Thatchos's control room

In England by the year 2010, Thatchos, leader of the Cybermen, had a control room.

History
In 2010, when the Doctor and Peri Brown arrived in the TARDIS, they, along with a human they met along the way, travelled to, as identified by the human, Thatchos' control room. While the trio were in the room, Thatchos arrived from around the corner and threatened to privatise them before calling in Denos, who shot a ray gun 2 times over their heads. They then ran back down a series of corridors, back to the TARDIS. (TV: Untitled)

Appearance
Thatchos' control room consisted of at least one room with a corner leading to another section of the room, and an attached series of corridors. The walls were built from dark brown rocks, and the floor was white, and covered in leaves. (TV: Untitled)
