Building's inside unfinished if I cease (7)

I believe the answer is:

edifice

'building's' is the definition.
('edifice' can be a synonym of 'building')

'inside unfinished if i cease' is the wordplay.
'inside' indicates a hidden word.
'EDIFICE' is hidden in the letters of 'unfinished if i cease'.

(Other definitions for edifice that I've seen before include "Fine building" , "erection" , "impressive pile!" , "'Large, imposing building (7)'" , "Impressive building" .)

I've seen this clue in The Telegraph.
