TARDIS

"It stands for Time and Relative Dimension in Space" - The Thirteenth Doctor

The TARDIS is the Doctor's most common method of travel through both time and space. Although, quite a few Timelords have been known for using different variants of TARDIS throughout their adventures. TARDISes are common among Timelords for helping take them form A to B along, without time or space being a barrier.

The TARDIS was known to be made up of a control room/flight deck, that contained a functioning control console, equipped with a time rotor and many sections each unique to making the TARDIS fly, and time travel. The flight deck was also known for being a point of entry, as well as, an exit. TARDISes themselves were typically circular, featuring relatively open floor plans, in which the control console is the central feature. Control rooms are usually contained walls, with roundels, scanners for viewing anything within the exterior dimensions of the TARDIS, and fairly sparse furnishings;no known TARDIS control room allowed for the operation of the console itself, from a seated position.

Other than those generalisations, the shape, size and ambience of a control room, even within just the Doctor's TARDIS, was highly variable, as explained below:
