A drawing room (5)
I believe the answer is:
study
I believe this clue is a double definition.
'a drawing' is the first definition.
(study is a kind of drawing)
'room' is the second definition.
(study is a kind of room)
(Other definitions for study that I've seen before include "Analysis" , "Read; examine" , "Something worth observing" , "Work-room" , "Den; a practice drawing" .)
