Gold leaf walls in Chinese family home (9)
I believe the answer is:
orphanage
'home' is the definition.
(I've seen this before)
'gold leaf walls in chinese family' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'leaf' becomes 'page' (page is a kind of leaf).
'walls in' indicates putting letters inside (inserted letters are walled in).
'chinese family' becomes 'han' (Chinese dynasty).
'page' placed around 'han' is 'phanage'.
'or'+'phanage'='ORPHANAGE'
(Other definitions for orphanage that I've seen before include "building" , "Institution for parentless or abandoned children" , "with deprived children" , "home for kids" , "Parentless children's institution" .)
