During his travels in the TARDIS, Adric had a bedroom. After his death, (TV: Earthshock) the room was inhabited by the newly arrived Vislor Turlough.
Whilst Adric lived it in he kept a star chart, a tribal mask, shelves of books and a desk with a chair. Turlough described it as looking like a kid's room. (TV: Terminus)
History
On one occasion, the Fifth Doctor entered. Then, he and Adric had an argument in which Adric expressed that he was being teased and that the Doctor never found time for him, only when it was convenient for himself. The Doctor replied that he would try more in the future but Adric gave an example where he had not kept his promise to Tegan. The conversation continued outside his room and ended when Adric told the Doctor of his intentions to return to Alzarius, although this would never happen because of his death soon after. (TV: Earthshock)
The room would be left as Adric left it for a long period of time after his demise. (TV: Earthshock, Terminus)
When Vislor Turlough started travelling in the TARDIS, Adric's room was given to him. His first action of change was to get rid of some items that were messily placed on his bed. (TV: Terminus)
Adric's room was still saved deep within the TARDIS during the time of the Tenth Doctor. (COMIC: Tesseract)
In the Minecraft: Ruinscraft series 'Doctor Who - The Rmijares Adventures' ran by @FunBricks1 and @rmijares, Adric was often in his room, which had a chest filled with berries beside his bed, a mosaic, a teddy bear, and a jukebox. (FANMADE: The Rmijares Adventures)
