Ashley House
Ashley House was a building in London. P.R.o.B.e. was based in a single cramped office, which was not what Liz Shaw had been promised.
History
The office had newspaper articles relating to Liz's past career at UNIT, as well as a photograph of Alistair Gordon Lethbridge-Stewart, on the wall. There were facilities in the building for assistant Louise Bayliss to make tea for herself and Liz. (HOMEVID: The Zero Imperative)
In 2000, Louise Bayliss visited Ashley House twice, having previously been transferred to the Home Office by Sir Andrew Williams. One her first visit, Patricia Haggard sent her to ensure the safe containment of the Cyberon being stored at a PKD facility. Louise returned after the job had been completed, although Tom Mordley died after being freed from the Cyberons' control, which was discussed at the house. Patricia told her about Tom's remaining family and Louise asked if there was any chance she could return to P.R.O.B.E., but Patricia politely told her no. (PROSE: The Last Dose)
By 2014, P.R.o.B.e. had expanded and their headquarters were relocated to Parliament Square. (HOMEVID: When to Die)
