I try not to pay too much attention to the Sixth Doctor. He makes my head hurt. LOL

I think that the Fourth Doctor did too

He attempted to in Logopolis, even measuring the exterior's "37 dimensions" with Adric, however it failed when The Master began to interfere with the stability of N-space.

You may also be thinking of the secondary console room that shows up in a handful of scenes in seasons 14 and 15, including Sarah Jane's farewell.
