Let bowler play in building (4,5)
I believe the answer is:
bell tower
'building' is the definition.
(I know that bell tower is a type of Tower)
'let bowler play' is the wordplay.
'play' is an anagram indicator.
'let'+'bowler'='letbowler'
'letbowler' is an anagram of 'BELL-TOWER'.
'in' is the link.
(Other definitions for bell tower that I've seen before include "building to encourage worshippers to come along?" , "Campanile" .)
