Scenery (5)
I believe the answer is:
decor
'scenery' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for decor that I've seen before include "stage background" , "Scheme of interior furnishings" , "Style of furnishing etc used in room" , "furnishings required" , "Colour-scheme etc of a room" .)
