Final thing fitted into facade at home (5)

I believe the answer is:
death
'final thing' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'fitted into facade at home' is the wordplay.
'fitted into' indicates the answer is hidden within the clue.
'DEATH' is hidden within 'facade at home'.
Can you help me to learn more?
(Other definitions for death that I've seen before include "Extinction" , "Annihilation" , ""The last enemy"" , "The end - after 13 across, the plague" , "Final moments" .)
