I actually liked the sets they made for Logopolis, Castrovalva et.al. Not really detailed and pretty simplistic, but easily re-arranged to convincingly simulate the labyrinth of corridors beyond the console room. They had several different kinds of wall and liberally mixed them around, being pretty effective in the small studio space they had. What we got in "The Doctor's Wife" looked realistic, but IMO they were simplistic compared to the classic series corridors.
Here's hoping that a proper, TARDIS-set episode will spruce up those corridors with more detail (more roundels, dangit!), and add a couple rooms like the drawing room we "saw" in the game, or a better wardrobe. Plus, effective greenscreen to show stuff like the library, boot cupboard, or zeppelin hangar.
