UNIT HQ laboratory

The laboratory of UNIT HQ was used extensively by the Third Doctor during his association with UNIT. During the Doctor's exile on Earth, the Doctor continually worked on trying to fix his TARDIS in the lab.

The Third Doctor had other laboratories away from UNIT HQ; including one in a Welsh barn (COMIC: Gemini Plan) and one in his cottage which was much better equiped than the UNIT lab. (PROSE: Verdigris)

The laboratory had the smell of scorched and burning circuitry. (AUDIO: Find and Replace)

Appearance
Due to either refurbishment (PROSE: Country of the Blind) or the UNIT HQ being relocated to a different building, (PROSE: Where the Heart Is, The Scales of Injustice) the appearance of the UNIT HQ laboratory changed. (TV: The Ambassadors of Death, Terror of the Autons)

The Doctor's TARDIS was kept in the same location in a corner of the room. (TV: Terror of the Autons et al)

The laboratory had green lights which were visible from outside the building where the lab was located. (PROSE: Out of the Green Mist)

(COMIC: The Heralds of Destruction)

The laboratory had a black spiral staircase. (TV: Terror of the Autons, PROSE: Country of the Blind)

During the Third Doctor's exile
When the Third Doctor became UNIT's scientific advisor, he did so on the condition that he would receive a variety of cutting-edge technology with which to repair his TARDIS. (COMIC: The Arkwood Experiment) The Doctor stored some of this technology in the UNIT HQ laboratory. (COMIC: The Metal Eaters, TV: The Ambassadors of Death et al)

During early attempts to fix the TARDIS, the Doctor took the TARDIS control console outside of the ship and into his lab. The Doctor had the television on when he was trying to fix the Time Vector Generator; through this he learned of the loss of contact with the crew of Mars Probe 7. (TV: The Ambassadors of Death)

One account indicates that the Doctor hooked up an interstitial vortex in the lab to prevent a derelict Bathesdan spaceship from crashing into Earth. (PROSE: UNIT Christmas Parties: First Christmas) Another account indicates that the Doctor tried to cook Christmas dinner using the scientific equipment in his lab. While trying to make cranberry sauce, the Doctor accidentally damaged his dimensional stabiliser, creating a hole in reality leading from the Doctor's lab to the sky above a field outside UNIT HQ.

The Master implanted the idea of leaving UNIT in Liz's mind and made her forget he was ever there. (PROSE: Reconnaissance)

Around the time that Liz Shaw left UNIT and Mike Yates joined, the Brigadier had the laboratory redecorated and repainted to improve morale. Liz tried to tell the Doctor that she was going to be leaving UNIT, but he was distracted by the painters and Liz choose to leave the room rather than continue to try to get the Doctor's attention. (PROSE: Country of the Blind)

Jo Grant met the Doctor while he was working in his laboratory. During Jo's first adventure with the Doctor, the Master hypnotised her into bringing a bomb into the laboratory. The Doctor disposed of the bomb by throwing it outside, into the river. Later, the Master came into the lab disguised as a telephone engineer and replaced the Doctor's telephone cord with a plastic one which could be controlled by the Nestene Consciousness. The Master tried to have the cord strangle the Doctor when he used the phone, but the Doctor was saved from the cord by the Brigadier. (TV: Terror of the Autons)

Dr Tyler visited the Doctor's laboratory for consultation after he picked up some strange cosmic rays, accidentally bringing an anti-matter organism to the lab. The Doctor, Jo, and John Benton hid in the TARDIS after seeing the organism and were unable to stop it sending almost the entire contents of the lab to the anti-matter universe, with the TARDIS being protected by its force field. After the organism began sending parts of the laboratories' walls to the anti-matter universe, the Third Doctor and Jo left the TARDIS and got sent to the anti-matter universe. The Second Doctor and Benton safely exited the TARDIS and met up with the Brigadier. The organism later sent the rest of the laboratory to the anti-matter universe along with the rest of UNIT HQ.

Shortly after the incident involving the three Doctors, Ramón Salamander came to the UNIT HQ laboratory disguised as the Second Doctor and scanned the interior of the Doctor's newly-working TARDIS. When the Doctor and Jo came to the lab, Salamander distracted them by infecting Jo with his micro machines. With the Doctor going into a trance state to repel the micro machines from Jo's mind, Salamander was able to record enough data from the TARDIS to recreate Time Lord technology at Electronicon Ltd. While the Doctor and Jo were still mentally fighting the micro machines, the Master entered the laboratory disguised as the Brigadier and hid the real Brigadier in a cupboard. The Doctor was able to instantly see through the Master's disguise when he woke up from his trance. The Doctor and the Master then united to stop Salamander from messing with history.

At this time there were plans to empty the lab and convert it into a computer room. (PROSE: An Overture Too Early)

When Katharine Delbane broke into UNIT HQ, the laboratory was covered in a film of dust. It reminded Katharine of the "untouched, shrine-like way in which some of the people in Belfast kept the rooms of loved ones who had been roughly deleted from their lives". (PROSE: Heart of TARDIS)

Other realities
When the Cybermen allied with Rassilon to rewrite all of history, (COMIC: Supremacy of the Cybermen) the laboratory was hit by a time distortion during a conflict between the Third Doctor and the Master and a cyber-conversion unit was added to the room. (COMIC: Prologue: The Third Doctor)
