Holy edifice not yet paid for (8)
I believe the answer is:
hallowed
'holy' is the definition.
('hallowed' can be a synonym of 'holy')
'edifice not yet paid for' is the wordplay.
'edifice' becomes 'hall' (hall is a kind of edifice).
'not yet paid for' becomes 'owed'.
'hall'+'owed'='HALLOWED'
(Other definitions for hallowed that I've seen before include "Held holy" , "Reverenced" , "Like saints" , "sacrosanct" , "Consecrated, holy" .)
