SIGNET HQ
From Tardis Wiki, the free Doctor Who reference
SIGNET HQ was the headquarters of SIGNET in York. It was a repurporsed hangar, but was equipped with its own car park and a reception desk.
For Halloween, Olivia, with her characteristic enthusiasm, once draped a strip of bunting with "Happy Halloween!" written on it over the hangar doors. (PROSE: Hervoken Halloween [+]Loading...["Hervoken Halloween (short story)"])
