Range of human action involved at home (8,5)

I believe the answer is:

mountain chain

'range' is the definition.
(synonyms)

'human action involved at home' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'human'+'action'='humanaction'
'humanaction' anagrammed gives 'mountaincha'.
'mountaincha'+'in'='MOUNTAIN CHAIN'

'of' is the link.

I've seen this clue in The Times.
