Junk TARDIS

The Junk TARDIS was a makeshift TARDIS created by the Eleventh Doctor and Idris (the embodied matrix of his TARDIS) to reach his own TARDIS, which had been hijacked by House.

They built it from bits of TARDISes in the Bubble universe's junkyard, a task which Idris called "impossible". The TARDISes had arrived through the Bubble universe rift and been consumed by House and their Time Lords killed. This TARDIS consisted solely of a console (with time rotor) and three walls. It lacked a proper shell, which the Doctor stated would be very dangerous to travel without.

Unfortunately, the Junk TARDIS could not draw power from the rift energy in the Bubble Universe. It worked only because the Doctor's TARDIS, personified by Idris, powered it and operated the telepathic circuits.

It was highly unstable in flight, but once the Doctor's TARDIS' shields were down, it materialised in an archived control room in the same spot Nephew stood, killing him. The Junk TARDIS was presumably lost when the archived control room was deleted by House. (DW: The Doctor's Wife)
