To the west, a space in which to create temple (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
'to the west a space in which to create' is the wordplay.
'to the west' is a reversal indicator.
'space' becomes 'gap' (gap is a kind of space**).
'in which' is an insertion indicator.
'to create' becomes 'do' (doing is a kind of creating).
'a'+'gap'='agap'
'agap' going around 'do' is 'adogap'.
'adogap' backwards is 'PAGODA'.
(Other definitions for pagoda that I've seen before include "religious structure" , "A buddhist temple built in tiers" , "Asian temple with up-turned eaves" , "Temple - a GPO ad (anag)" , "Pyramidal temple with an upward curving roof" .)
