Many of the Year 1 set elements are reused, including the Big Screen and the arches. The computer panels are new, and more colourful (they were created for Into Infinity).
Unlike Year 1, the principal characters rarely interact directly with the computer walls (Maya performs some operations in Journey to Where and The Immunity Syndrome). Tasks such as retrieving information from the main computer memory banks are instead carried out using the computer desk terminals. The supporting cast is however frequently seen checking the positions of the Main Computer switches using checklists.
The four principal desks have Domani swivel chairs, like Koenig's but without a headrest. The side desks have Gaudi chairs (as in Year 1).
The left side wall of Command Centre is rarely seen, as the camera was almost invariably on that side. Unlike Main Mission, the set was designed and built without the left side. Only in a few specific scenes was the wall required - usually for a reverse shot between two characters looking at each other. In these cases, they simply filmed against the right wall, covered in computers, turning a desk around if required. The overall plan of the room must be a zig-zag. Shots are seen in The Metamorph (shots of Tony during a conversation with Sandra), Brian the Brain (reverse shots of Tony at his desk), and The AB Chrysalis (Koenig crouches by his desk, waiting for the shockwave)
Command Centre measured 32.5 ft (9.91 m) in length and 32 ft (9.75 m) in width. Overall height was 12 ft (3.66 m), with a ceiling height of 8 ft (2.44 m), apart from a high bay, set at 10 ft (3.05 m). Standard bulkhead thickness was 4 ft (1.22 m).
