient continually, takes readings, and registers same upon the diagnostic panel instrument face. Thus, blood pressure, pulse rate, heartbeat, respirations, and various other readings are continuously recorded and displayed for each patient without the necessity of physical contact between doctor and patient. Adjoining the Doctor’s office is a medical lab.
Matt Jefferies designed these sets, as he did most of the interiors that appeared on Star Trek.
The captain’s quarters for “The Cage” had been designed by Franz Bachelin. They notably included a television set. When “The Cage” was rejected by the studio but Gene Roddenberry was asked to produce a second pilot, Jefferies came up with a look for Kirk’s quarters that was in keeping with his practical style.
