Creator of improved housing for example (8)
I believe the answer is:
begetter
'creator' is the definition.
(thesaurus)
'improved housing for example' is the wordplay.
'improved' becomes 'better' (similar in meaning).
'housing' is an insertion indicator.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'better' going around 'eg' is 'BEGETTER'.
'of' acts as a link.
(Other definitions for begetter that I've seen before include "One producing (child)" , "Parent" , "Father" .)
