Dorothy's workshop

 was located inside three specially designed shipping containers on Kirkwood Farm.

Appearance
The red and white paintowork on the containers was slightly better than the others lined up. The doors had a digital padlock on them and were made of heavy steel. Unlike other containers on the farm, the walls were capable of swinging up to create a large open space, a prototype from her charity that she had developed to provide tempory buildings in emergency situations as hospitals, barracks, emergency shelters, and what Dorothy like to call her 'Batcave ' .There were motion sensors linked to the lights on the walls, and the walls were lined with cupboards and racks. At the far end of the workspace, behind a plexiglass screen, was a laboratory where she refined the formula for Nitro-9, eventually creating Nitro-90 and making what she called 'anti-plastic'. Around the room were several projects that she had started and then abandoned, including restoring the engine of a Triumph Bonneville T120, which she had hoped to finish in the summer of 2019, but was still in pieces by January 2020. In the middle of a room lay a Rintlekk escape pod that she was still trying to repair.

History
Dorothy was paranoid of Torchwood finding out about her workshop, as it contained all the alien technology that she had salvaged. In January 2020, the Thirteenth Doctor, Yasmin Khan, Graham O'Brien and Ryan Sinclair visited.
