Room G15
From Tardis Wiki, the free Doctor Who reference
Room G15 of Coal Hill Academy was the Sport Science Office. A small room, it was Coach Dawson's office, where he worked on his laptop. (TV: The Coach with the Dragon Tattoo) The Sport Science Office was in the Barbara Wright Building. (TV: For Tonight We Might Die)
On two boards in that room beside a mirror were the photos of football players for the school's two teams for Years 10 and 11: the 1st Team and the 2nd Team. The room had at least two lockers. Two drawers on the filing cabinet said "football". The office also had a poster on the wall about sports injuries. (TV: The Coach with the Dragon Tattoo)
