As for other rooms, in various classic series stories we have previously seen: the secondary control room, the cloisters, the sick bay, the swimming pool, a communal living area with a food dispenser and several couches, at least two bedrooms, the power room (which was disguised as an art gallery), a couple of warehouse sized store rooms, a laboratory, a boot cupboard (which was actually a Regency drawing room with a pair of boots in it), several wardrobe rooms, a room containing nothing but a mirror and a hat stand, a 'Zero Room' which was apparently a kind of totally isolated environment, a permanently darkened chamber where the Key to Time was kept, and what appeared to be several miles of corridors, as well as a room full of equipment banks and computers somewhere off the console room. We've also heard mention of kitchens and a library. And in the novels, we saw the library (which seemed to be infinite and to change location at random) and a third control room with a stone control console, as well as a room which appeared to be an open air environment, a grassy hill covered in butterflies. There are probably a few more I've forgotten, too.”
Don't you just love the use of old swimming baths in The Invasion of Time.
