4. "Steampunk-Meets-Coral" (2010 - 2012)
With the regeneration of the Tenth Doctor into the Eleventh, the resulting process almost completely destroyed the TARDIS... but as she rebuilt herself, she appeared to have change on her mind! Whilst, at a glance, it looks like a jumbled mess of various household items thrown together in a Swiss Cheese-style room, the multi-levelled Console Room allowed viewers to really feel like this was a home. Staircases and corridors leading to various different rooms (see: "The Doctor's Wife") and even a whole area beneath the console itself. This version of the interior is fantastic for its sheer complexity and for that reason, it comes in at number two in our list.
