The Doctor's office (The Pilot)
From Tardis Wiki, the free Doctor Who reference
During the 2010s, the Twelfth Doctor had an office on St Luke's University.
He kept many of his belongings on his office, such as many sonic screwdrivers, portraits of River Song and Susan Foreman, and a bust of Ludwig van Beethoven, as well as his TARDIS parked on the corner of the room.
Nardole once took Bill Potts there, and the Doctor asked her why she went to his lectures if she wasn't a studed of the university. (TV: The Pilot)
