House viewers? (8)
I believe the answer is:
audience
I believe this is a double definition.
'house' is the first definition.
(I've seen this before)
'viewers?' is the second definition.
(viewers is a kind of audience)
(Other definitions for audience that I've seen before include "Formal interview; those at e.g. play" , "Auntie doesn't like seeing one shrink?" , "Formal or ceremonial interview" , "Formal interview with ruler or VIP" , "A gathering to watch and hear" .)
